1. A method for correcting magnetometric measurements made by a magnetometer mounted on a mobile support, the mobile support carrying, in addition to the magnetometer, one or more movement and/or position sensors fixedly mounted with respect to the magnetometer, the method comprising:
obtaining magnetometric measurements and movement and/or position measurements made simultaneously by the magnetometer and the one or more movement and/or position sensors, respectively, during a time interval;
determining a direction from the obtained magnetometric measurements;
calculating, by processing circuitry, a correction amount based on the magnetometric measurements and the movement and/or position measurements made simultaneously during said time interval, wherein the calculating step further comprises calculating the correction amount via an artificial intelligence algorithm, said algorithm being trained, using training data, to determine the correction amount from inputs of a log of magnetometric measurements and the movement and/or position measurements obtained during the time interval; and
determining a corrected direction by adding the calculated correction amount to the determined direction.
