Abstract :
In this paper, a new attitude corrected algorithm based on conjugate gradient method is proposed, which is applied to the combination of accelerometers and a three axes magnetometer, and its principle is given, and the simulation of a rapidly rotating projectile´s attitude test is done by using this method. The simulation results indicate that the algorithm can suppress the growth of errors effectively and meet the requirements of accuracy.
