摘要

The acceleration interference and external magnetic field interference will seriously affect the accuracy of the magnetic compass. In order to solve the above problem, this paper presents anti-interference measurement method of magnetic compass based on auxiliary gyroscope. The system filter equations were composed by magnetic compass attitude quaternion differential equations and the sensor error models, and the attitude of magnetic compass was estimated by adaptive Kalman filter. Finally, the semi-physical experiments have carried on by non magnetic turntable. The results show that the method can effectively estimate the attitude of magnetic compass in the magnetic interference and acceleration interference environment. Moreover, the measurement precision of magnetic compass can be improved.
