1/39 “METHOD FOR PROVIDING AN AIRCRAFT ALERT FOR A SEARCH AND RESCUE SYSTEM, APPLIANCE, AND, SYSTEM”
FUNDAMENTALS [001] The present invention generally concerns the identification, location, and response to an aircraft in distress. More particularly, the present invention relates to a method and apparatus for providing an aircraft alert to a search and rescue system to respond to the aircraft in distress.
[002] Many aircraft carry radio beacons of danger. Hazard radio beacons may be known as emergency beacons or by other names. For example, without limitation, many commercial passenger aircraft and other aircraft can carry a radio hazard beacon, known as an emergency locator transmitter, ELT.
[003] An emergency locator transmitter on an aircraft is intended to assist in locating the aircraft after an impact. An emergency locator transmitter on an aircraft can be activated manually or automatically to send a danger signal when the aircraft is in danger. For example, without limitation, an emergency locator transmitter can be activated to transmit a danger signal automatically when immersed in water or when another condition indicating that the aircraft is in danger is detected.
[004] A search and rescue system can detect a hazard signal generated by an emergency locator transmitter or other hazard radio beacon on an aircraft and respond in an appropriate manner. For example, COSPAS-SARSAT is an international humanitarian search and rescue system to locate and respond to aircraft, ships, or individuals in distress. The COSPAS-SARSAT system includes a network of satellites, ground stations, mission control centers, and
2/39 rescue coordination.
[005] COSPAS-SARSAT uses satellites to detect transmissions of danger signals from emergency locator transmitters on the aircraft. A signal from an emergency locator transmitter on an aircraft is received by a satellite in the COSPAS-SARSAT system and relayed to the nearest available ground station. The ground station, called a Local User Terminal, processes a signal and determines the position from which it originated. The primary means of determining the transmission position of the emergency locator transmitter is the use of satellite orbit information and signal Doppler measurements. In some cases, an emergency locator transmitter can be configured to determine its location using a satellite navigation system receiver that is either integrated into the emergency locator transmitter or powered by a satellite navigation system receiver that is not part of the emergency locator transmitter.
[006] The information identifying the position of the emergency locator transmitter is transmitted from the ground station to a mission control center where it is gathered with identification data and other information associated with the emergency locator transmitter. The mission control center then transmits an alert message to an appropriate rescue coordination center based on the determined geographic location of the detected transmission from the emergency locator transmitter and other available information.
[007] Current emergency locator transmitters may have several limitations. For example, the position information provided by current emergency locator transmitters cannot be sufficiently accurate or provided in a manner sufficiently reliable to efficiently locate an aircraft in distress. Most emergency locator transmitters currently in the field do not provide
3/39 position information directly. The location of the emergency locator transmitter is determined by looking for direction by radio frequency or multilateration through satellite connections. This process can take an undesirably long time and may not be reliable enough. [008] The weight of current emergency locator transmitters can be relatively high. Maintenance requirements for current emergency locator transmitters can also be relatively high. For example, most emergency locator transmitters equipped on aircraft today are powered by a non-rechargeable battery that is relatively heavy and must be properly maintained to ensure reliable operation and to prevent any unwanted conditions from occurring. Also, it can be relatively difficult to reduce or eliminate unwanted unauthorized manipulation from current emergency locator transmitters.
[009] Consequently, it would be beneficial to have a method and apparatus that takes into account one or more of the issues discussed above, as well as other possible issues.
SUMMARY [0010] The illustrative modalities of the present invention provide a method for providing an aircraft alert for a search and rescue system. An aircraft alert is received via a communications satellite. The alert comprises identification information identifying the aircraft and position information identifying the aircraft's position. In response to receiving the alert, an emulated danger radio beacon signal is generated. The emulated hazard radio beacon signal includes identification information and position information in a standard format of a signal generated by a hazard radio beacon. The emulated hazard radio beacon signal is broadcast from a different location on the aircraft as an emulated hazard radio beacon transmission that is
4/39 configured to be received and processed by the search and rescue system.
[0011] The illustrative embodiments of the present invention also provide an apparatus comprising a receiver, a formatter, and a transmitter. The receiver is configured to receive an aircraft alert via a communications satellite. The alert comprises identification information identifying the aircraft and position information identifying the aircraft's position. The formatter is configured to generate an emulated danger radio beacon signal comprising identification information and position information in a standard format from a signal generated by a radio hazard beacon. The transmitter is configured to broadcast the emulated hazard radio beacon signal from a location other than the aircraft as an emulated hazard radio beacon transmission that is configured to be received and processed by a search and rescue system.
[0012] The illustrative modalities also provide a system comprising an aircraft tracking device, an aircraft tracking system, and a search and rescue system. The tracking device is configured to send an aircraft alert via a communications satellite, where the alert comprises identification information identifying the aircraft and position information identifying the aircraft's position. An aircraft tracking system is configured to receive the aircraft's alert, generate an emulated radio hazard signal beacon comprising identification information and position information in a standard format of a signal generated by a radio hazard signal. , and broadcast the emulated danger radio beacon signal from a location other than the aircraft as an emulated danger radio beacon transmission. The search and rescue system is configured to receive the emulated danger radio beacon transmission as an
5/39 transmission of standard danger radio beacons via a search and rescue satellite and using identification information and position information to conduct the search and rescue operation.
[0013] The illustrative modalities of the present invention also provide a method for using an aircraft alert to perform the search and rescue operation. An apparent hazard radio beacon transmission comprising identification information identifying the aircraft and position information identifying the aircraft's position is received. The identifying information is used to identify registration information for the aircraft indicating whether the apparent hazard radio beacon transmission is an emulated hazard radio beacon transmission, transmitted from a transmitter that is not a positioned hazard radio beacon on the aircraft. Identification information and position information are used to perform the search and rescue operation in response to a determination that the apparent danger radio beacon transmission is an emulated danger radio beacon transmission transmitted from a non-transmitter. it is a radio beacon of danger positioned on the aircraft.
[0014] Various characteristics, functions, and benefits can be obtained independently in the various modalities of the present invention or can be combined in still other modalities in which other details can be seen with reference to the following description and drawings.

