<p>PROBLEM TO BE SOLVED: To provide a magnetometer dispensing with a compensating flight for making special motion for determining a compensating factor and having a large compensating effect of magnetic noise even when there exists a magnetic noise caused by vibration of an aircraft. SOLUTION: This magnetometer is provided with a triaxial vector magnetic sensor A and a triaxial vector magnetic sensor B for detecting geomagnetism, a triaxial vector synthesizer for calculating a scholar magnetic field value, a magnetic compensating factor estimator by system identification for estimating a magnetic compensating factor by the system identification from the output of the triaxial vector synthesizer and the output of the triaxial vector magnetic sensor B and a magnetic compensator by the system identification for outputting intensity of a magnetic field of the geomagnetism by performing magnetic compensation by the system identification from the output of the magnetic compensating factor estimator by the system identification, the output of the triaxial vector synthesizer and the output of the triaxial vector magnetic sensor B.</p> |
