The Solution Method for Attitude Measurement of Projectile and Rocket

In order to test the attitude of the small projectile and rocket, a combined measurement system of geomagnetic sensor and gyroscopic sensor is used. According to the characteristics of geomagnetic sensor and gyro sensor, kalman filter algorithm is put forward to complete the measurement of projectile body attitude, and the simulation is carried out. The simulation results show that the method can effectively suppress the attitude error of gyroscope accumulates with time caused by zero drift, and improve the attitude calculation precision. This paper proves that the solution method can be reliably used for the real-time attitude measurement of the small projectile and rocket on some condition.