DETAILED DESCRIPTION [0016] Different illustrative modalities recognize and take into account a number of different considerations. “A number”, when used here with reference to items, means one or more items. For example, “a number of different considerations are one or more different
7/39 considerations.
[0017] The different illustrative modalities recognize and take into account that many of the limitations of an emergency locator transmitter can be overcome by replacing the emergency locator transmitter on an aircraft with an Iridium-based tracking system. The different illustrative modalities also recognize, however, that the current search and rescue system COSPAS-SARSAT is not configured to receive alerts from such a tracking system.
[0018] Illustrative modalities provide a system and method for receiving alerts and position information from an aircraft tracking device and relaying alerts in a format appropriate for the current COSPAS-SARSAT system. According to an illustrative embodiment, an alert received from the tracking device on an aircraft can be converted into an emulated emergency locator transmitter signal that can be broadcast using a transmitter that emulates a transmission from an emergency locator transmitter.
[0019] Returning to figure 1, an illustration of an aircraft operating environment is represented according to an illustrative modality. The operating environment of aircraft 100 can include any appropriate environment in which aircraft 102 can be operated in any appropriate manner.
[0020] Aircraft 102 can be any appropriate type of aircraft that can be configured to perform any appropriate operation or mission in the operating environment of aircraft 100. For example, without limitation, aircraft 102 can be a commercial passenger aircraft or any other appropriate type of aircraft.
[0021] The operating environment of aircraft 100 may include search and rescue system 104. Search and rescue system 104 may comprise various systems and personnel to respond to an alert
8/39 that aircraft 102 is in danger. For example, without limitation, the search and rescue system 104 may comprise the COSPAS-SARSAT search and rescue system.
[0022] The search and rescue system 104 may comprise satellites 106 of the search and rescue system and ground facilities 108. The satellites 106 of the search and rescue system may comprise satellites in low-altitude earth orbit, satellites in geostationary orbits, or both. The search and rescue system satellites are configured to detect radio beacon transmissions of danger, such as emergency locator transmitters, and to relay such transmissions to ground facilities 108.
[0023] Ground installations 108 are configured to receive danger radio beacon transmissions relayed from search and rescue system satellites 106, process danger radio beacon transmissions, and conduct appropriate search and rescue operations , in response. For example, without limitation, ground facilities 108 may include multiple response centers having multiple resources to respond to various hazardous situations. Ground facilities 108 can be configured to process incoming radio hazard beacon transmissions to identify and notify the appropriate response center or centers to respond to the particular hazard situation.
[0024] According to an illustrative embodiment, aircraft 102 may include tracking device 112. For example, without limitation, tracking device 112 may be affixed to aircraft liner 102 on the outside of aircraft 102. According to an illustrative embodiment, tracking device 112 can be configured to automatically determine aircraft position 102, to determine when aircraft 102 is in danger, and to send an alert including position information identifying aircraft position 102 when
9/39 aircraft 102 is determined to be in danger, [0025] Tracking device 112 can be configured to identify aircraft position 102 using navigation signals 114 received from a number of satellites 116 of the navigation system, in a manner known. Tracking device 112 may use navigation signals 114 received from more than three satellites 116 of the navigation system to determine aircraft position 102. For example, without limitation, satellites 116 of the navigation system may include satellites in the navigation system 117 satellite systems, such as the Global Positioning System, GPS, the Global Navigation Satellite System, GLONASS, other appropriate satellite navigation systems, or various combinations of satellite navigation systems that can be used by the 112 tracking device to determine aircraft position 102.
[0026] According to an illustrative modality, the tracking device 112 on the aircraft is not a conventional emergency locator transmitter or other conventional danger radio beacon. According to an illustrative embodiment, tracking device 112 is configured to send an alert including position information to aircraft tracking system 118 via communications satellite 120.
[0027] For example, without limitation, the aircraft tracking system 118 may be a global aircraft tracking system. The aircraft tracking system 118 can be operated by any appropriate organization. For example, without limitation, when aircraft 102 is a commercial passenger aircraft, aircraft tracking system 118 may be operated by an airline. Alternatively, the aircraft tracking system 118 can be operated by a third party for a number of air transport companies or other aircraft operators 102.
10/39 [0028] Communications satellite 120 may comprise any appropriate communications satellite or a plurality of appropriate satellites to establish a communications link between tracking device 112 on aircraft 102 and aircraft tracking system 118. The device Tracking 112 can be configured to send alerts, including position information identifying aircraft position 102, from tracking device 112 to aircraft tracking system 118 via the communications link established using communications satellite 120. For example , without limitation, communications satellite 120 may be a communications satellite in low-altitude earth orbit. A low-altitude orbiting satellite is in orbit around the Earth with an altitude between approximately 160 kilometers and 2000 kilometers. For example, without limitation, communications satellite 120 may be an Iridium communications satellite in the Iridium satellite constellation, operated by Iridium Communications.
[0029] The search and rescue system 104 cannot be configured to receive an alert transmitted from tracking device 112 on aircraft 102. According to an illustrative embodiment, however, aircraft tracking system 118 may include appropriate facilities for receiving an alert transmission from tracking device 112 on aircraft 102, evaluating the alert, and transmitting the alert in an appropriate format to be received and processed by search and rescue system 104. For example, without limitation, the aircraft tracking system 118 can be configured to evaluate an alert received from tracking device 112 on aircraft 102 to determine whether the alert indicates that aircraft 102 is in danger.
[0030] The appropriate action by search and rescue system 104 may be desired or required when aircraft 102 is in danger. If action by the search and rescue system 104 is desired or required, the search
11/39 aircraft tracking 118 can generate the emulated danger radio beacon signal 122. The emulated danger radio beacon signal 122 may include identification information identifying aircraft 102 and position information identifying aircraft position 102, when alert received from tracking device 112 on aircraft 102. The emulated danger radio beacon signal 122 may be in a standard format of a signal generated by a radio hazard beacon. For example, without limitation, the emulated danger radio beacon signal 122 may be in the standard format of an emergency locator transmitter transmission on an aircraft. The aircraft tracking system 118 can broadcast the emulated danger radio beacon signal 122 as an emulated danger radio beacon transmission that is configured to be received and processed by the search and rescue system 104. The search beacon signal emulated hazard radio 122 can be broadcast from a location other than on aircraft 102 using any appropriate transmitter 124 that is configured to emulate a transmission from a hazard radio beacon on an aircraft. For example, without limitation, transmitter 124 may be located on the ground. [0031] The emulated danger radio beacon signal 122 can be received by satellites 106 from the search and rescue system and retransmitted to ground installations 108 to the search and rescue system 104 in a normal manner. Search and rescue system 104 can thus be notified of, and respond to, an alert generated by tracking device 112 on aircraft 102 without significant changes to search and rescue system 104.
