Method and apparatus for compensation of the errors of the signals of the course of a magnetic sensor azimuth

摘要

P the invention relates to an apparatus for the calibration of a magnetic detector of the azimuth. / p & & p & an electromagnetic sensor 10 with a gyromagnetic device uses the gyroscope 13 of the compass to the formation of references of course, to which the output signals of the electromagnetic sensor 10 are compared in a circuit 12 so that the data of errors cardinal and intermediate are formed and allow the creation of compensation signals. The references of course, are compensated for the drift of the gyroscope. The calibration is carried out by the orientation of the aircraft to several caps. / p & & p & application to the calibration of the detectors of the azimuth of the aircraft. / p
