Abstract:

In order to solve the problem of pitch angle calculation, this paper studies algorithm of the projectile’s pitch an- gle using geomagnetic sensor. Based on the analysis of the algorithm, the principle equation for calculating pitch angle with geomag- netic sensor is studied, and the simulation and physical experiments are carried out. The test results show that the method of geo- magnetic sensor can be used to measure the attitude pitch angle of the rotating projectile, which effectively restrains the errors and has high practical values.
