摘要：
The fiber optic gyro (FOG) strapdown inertial navigation system (SINS) is researched. Auto-regressive moving average (ARMA) model is built for modeling stochastic errors in FOG by using time series analysis method. The FOG stochastic model is realized in SINS self-alignment. Real-time filtering of FOG stochastic error is realized in the process of SINS gyrocompass self-alignment. The prototype test results show that the proposed method can effectively improve the accuracy of FOG SINS gyrocompass self-alignment. ©, 2015, Northeast University. All right reserved.