[0032] Returning to figure 2, an illustration of a block diagram of an aircraft operating environment is represented according to an illustrative modality. The aircraft operating environment 200 can be an example of an implementation of aircraft operating environment 100 in figure 1. The aircraft operating environment 200 can
12/39 comprise aircraft 202, aircraft tracking system 204, and search and rescue system 206.
[0033] Aircraft 202 can be any appropriate type of aircraft that can be configured to perform any appropriate operation or mission in the operating environment of aircraft 200. For example, without limitation, aircraft 202 may be a commercial passenger aircraft, a cargo aircraft, military aircraft, or any other appropriate type of aircraft. Aircraft 202 may be a fixed-wing aircraft, a rotary-wing aircraft, or an aircraft lighter than air. Aircraft 202 may be a manned aircraft or an unmanned aircraft.
[0034] Prior to the operation of aircraft 202 in the operating environment of aircraft 200, registration information 207 for aircraft 200 may be provided to the search and rescue system. Log information 207 can comprise the same type of information that would be required by search and rescue system 206 to respond to a transmission from a current emergency locator transmitter on an aircraft. For example, without limitation, log information 207 may include information connecting aircraft identification information to a hazard radio beacon signal received from the aircraft operator, appropriate contact information, an appropriate regulatory authority that should be contacted at a emergency situation, or other appropriate information. The aircraft's position at the time of receiving the hazard signal may determine that the Air Navigation Service Unit should also be contacted.
[0035] For example, without limitation, log information 207 may notify search and rescue system 206 that an apparent danger radio beacon transmission from aircraft 202 is not from a radio hazard beacon on aircraft 202, but is from aircraft tracking system 204. Registration information is provided to the search and retrieval system
13/39 rescue 206 so that the search and rescue system 206 can respond appropriately when an apparent danger radio beacon transmission from aircraft 202 is received by the search and rescue system 206.
[0036] Aircraft 202 includes tracking device 208. Tracking device 208 can be configured to send alert 210 to aircraft tracking system 204 via communications satellite 212. Communications satellite 212 can be a satellite communications in low-altitude terrestrial orbit 214. For example, without limitation, communications satellite 212 may be the communications satellite Iridium 216.
[0037] Alert 210 may indicate that aircraft 202 is in danger and may include position information identifying aircraft position 202. Aircraft tracking system 204 may assess alert 210 and broadcast the radio beacon transmission. emulated 218. The emulated danger radio beacon transmission 218 may include information identifying aircraft 202 and position information identifying aircraft position 202 and may be in the form of a transmission of a radio hazard signal that can be received and processed search and rescue system 206.
[0038] For example, without limitation, the search and rescue system
206 may comprise the COSPAS-SARSAT 219 search and rescue system or other appropriate search and rescue system that may be configured to receive and process the transmission of standard danger radio beacon 220 from danger radio beacon 222 on an aircraft to perform the search and rescue operation. The signals in the standard danger radio beacon transmission 220 of the danger radio beacon 222 may be in the standard format 224 of signals generated by the danger radio beacon 222.
[0039] The search and rescue system 206 can receive transmission
14/39 of emulated danger radio beacon 218 and use the information provided in the transmission of emulated danger radio beacon 218 together with registration information 207 to aircraft 202 to conduct an appropriate search and rescue operation. According to an illustrative embodiment, the emulated danger radio beacon transmission 218 may be in the standard format 224 of the standard danger radio beacon transmission 220 of the danger radio beacon 222 on an aircraft. Accordingly, the search and rescue system 206 can receive and process the emulated danger radio beacon transmission 218 to conduct an appropriate search and rescue operation in the same or similar manner as in which the radio beacon transmission standard danger signal 220 of the radio hazard signal 222 on an aircraft is received and processed by the search and rescue system 206.
[0040] Returning to figure 3, an illustration of a block diagram of an aircraft tracking system is represented according to an illustrative modality. The aircraft tracking system 300 can be an example of an implementation of the aircraft tracking system 118 in figure 1 and the aircraft tracking system 204 in figure 2.
[0041] The aircraft tracking system 300 may include the receiver 302, the evaluator 304, and the danger radio beacon emulator 306. [0042] The receiver 302 may include any appropriate communications system including a communications receiver. satellite to receive alert 308 from an aircraft via a communications satellite. Alert 308 may include identification information 310, position information 312, hazard information 314, and other information 318. Hazard information 314 may indicate that alert 308 is hazard alert 316. Alternatively, other information 318 may indicate that alert 308 is another alert 320 other than danger alert 316.
15/39 [0043] Evaluator 304 can be configured to assess whether the alert
308 is a danger alert 316 or another alert 320. The evaluation performed by the evaluator 304 can be performed automatically by a computer system or by a computer system in combination with a human operator.
[0044] For example, without limitation, the danger radio beacon emulator 306 can be the emergency locator transmitter emulator 322. The danger beacon emulator 306 can comprise formatter 324 and transmitter 326. In response to alert 308 being determined to be danger alert 316 by evaluator 304, formatter 324 can generate emulated danger radio beacon signal 328. Formatter 324 can be configured to generate emulated danger radio beacon signal 328 in a standard format of a signal generated by a danger radio beacon. For example, without limitation, the emulated hazard radio beacon signal 328 may be an emulated emergency locator transmitter signal 330 in a standard format of a signal generated by an emergency locator transmitter. The emulated hazard radio beacon signal 328 may include identification information 332 identifying the aircraft from which alert 308 was received, position information 334 identifying the aircraft's position as identified in alert 308, and other information 336.
