Abstract： Installation error angle is one of the factors that affect the accuracy of electronic compass used for geomagnetic navigation. To solve this problem, the calibration and compensation methods for installation error angle are studied. By analyzing the generation mechanism of installation error angle of electronic compass, an installation error model is established, compensation formulae are derived, and calibration scheme is proposed. To verify the correctness of the calibration and compensation methods, the verification experiment is conducted by computer simulation. The simulation results show that the proposed calibration and compensation methods are effective and practical.
