Vehicle interferential magnetic field is a main factor affecting measurement of magnetometer in geomagnetic navigation. In this paper, a vehicle's magnetic field compensation algorithm was presented, generation mechanism of vehicle's magnetic field distribution was analyzed, and compensation model was rebuilt. Finally, the 152 mm spin-projectile was selected as the research object, and the method of magnetic field compensation was simulated and analyzed. Simulations demonstrate that the estimator can effectively estimate error parameters of magnetic interference. Moreover, online compensation significantly enhances performance of magnetometer.