[0045] Transmitter 326 can be configured to broadcast the emulated hazard radio beacon signal 328 as emulated hazard radio beacon transmission 338. For example, without limitation, transmitter 326 can be configured to broadcast the transmitter signal emulated emergency locator 330 as transmitter transmission emulated emergency locator 340. For example, without limitation, the emulated emergency locator transmitter transmission 340 can be encoded by formatter 324 and broadcast by transmitter 326 according to the standards of
16/39 emergency locator transmitter for signal modulation, message format, repetition rate, energy, other characteristics, or various combinations of characteristics of a standard emergency locator transmitter transmission. For example, without limitation, transmitter 326 can broadcast emulated emergency locator transmitter transmission 340 at approximately 406 MHz or any other appropriate frequency to emulate a transmission from a standard emergency locator transmitter.
[0046] Returning to figure 4, an illustration of a block diagram of a search and rescue system is represented according to an illustrative modality. Search and rescue system 400 can be an example of an implementation of search and rescue system 104 in figure 1 and search and rescue system 206 in figure 2. For example, without limitation, search and rescue system 400 can understand search and rescue satellites 402, ground stations 404, mission control center 406, and response center 408.
[0047] Search and rescue system satellites 402 are configured to detect radio beacon transmission of apparent danger 410 and retransmit radio beacon transmission of apparent danger 410 to ground stations 404. Ground stations 404 are configured to receive and process the apparent danger radio beacon transmission 410 from search and rescue system satellites 402. Ground stations 404 can extract identification information 412, position information 414, and other information 416 transmission received from apparent danger radio beacon 410 and transmit that information to mission control center 406. Ground stations 404 may also include position calculator 418 to determine the calculated position 420 of the beacon transmission transmission. apparent hazard radio 410 using satellite orbit information and signal Doppler measurements from a
17/39 known manner. Calculated position 420 can also be provided for mission control center 406.
[0048] Mission control center 406 can receive information from ground stations 404 and exchange information with other mission control centers 422. Mission control center 406 can use registration information 424 in the registration database 426 to determine whether the apparent hazard radio beacon transmission 410 is an emulated hazard radio beacon and to determine the appropriate response center 408 to be notified. Registration information 424 may include, for example, without limitation, identification information 428, transmitter information 430, and other information 432.
[0049] The transmitter information 430 in the registration information
424 may indicate that an aircraft's apparent hazard radio beacon transmission 410, identified by identification information 428, is an emulated hazard radio beacon transmission. Transmitter information 430 can also identify transmitter position 434 of the source of the emulated hazard radio beacon transmission. The mission control center 406 may comprise the validator 436 to validate a transmission received from an emulated danger radio beacon by comparing the calculated position 420 for the transmission with the transmitter position 434, as identified in the registration information 424.
[0050] Response center 408 may include resources 438 to perform search and rescue operations. Response center 408 may use the information provided by mission control center 406 to use resources 438 in an appropriate manner to perform the search and rescue operation in response to the transmission received from the emulated danger radio beacon.
[0051] The illustrations in figures 2 to 4 are not intended to imply physical or architectural limitations to the way in which different
18/39 illustrative modalities can be implemented. Other components in addition to, instead of, or in addition to, and instead of those illustrated, may be used. Some components may be unnecessary in some illustrative modalities. Also, the blocks are presented to illustrate some functional components. One or more of these blocks can be combined, divided, or combined and divided into different blocks, when implemented in different illustrative modalities.
[0052] Returning to figure 5, an illustration of a block diagram of a tracking device is represented according to an illustrative modality. Tracking device 500 can be an example of an implementation of tracking device 112 on aircraft 102 in figure 1 or tracking device 208 on aircraft 202 in figure 2. For example, without limitation, tracking device 500 can be affixed to aircraft 501 on the outer side 502 of aircraft 501. [0053] The tracking device 500 comprises several electronic components contained in housing 504. Housing 504 can be made in any appropriate manner from any suitable material so that the electronic components contained in housing 504 are protected to maintain proper operation of tracking device 500 when tracking device 500 is attached to aircraft 501, on the outside of aircraft 502 501. For example, without limitation, electronic components can be hermetically sealed 506 inside 508 of housing 504. The electronic components can be hermetically sealed 506 inside 508 of the housing 504 using any appropriate materials and structures to provide an air-tight seal between the interior 508 of the housing 504 and the outer side 502 of aircraft 501 when the tracking device 500 is attached to aircraft 501, on the outer side 502 of the aircraft 501. The electronic components for the tracking device 500 may include the receiver
19/39 of satellite navigation system 510, number of antennas 512, satellite communications transceiver 514, hazard identifier 516, and processor 518.
[0054] The satellite navigation system receiver 510 can be configured to receive satellite navigation signals in a satellite navigation system via numerous antennas 512. For example, without limitation, the satellite navigation system receiver 510 can be configured to use the satellite navigation system receiver antenna 519 on a number of antennas 512 to receive the navigation signals. For example, without limitation, the satellite navigation system receiver 510 can be configured to receive satellite navigation signals in a global navigation satellite system, such as the Global Positioning System (GPS), the Satellite Navigation System Global Navigation (GLONASS), another appropriate satellite navigation system, or various combinations of satellite navigation systems. According to an illustrative embodiment, the navigation signals received by the satellite navigation system receiver 510 can be used to determine the position of the aircraft 501.
[0055] The satellite communications transceiver 514 can be configured to send and receive information through a satellite communications system. For example, without limitation, the satellite communications transceiver 514 can be configured to send and receive information via appropriate satellites in low-earth orbit, such as satellites on the Iridium network, other suitable satellites, or several appropriate satellites of various combinations of satellite communications systems.
[0056] According to an illustrative embodiment, the satellite communications transceiver 514 can be used to send the position information 520 to a receiving station via a satellite. THE
20/39 position information 520 may include information identifying the position determined using the navigation signals received by the satellite navigation system receiver 510. In different ways, the position information 520 can be augmented by additional information, such as time marks , and other aircraft navigation data or aircraft status data.
