ABSTRACT:
A direction detecting system comprises a geomagnetic field sensor for detecting the direction of the earth magnetism by two perpendicular components and a computing circuit for computing a direction and producing a direction signal from the electrical signals associated with the two perpendicular components from the geomagnetic field sensor. The computing circuit detects maximum values of distortions according to the distortion characteristics of the electrical signals associated with the two perpendicular components from the geomagnetic field sensor. Distortion amounts are computed and stored by the maximum distortion values and are used to correct the electrical signals from the geomagnetic field sensor.
