Magnetometer calibration or setting

An aspect of the invention relates to a method for correcting magnetometric measurements (10) made by a magnetometer mounted on a mobile support. The mobile support carries one or more movement and/or position sensors fixedly mounted with respect to the magnetometer. The method comprises:obtaining magnetometric measurements (12) and movement and/or position measurements (14, 16) made simultaneously by the magnetometers, respectively the movement and/or position sensors during a time interval;inferring, by a processing unit, corrected magnetometric measurements (28) on the basis of the magnetometric measurements (12) and the movement and/or position measurements (14, 16) made simultaneously during the time interval and in which method the processing unit (36) comprises one or more microprocessors and is capable of inferring the corrected magnetometric measurements (28) via an artificial intelligence algorithm (24), said algorithm being trained by means of training data, to find a correction for the magnetometric measurements according to the log of magnetometric measurements as well as movement and/or position measurements recorded during the time interval.
