Paper Abstract

In order to solve the problem of non-orthogonality of triaxial magnetometer, we propose a rotation compensation method based on cosine magnetic field to calibrate triaxial magnetometer, which is convenient for practical application. The simulation results show that the error difference with the preset angle is no more than 36′′ (one percent degree), and the error accuracy is very high and we have carried out experiments, the results show that the correct method is feasible and effective, through non-orthogonal compensation, the accuracy of magnetometer measurement has been significantly improved.
