METHOD AND DEVICE FOR SIMULTANEOUS IDENTIFICATION AND CORRECTION OF ERRORS IN MEASUREMENTS OF A MAGNETOMETER

摘要

The present invention relates to a method and a device (1) for correcting measurement errors of a magnetometer (2) mounted on a vehicle (3). BR/ we define a theoretical correction model: BR/ (CF DRAWING IN BOPI) BR/ in which [A], [C] i and Hp are elements to be determined, Hm is the measured field, H is the effective field and [M] a transformation matrix; BR/ - we define a vector error: BR/ (CF DRAWING IN BOPI) BR/ - we determine the square of the error thus defined; and BR/ - we identify the model coefficients that minimize the sum of the squares of the error modules, for all the measurements made. / P
