Compensation of Hard- and Soft-Iron distortions is magnetometer measurment data

This article presents compensation methods of the adverse effect of soft and hard ferromagnetics on MEMS magnetometers indications. The tilts compensation method, for the data obtained from this type of inertial sensors, is thoroughly presented. The technique of the yaw angle and the influence of ferromagnetic distortions on the value of its estimation are discussed. The calibration procedure and the ferromagnetic influence on the distribution of recorded measurement data are described in detail. Finally, the method of coefficients compensation for simultaneous Hard- and Soft-Iron distortions is presented.
