サーと各センサーの出力を比較処理する装置を備
え、局地的な異常磁界による方位測定に対する障
害の有無を判定し、異常磁界が有る場合に方位測
定に精度が得られないことを表示することを特徴
とする異常磁界検出装置付方位測定装置。 A device that measures direction is equipped with a device that compares and processes the output of multiple direction sensors and each sensor, and determines whether or not there is an obstacle to direction measurement due to a local abnormal magnetic field, and if there is an abnormal magnetic field, it is equipped with a device that compares and processes the output of each sensor. An azimuth measuring device with an abnormal magnetic field detection device characterized by displaying that accuracy cannot be obtained.