[0057] Satellite communications transceiver 514 can also be used to send identification information 522, alert 524, other information 525, or various combinations of information appropriate to a receiving station via a satellite. The identifying information 522 may include information identifying aircraft 501. Alert 524 may include information indicating that aircraft 501 is in danger.
[0058] The satellite communications transceiver 514 can also be configured to receive instructions 526 through a satellite. For example, without limitation, instructions 526 may include instructions for controlling the operation of the electronic components for the tracking device 500.
[0059] Satellite communications transceiver 514 can use satellite communications antenna 530 on a number of antennas 512 to send and receive communications from a communications satellite. Alternatively, the satellite communications transceiver 514 and satellite navigation system receiver 510 can share the use of shared antenna 532 over a number of antennas 512. In this case, the duplexer 534 or other appropriate device can be used to separate and directing the appropriate signals from the shared antenna 532 to the satellite navigation system receiver 510 and the satellite communications transceiver 514 and to direct any signals from the satellite communications transceiver 514 to the shared antenna 532.
21/39 [0060] Hazard identifier 516 can be configured to identify when aircraft 501 is in danger. The functions performed by hazard identifier 516 can be implemented in hardware or in software running on hardware. For example, without limitation, the functions performed by hazard identifier 516 can be implemented, in whole or in part, in software running on processor 518. Alternatively, the functions performed by hazard identifier 516 can be implemented entirely separately from processor 518.
[0061] Hazard can include any unwanted condition of aircraft 501. Hazard identifier 516 can be configured to identify when aircraft 501 is in danger, automatically, in any appropriate manner. For example, without limitation, hazard identifier 516 may determine that aircraft 501 is in danger when power for operating electronic components to tracking device 500 that is provided on power line 536 from power source 538 inside 540 of aircraft 501 is interrupted.
[0062] In some distinct modalities, a list or matrix of indicators that aircraft 501 is in danger, or factors associated with aircraft 501 in danger, can be stored in storage 541 and used by hazard identifier 516 to automatically determine that the 501 aircraft is in danger. Examples of indicators that the 501 aircraft is in danger may include abnormal changes in position, abnormal deviations from flight plans, and commanded abnormal changes to the 501 aircraft configuration, which could put the aircraft at risk.
[0063] Alternatively, or in addition, hazard identifier 516 can be configured to identify when aircraft 501 is in danger in response to operation of manual actuator 542 by a human operator. Manual actuator 542 can comprise any appropriate actuation or signaling device that can be operated manually by an operator
22/39 human inside aircraft 540 501. For example, without limitation, hazard identifier 516 may determine that aircraft 501 is in danger in response to manual activation of a switch or other appropriate manual actuator 542 by a human operator in the interior 540 of aircraft 501. In this case, the switch or other appropriate actuator of the manual actuator 542 can be connected to provide an appropriate signal to indicate the danger to hazard identifier 516 either by a wire or wirelessly, in any way. appropriate way.
[0064] Preferably, no interface or other capability is provided for a human operator within 540 of aircraft 501 to inhibit or cancel any such hazard indication that is provided for, or determined by, hazard identifier 516. Limiting interfaces for Controlling the operation of the tracking device 500 from the interior 540 of the aircraft 501, in this way, can reduce or eliminate accidental or intentional tampering with the desirable operation of the tracking device 500.
[0065] Hazard identifier 516 may provide an appropriate indication for processor 518 in response to automatic or manual hazard identification by hazard identifier 516. An indication that aircraft 501 is in danger may be provided with hazard identifier 516 for the 518 processor, in any appropriate manner and form.
[0066] Processor 518 can be configured to control the operation of tracking device 500 including satellite navigation system receiver 510 and satellite communications transceiver 514. For example, processor 518 can be configured to use the receiver satellite navigation system 510 to determine the position of aircraft 501 and to generate position information 520 identifying the position of aircraft 501 when identified using the satellite navigation system receiver 510. Processor 518 can be configured to use
23/39 the satellite communications transceiver 514 for sending position information 520 to a receiving station via a satellite. Processor 518 can be configured to automatically generate and send position information 520 at rate 544 while aircraft 501 is in flight.
[0067] Rate 544 can be defined at fixed intervals.
Alternatively, processor 518 can be configured to change rate 544 to generate and send position information 520 based on various conditions. For example, processor 518 can be configured to change rate 544 to generate and send position information 520 based on the geographic location of aircraft 501. For example, without limitation, processor 518 can be configured to send updates to information of position 520 most often when aircraft 501 is flying over the ocean or at another remote location. Processor 518 can be configured to send position information updates less frequently when aircraft 501 is in flight at a location where aircraft 501 may be in view of an air traffic control radar system or at another location less remote. Processor 518 can also be configured to generate and send position information 520 more frequently when it is determined that aircraft 501 is in danger.
[0068] Processor 518 can also be configured to generate and send alert 524 when it is determined that aircraft 501 is in danger. For example, alert 524 can be generated and sent by processor 518 to a receiving station via a satellite together with, or in addition to, position information 520 transmitted using satellite communications transceiver 514. For example, without limitation, alert 524 may include, or be associated with position information 520 identifying the position of aircraft 501 when the hazard begins. For example, without limitation, alert 524 may include information identifying
24/39 various characteristics of the hazard, such as the condition or event that triggered the hazard indication or any other appropriate information or various combinations of information about the hazard.
[0069] Processor 518 can also be configured to take appropriate action in response to instructions 526 received via a satellite and satellite communications transceiver 514. For example, without limitation, processor 518 can be configured to generate and send position information 520, change rate 544 to generate and send position information 520, or take other appropriate actions or various combinations of actions in response to instructions 526 received via the satellite communications transceiver 514.
[0070] Electronic components for the tracking device
500 may include the 546 power supply. The 546 power supply may be implemented in any appropriate manner to provide the appropriate electrical power for the operation of the various electronic components in the tracking device 500 of the electrical power provided for the 546 power supply in the power line 536. For example, without limitation, in the case where tracking device 500 is attached to aircraft 501 on the outside of aircraft 502 502, power line 536 can be connected to provide electrical power for the power supply 546 of the power source 538 inside 540 of the aircraft 501. The power source 538 can comprise any source of electrical power suitable for the operation of the tracking device 500.
