A New Air Data Attitude and Heading Reference System Algorithm Applied to High-dynamic Guidance Flight

To promote the availability of attitude and heading reference system(AHRS)for high dynamic guidance flight,a new algorithm of ADAHRS(air data AHRS) based on self-adaptive Kalman filter was presented,the air data was used to eliminate the movement acceleration from the measurement,and the problem of attitude correction and heading in high-dynamic guidance flight was solved.The algorithm is designed and applied to MEMS system.The result of vehicle-borne proves that the algorithm is reasonable,feasible and robust to be applied to missile or aircraft with high maneuver.
