    5 OBJECT OF THE INVENTION
    The present invention relates to an apparent wind sensor for boats, which can be used mainly in sailboats, and which offers filtered, corrected and compensated data based on rocking, pitching and yaw of course movements, such as
    10 correction of the tilt and seat tilt plane.
    BACKGROUND OF THE INVENTION
    In the early 80's electronic instruments and nautical navigation systems
    15 electronics became popular. In many respects, the history of electronic instruments and navigation software is the history of the Copa América, since most of the main evolutions were driven by the needs of this competition.
    One of these electronic instruments is the MHU (master head unit) wind sensor. This
    20 instrument is normally used in maritime sports navigation applications to determine apparent wind conditions. The MHU wind sensor is a fundamental part of a sailing navigation system, and measures the direction and speed of apparent wind, which is the result of real wind on the moving vessel. It consists of an anemometer and a weather vane mounted on a structure, by which the sensor is installed
    25 in the bow area or on the mast of a sailboat, usually by using a hanger
    or extension to avoid the disturbances produced by the influence of the candle.
    At present there are numerous technologies to accurately measure wind direction and intensity, such as sonic wind sensors, laser doppler, Pitot tube, etc., but 30 such precise technologies are not embarking on them because of their excessive weight, size, consumption and dynamic behavior For this reason the MHU sensors currently used continue to use a classic design, consisting of a bowl anemometer and a wind vane - there are also some models of windlasses but less extended in the field of competition -, which do not take into account movements of inclination and pitch of the boat that distort the readings, since they produce variations of both the speed and the


    orientation of the wind on the sensor.
    DESCRIPTION OF THE INVENTION
    The apparent wind sensor for boats of the invention has a configuration that solves the technical problem posed, since it implements means to be able to offer readings of the apparent wind speed and direction filtered, corrected and compensated according to the balancing movements, nodding and yaw of course, with correction of the tilt plane and seat of the boat. The sensor is the type that they understand
    10 a structure in which an anemometer - preferably of cups - and a weather vane are mounted, and is usually installed on the bow or top of a sailboat mast through its structure and an extension hanger.
    According to the invention, the sensor comprises a plurality of sensors for
    15 provide input signals comprising: -a speedometer of the anemometer, -a vane orientation sensor, -a 3-axis gyroscope, and -a 3-axis accelerometer,
    20 further comprising an electronic controller for processing the input signals with correction, filtering and compensation of data based on the instantaneous movements, inclination and seating of the vessel, provided with an output interface of at least the speed and speed data. Apparent wind orientation corrected and filtered.
    25 The implementation of the gyroscope, accelerometer and processor allows instantaneous corrections and compensations to be applied to the signals coming from the anemometer's rotation speed sensors, according to the movements experienced by the sensor due to instantaneous inclination variations and the pitch of the sensor. boat –wheel waves and wind maneuvers or gusts-, offering filtered and purified data from the exit
    30 real parameters of the apparent wind, optimizing the decision of the boat skipper or helmsman for the best use of real wind conditions.

    (3) and the weather vane (4) as said-; while the arrays (21) of hall probes (and the chipset (22) thereof) are arranged in auxiliary plates (25) perpendicular to the axes (23) of the anemometer (3) and of the vane (4) and in extreme positions inside the housing (2a); by means of the inside of the housing (2a) means - such as grooves, not shown - of exact insertion of the main electronic board (24) and having tongue and groove (26) between the main electronic board (24) and the auxiliary plates (25) for the exact positioning of said auxiliary plates (25).