[0071] Power line 536 can be implemented in any appropriate manner to provide electrical power from an appropriate power source 538 for power supply 546 on tracking device 500. Various undesirable conditions on power line 536 can cause inconsistencies in the 546 power supply or other electronic components in the tracking device 500. For example,
25/39 without limitation, power line 536 can include circuit breaker 548. Circuit breaker 548 can be implemented in any known and appropriate manner to prevent undesirable conditions on power line 536 from reaching power supply 546 or other electronic components in the tracking device 500. For example, without limitation, circuit breaker 548 can be implemented in a known and appropriate manner to prevent excessive current, excessive voltage, excessive energy, or any other undesirable condition or combination of undesirable conditions on the 536 power line reach the 546 power supply and other electronic components for the tracking device 500.
[0072] The electrical power for the operation of the tracking device 500 can include battery 549. Battery 549 can be contained in housing 504 together with the other electronic components of tracking device 500. Battery 549 can include any type and number batteries to provide the appropriate electrical power for the operation of the various electronic components in the tracking device 500. The power for the operation of the tracking device 500 can be provided by battery 549 as an alternative or in addition to the power supply for the operation of the tracking device 500 of the power source 538 through the power line 536. For example, without limitation, when power for the operation of the tracking device 500 is available from both battery 549 and power source 538 per Through power line 536, battery 549 can be used to provide backup power for device operation. tracking 500 when power on power line 536 is interrupted. For example, without limitation, when the tracking device 500 is attached to the aircraft 501, on the outer side 502 of aircraft 501, the provision of battery 549 to power the tracking device 500 may prevent accidental disabling or
26/39 intentionally the operation of the tracking device 500 from the interior 540 of the aircraft 501 by interrupting power to the tracking device 500 which is provided in the power line 536 of the power source 538 positioned inside the 540 of the aircraft 501.
[0073] The different components illustrated for the tracking device 500 are not intended to provide architectural limitations to the way in which the different modalities can be implemented. The different illustrative modalities can be implemented in a system including components in addition to, or in place of, those illustrated for the tracking device 500. Other components shown in figure 5 can be varied from the illustrative examples shown.
[0074] For example, without limitation, processor 518 can also be configured to receive information identifying the position of aircraft 501 from other aircraft systems 550 inside aircraft 540 501. The information provided by other aircraft systems 550 can be used for reservation, calibration, this, or in comparison with the position of aircraft 501, identified using the satellite navigation system receiver 510.
[0075] Electronic components for the tracking device
500 can be implemented in any appropriate manner using any appropriate hardware or hardware in combination with software. For example, without limitation, processor 518 can be configured to execute instructions for software, which can be loaded or otherwise stored in storage 541. Processor 518 can be a number of processors, a multiprocessor core, or some other type processor, depending on the particular implementation. In addition, the 518 processor can be implemented using a number of homogeneous processor systems, in which a main processor is present with secondary processors in a single chip. As an illustrative example, the 518 processor can be a multiprocessor system
Symmetric 27/39 containing multiple processors of the same type.
[0076] Storage 541 may include memory, persistent storage, or any other appropriate storage devices or various combinations of storage devices. Storage 541 can comprise any piece of hardware that is capable of storing information, such as, for example, without limitation, data, the program code in functional form, and / or other appropriate information or on a temporary basis and / or a permanent basis. Storage 541 can also be referred to as a computer-readable storage device in these examples. Storage 541, in these examples, can be, for example, a random access memory or any other suitable volatile or non-volatile storage device. Storage 541 can take many forms, depending on the particular implementation. For example, storage 541 can be implemented, in whole or in part, as part of processor 518. Alternatively, storage 541 can be implemented entirely separate from processor 518.
[0077] In any case, the instructions for the operating system, applications, and / or programs can be placed in storage 541, which is communicating with processor 518 in any appropriate way. The processes of the different modalities can be performed by the 518 processor using instructions implemented by computer, which can be located in storage 541. These instructions can be referred to as program instructions, program code, program code usable by computer, or code computer-readable program code, which can be read and executed by the 518 processor. The program code in different modes can be incorporated into different physical or computer-readable storage media.
[0078] In these examples, storage 541 may be a / 39 physical or tangible storage device, used to store program code instead of a medium that propagates or transmits program code. In this case, storage 541 can be referred to as a computer-readable tangible storage device or a computer-readable physical storage device. In other words, storage 541 is incorporated into a medium that can be touched by a person.
[0079] Alternatively, the program code can be transferred to the 518 processor using computer-readable signal means. The computer readable signal means can be, for example, a propagated data signal containing program code. For example, the computer readable signal means can be an electromagnetic signal, an optical signal, and / or any other appropriate type of signal. These signals can be transmitted over communications links, such as wireless communications links, fiber optic cable, coaxial cable, a wire, and / or any other appropriate type of communications link. In other words, the communications link and / or the connection can be physical or wireless, in the illustrative examples. In some illustrative embodiments, the program code may be downloaded over a network to the storage 541 of another device or data processing system by means of computer-readable signal means for use in the 518 processor.
[0080] The different modalities can be implemented using any hardware device or system capable of running the program code. As an example, the electronic components for the tracking device 500 may include organic components integrated with inorganic components and / or may be composed entirely of organic components, excluding a human. For example, storage 541 can be composed of an organic semiconductor.
[0081] In another illustrative example, the 518 processor can assume
29/39 the form of a hardware unit that has circuits that are manufactured or configured for a particular use. This type of hardware can perform operations without requiring program code to be loaded into storage 541 to be configured to perform operations.
[0082] For example, when processor 518 takes the form of a hardware unit, processor 518 can be a circuit system, an application specific integrated circuit (ASIC), a programmable logic device, or some other appropriate type of hardware configured to perform a number of operations. With a programmable logic device, the device is configured to perform the number of operations. The device can be reconfigured at a later time or it can be permanently configured to perform the number of operations. Examples of programmable logic devices include a programmable logic arrangement, programmable arrangement logic, a programmable field logic arrangement, a programmable field gate arrangement, and other appropriate hardware devices. With this type of implementation, the program code can be omitted, because the processes for the different modalities are implemented in a hardware unit.
