This paper presents an efficient tilt compensation algorithm for the low cost two-axis magnetic compass. The general magnetic compass module consists of a three-axis magnetic compass and a two-axis inclinometer to calculate tilt-compensated azimuth information. In the interest of reducing the cost, a two-axis magnetic compass with a two-axis accelerometer is developed in this paper. The third-axis data of the magnetic compass is estimated using earth magnetic field information. The tilt-induced-error is compensated using the estimated data and measurement data. Results of experiment show that this algorithm can be used to realize tilt-compensation for 2-axis magnetic compass.
