Firstly,the working principle of electronic magnetic compass was analyzed to study the effects of magnetic compass inclination measurement error on the heading angle measurement accuracy.Then,aphysical model of dual-axis acceleration sensor measuring the inclination was built,and the corresponding mathematical model was established,to complete the compensation for angle measurement errors.The results show that the inclination angle compensation algorithm of electronic magnetic compass can effectively improve the measurement accuracy of the heading angle.