[0083] In yet another illustrative example, the 518 processor can be implemented using a combination of processors found in computers and hardware units. The 518 processor can have a number of hardware units and a number of processors that are configured to run the program code. With this example represented, some of the processors can be implemented in the number of hardware units, while other processors can be implemented in the number of processors.
[0084] Returning to figure 6, an illustration of a process flowchart for using an aircraft alert to perform the search and rescue operation is represented according to a
30/39 illustrative modality. Process 600 can be implemented, for example, in the aircraft operating environment 100 in figure 1 or in the aircraft operating environment 200 in figure 2.
[0085] Process 600 can begin with the registration of an aircraft with a search and rescue system (operation 602). For example, without limitation, operation 602 may include providing appropriate registration information to the search and rescue system so that the search and rescue system can identify what is apparently a transmission from an emergency locator transmitter on the aircraft as a emergency locator transmitter transmission emulated from a different location than that of the aircraft.
[0086] An aircraft tracking device can then generate and send an alert to an aircraft tracking system via a communications satellite (operation 604). An aircraft tracking system can then generate and broadcast an emulated danger radio beacon transmission based on the alert received from the aircraft (operation 606). The emulated danger radio beacon transmission can be received by a search and rescue system and processed by the search and rescue system to determine an appropriate response (operation 608). The search and rescue system can then use appropriate resources to implement the appropriate response (operation 610), with the process terminating afterwards.
[0087] Returning to figure 7, an illustration of a flowchart of a process to provide an aircraft alert for a search and rescue system is represented according to an illustrative modality. For example, without limitation, process 700 can be implemented by the aircraft tracking system 300 in figure 3.
[0088] Process 700 can begin with determining whether an alert, including aircraft identification information and
31/39 position, is received from a tracking device on an aircraft (operation 704). Operation 704 can be repeated until an alert is received from an aircraft.
[0089] When it is determined in operation 704 that an alert is received from an aircraft, the alert can be assessed (operation 706). The assessment of the alert received may include determining whether the alert is a danger alert indicating that the aircraft is in danger (operation 708). When the alert is not a danger alert, appropriate action can be taken (operation 710). In this case, the appropriate action taken in operation 710 does not include alerting a search and rescue system.
[0090] When it is determined in operation 708 that the alert received is a danger alert, an emulated danger radio beacon signal including identification information and position information can be generated (operation 712). The emulated danger radio beacon signal can then be broadcast (operation 714), with the process ending afterwards. [0091] Returning to figure 8, an illustration of a process flow chart for using an aircraft alert to perform the search and rescue operation is represented according to an illustrative modality. The process 800 can be performed, for example, by the search and rescue system 400 in figure 4.
[0092] Process 800 may begin with the reception of a radio beacon transmission of apparent danger through a search and rescue satellite (802 operation). The identification information in the apparent danger radio beacon transmission can be used to identify registration information for the aircraft in a registration database (operation 804). The identified log information can then be used to determine whether the apparent hazard radio beacon transmission is an emulated hazard radio beacon transmission (operation 806). If it is determined in operation 806 that the transmission of
I
32/39 apparent hazard radio is an emulated hazard radio beacon transmission, a calculated position for the transmitter can be compared with information identifying the transmitter position in the registration information (operation 810).
[0093] It can then be determined whether the emulated danger radio beacon transmission is valid (operation 810). If it is determined that the emulated hazard radio beacon transmission is not valid, an indication that the emulated hazard radio beacon is not valid can be provided (operation 812), with the process ending afterwards. If it is determined that the emulated hazard radio beacon transmission is valid, an appropriate response center can be identified (operation 814), the position information for the aircraft can be sent to the appropriate identified response center (operation 816) , and resources can be used by the appropriate response center to implement an appropriate response (operation 818), with the process ending afterwards.
[0094] Returning to figure 9, an illustration of a block diagram of a data processing system, in which several functions can be implemented is represented according to an illustrative modality. In this illustrative example, data processing system 900 includes communications fabric 902. Communications fabric 902 provides communications between processor unit 904, memory 906, persistent storage 908, communications unit 910, communication unit input / output (I / O) 912, and display 914.
[0095] Processor unit 904 serves to execute instructions for software that can be loaded into memory 906. Processor unit 904 can be a number of processors, a multiprocessor core, or some other type of processor, depending on the particular implementation . In addition, processor unit 904 can be implemented using a number of homogeneous processor systems
33/39 in which a main processor is present with secondary processors in a single chip. As an illustrative example, processor unit 904 may be a symmetric multiprocessor system containing multiple processors of the same type.
[0096] Memory 906 and persistent storage 908 are examples of storage devices 916. A storage device is any piece of hardware that is capable of storing information, such as, for example, without limitation, data, the program code in a functional manner, and / or other appropriate information or on a temporary basis and / or a permanent basis. Storage devices 916 can also be referred to as computer-readable storage devices in these examples. Memory 906 can be, for example, a random access memory or any other suitable volatile or non-volatile storage device. Persistent storage 908 can take many forms, depending on the particular implementation, [0097] For example, persistent storage 908 can contain one or more components or devices. For example, the 908 persistent storage can be a hard drive, a USB memory, a rewritable optical disc, a rewritable magnetic tape, or some combination of the above. The media used by the 908 persistent storage can also be removable. For example, a removable hard drive can be used for 908 persistent storage.
[0098] The communications unit 910, in these examples, provides communications with other data processing systems or devices. In these examples, the 910 communications unit is a network interface card. The 910 communications unit can provide communications using either one or both physical and wireless communications links.
[0099] The 912 input / output unit allows input and output of
34/39 data with other devices that can be connected to the 900 data processing system. For example, the input / output unit 912 can provide a connection for user input via a keyboard, a mouse, and / or some another appropriate input device. In addition, the 912 input / output unit can output to a printer. Display 914 provides a mechanism for displaying information to a user.
[00100] Instructions for the operating system, applications, and / or programs can be located on storage devices 916, which are in communication with processor unit 904 through communications fabric 902. In these illustrative examples, the instructions are in a functional form in the 908 persistent storage. These instructions can be loaded into memory 906 for execution by the 904 processor unit. The processes of the different modes can be performed by the 904 processor unit using the instructions implemented by the computer, which can be located at a memory, as in memory 906.
