AZIMUTH DETECTOR, AND AZIMUTH DETECTING METHOD

摘要

PROBLEM TO BE SOLVED: To eliminate inconvenient complexity of rotating an azimuth detector for calibration in order to detect a correct azimuth. SOLUTION: Difference values corresponding to an azimuthθof an inductance in a conductor line in respective flowing directions of a direct current are found by switching positively and negatively the directions of the direct current for a magnetic bias flowing in the conductor line of a magnetic detecting element. The azimuth is found by arctangent computation of the two difference values in the magnetic detecting elements. COPYRIGHT: (C)2005,JPO&NCIPI
