ABSTRACT:
A three winding induction compass mounted in a host vehicle has each winding output coupled to an analog to digital converter. Each winding output is weighted and accumulated by a push down stack circuit to obtain a time filtered output and the maximum and minimum values of each filtered output are determined and stored as the vehicle is turned in a 360.degree. circle. The distortions due to the permanent and induced magnetism of the host vehicle and due to winding imbalance between the three windings and misorientation of the three windings are obtained from the maximum and minimum values to obtain calibration parameters. The calibration parameters for the windings are applied to the outputs of the three windings to obtain an equivalent two winding output which is normalized for determining the corrected compass heading.
