Magnetometer calibration or setting

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 position measurements made simultaneously by the magnetometers, respectively the movement and/or position sensor during a time interval;
• and
• inferring, by processing circuitry, corrected magnetometric measurements on the basis of the magnetometric measurements and the movement and/or position measurements made simultaneously during said time interval and in which method the processing circuitry comprises one or more microprocessors and is configured to infer the corrected magnetometric measurements via an artificial intelligence algorithm, 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.

A mobile terminal, comprising:

• a magnetometer,
• one or more movement and/or position sensors fixedly mounted with respect to the magnetometer, and
• processing circuitry connected to the magnetometer and to the movement and/or position sensors to obtain magnetometric measurements and movement and/or position measurements made simultaneously by the magnetometer, respectively the movement and/or position sensors during a time interval, wherein the processing circuitry is configured, by means of a computer program, to infer corrected magnetometric measurements on the basis of the magnetometric measurements and movement and/or position measurements made simultaneously during said time interval.
