Abstract

The disclosure herein describes methods and apparatuses for magnetometer calibration through collection and processing of calibration data in the background and unassisted autonomous calibration maneuvers prior to a mission. As an autonomous or semi-autonomous vehicle is transported by the user after power up, vehicle data relevant to magnetometer calibration can be collected from the movements of the vehicle. Magnetometer calibration accuracy checks or some parts of magnetometer calibration can be performed from the data collected in the background. Based on the extent of accuracy determinations, the vehicle can further perform autonomous and unassisted maneuvers to complete magnetometer calibration before performing a mission.
