Paper Abstract

Initial alignment is one of the most prominent and vital issues in fiber-optic gyro strapdown inertial navigation systems (SINS). In most research, the standard Kalman filter (KF) and its various versions have been used to accomplish the initial alignment of SINSs. A robust alignment approach is presented based on a generalized proportional–integral–derivative filter. The proposed inertial frame-based alignment approach outperforms the standard KF-based alignment methods and achieves a robust and accurate solution for marine fiber-optic SISN alignment. Experimental results also verify the prominent performance of the presented approach compared to the conventional standard KF-based alignment method.
