Abstract

In order to measure attitude angle for projectile with small caliber and high rotational speed, the attitude algorithm was presented based on pure geomagnetic information. Through building attitude transformation matrix with reference to the relation of coordinated system, the mathematic model of attitude angle was established, and corresponding pure attitude algorithm was designed. The magnetic field model was simulated for tri-axial geomagnetic information, and was computed by this attitude algorithm in sequence. The result shows that this attitude algorithm has higher long-term precision. It can be used for attitude control system in some type of rolling projectile.

Key words： geomagnetic sensor; attitude angle; roll projectile; attitude algorithm
