System and Method for Performing a Background Calibration for a Magnetometer

A method and system are provided for performing a background calibration of a magnetometer. The method comprises obtaining a plurality of magnetometer readings; applying an active set of calibration parameters to the plurality of magnetometer readings to obtain a plurality of values; applying a new set of calibration parameters to the plurality of magnetometer readings to obtain a plurality of further values; applying an active set of calibration parameters to the plurality of magnetometer readings to obtain a plurality of further values; and replacing the active set of calibration parameters with the new set of calibration parameters when a quality of the plurality of values is higher than a quality of the further values.
