This paper proposes a correction method concerning the inclination error and non-horizontal error of magnetic compass when magnetic compass is vibrated. This system used the 2-axis variable resistance and pendulum. A pendulum hanging from the 2-axis variable resistance of this system is always maintain the horizontal because of gravity. but these data had some intrinsic error. So we used the low pass filter to solve this problem. So this system can get the accurate azimuth of magnetic compass. In conclusion, These results demonstrate convincingly by applied algorithm of experiment.
