Application for solving angular velocity with adaptive kalman filtering in GFSINS

摘要

Based on a nine-accelerometer configuration, detailed analyzes the principle of gyroscope free strapdown inertial navigation system (GFSINS), and gives the process for solving angular velocity using a nine-accelerometer configuration. Adaptive kalman filter is constructed equation of state and filtering equations, and using a ballistic data, in the external noise is white noise conditions, and the adaptive kalman filter is verified with high precision solver.