[00101] These instructions are referred to as program instructions, program code, computer-usable program code, or computer-readable program code, which can be read and executed by a processor on processor unit 904. The program code in different modalities it can be incorporated in different physical or computer readable storage media 924, such as in memory 906 or persistent storage 908.
[00102] Program code 918 is located in a functional form in the computer-readable medium 920, which is selectively removable and can be loaded into, or transferred to, the data processing system 900 for execution by processor unit 904. Program code 918 and computer-readable media 920 form computer program product 922 in these examples. In one example, computer-readable media / 39 920 may be computer-readable storage medium 924 or computer-readable signal media 926.
[00103] Computer readable storage medium 924 may include, for example, an optical or magnetic disk that is inserted or placed in a drive or other device that is part of the persistent storage 908 to transfer to a storage device, such as a hard drive, which is part of the 908 persistent storage. The 924 computer-readable storage medium can also take the form of persistent storage, such as a hard drive, a Pen Drive, or a USB memory, which is connected to the system data processing 900. In some cases, the computer readable storage medium 924 may not be removable from the data processing system 900.
[00104] In these examples, the computer-readable storage medium 924 is a physical or tangible storage device used to store program code 918 instead of a medium that propagates or transmits program code 918. The computer-readable storage medium Computer 924 is also referred to as a computer-readable tangible storage device or a computer-readable physical storage device. In other words, the computer-readable storage medium 924 is a medium that can be touched by a person. [00105] Alternatively, program code 918 can be transferred to data processing system 900 using computer readable signal means 926. Computer readable signal means 926 can be, for example, a propagated data signal containing program code 918. For example, computer readable signal means 926 can be an electromagnetic signal, an optical signal, and / or any other appropriate type of signal. These signals can be transmitted over communications links, such as wireless communications links, fiber cable
36/39 optics, coaxial cable, a wire, and / or any other appropriate type of communications link. In other words, the communications link and / or the connection can be physical or wireless in the illustrative examples.
[00106] In some illustrative modalities, the program code
918 can be downloaded over a network for persistent storage 908 from another data processing device or system via computer-readable signal means 926 for use in data processing system 900. For example, the program code stored in a computer-readable storage medium in a server data processing system can be downloaded over a server network to the data processing system 900. The data processing system providing program code 918 can be a computer server, a client computer, or some other device capable of storing and transmitting program code 918.
[00107] The different components illustrated for the 900 data processing system are not intended to provide architectural limitations to the way in which different modalities can be implemented. The different illustrative modalities can be implemented in a data processing system including components in addition to, or in place of, those illustrated for the 900 data processing system. Other components shown in figure 9 can be varied from the illustrative examples shown. The different modalities can be implemented using any device or hardware system capable of running the program code. As an example, the data processing system may include organic components integrated with inorganic components and / or may be composed entirely of organic components, excluding a human being. For example, a storage device can be composed of an organic semiconductor.
37/39 [00108] In another illustrative example, processor unit 904 may take the form of a hardware unit that has circuits that are manufactured or configured for a particular use. This type of hardware can perform operations without requiring program code to be loaded into the memory of a storage device to be configured to perform operations.
[00109] For example, when processor unit 904 takes the form of a hardware unit, processor unit 904 can be a circuit system, an application specific integrated circuit (ASIC), a programmable logic device, or some another appropriate type of hardware configured to perform a number of operations. With a programmable logic device, the device is configured to perform the number of operations. The device can be reconfigured at a later time or it can be permanently configured to perform the number of operations. Examples of programmable logic devices include, for example, a programmable logic arrangement, programmable arrangement logic, a programmable field logic arrangement, a programmable field gate arrangement, and other appropriate hardware devices. With this type of implementation, program code 918 can be omitted, because the processes for the different modalities are implemented in a hardware unit.
[00110] In yet another illustrative example, the processor unit
904 can be implemented using a combination of processors found in computers and hardware units. Processor unit 904 can have a number of hardware units and a number of processors that are configured to run program code 918. With this example represented, some of the processors can be implemented in the number of hardware units, while other processors can be implemented in the number of processors.
38/39 [00111] In another example, a bus system can be used to implement communications fabric 902 and can be composed of one or more buses, such as a system bus or an input / output bus. Naturally, the bus system can be implemented using any appropriate type of architecture that provides a transfer of data between the different components or devices attached to the bus system.
[00112] Additionally, the communications unit 910 may include a number of devices that transmit data, receive data, or transmit and receive data. The communications unit 910 can be, for example, a modem or a network adapter, two network adapters, or some combination thereof. In addition, a memory may be, for example, memory 906, or a cache, such as those found in an interface and memory controller hub that may be present in the 902 communications fabric.
[00113] Flowcharts and block diagrams in the different modalities represented illustrate the architecture, functionality, and operation of some possible implementations of devices and methods in the illustrative modalities. In this regard, each block in the flowcharts or block diagrams can represent a module, segment, function, and / or a portion of an operation or step. For example, one or more of the blocks can be implemented as program code, in hardware, or a combination of program code and hardware. When implemented in hardware, the hardware can, for example, take the form of integrated circuits that are manufactured or configured to perform one or more operations in flowcharts or block diagrams.
[00114] In some alternative implementations of an illustrative modality, the function or functions noted in the blocks may occur out of the order shown in the figures. For example, in some cases, two blocks
39/39 shown in succession can be executed substantially simultaneously, or the blocks can sometimes be performed in reverse order, depending on the functionality involved. Also, other blocks can be added in addition to the blocks illustrated in a flow chart or block diagram.
[00115] The description of the different illustrative modalities has been presented for purposes of illustration and description, and is not intended to be exhaustive or limit the modalities in the manner described. Many modifications and variations will be apparent to those of ordinary skill in the art. In addition, different illustrative modalities can provide different benefits compared to other illustrative modalities. The selected modality or modalities are chosen and described in order to better explain the principles of the modalities, the practical application, and to allow others of common knowledge in the art to understand the invention for various modalities with various modifications when they are appropriate for use. particular contemplated.
