Abstract
When space homing aerocraft long term flighting on orbit, the accuracy and rapidity of its attitude and orientation are the key factors for its combat effectiveness and survivability. Fiber optic gyro is suitable for the navigation requirements of space vehicles, but in the long run, it is necessary to calibrate the fog. Aiming at the problem, A self calibration method based on fusion filter is presented. According to the observation of the star sensor, the gyro drift and the four part number vector of the attitude are used as the state estimation by UKF. The gyro axis misalignment error and scale factor error are used as the model error to be estimated by the prediction filter. This method can guarantee the precision, decrease the computation and improve the algorithm speed.
