ABSTRACT:
The method and system described herein calls for the calibration of an electronic compass without using the operator of the vehicle in the process. This eliminates the need for the operator of the vehicle to help to supply information relating to the earth's unknown magnetic field as sensed from the frame of reference of the vehicle in which the electronic compass resides. The method does not need to make use of the unknown magnetic field due to the earth (as sensed from the frame of reference of the vehicle in which the electronic compass resides) in the process of automatically calibrating the compass. This magnetic field, although unknown, is utilized by viewing the position of the vehicle with respect to the earth's field, thereby eliminating the effect on the compass computation of the earth's magnetic field as sensed in the vehicle.
