Researching on the compensation technology of rotating mechanism error in single-axis rotation strapdown inertial navigation system

In order to satisfy the requirement of attitude accuracy in high precision single-axis rotation SINS and avoid influence on the system by tilt angle in level of rotating mechanism, the method of estimation and measurement at the different positions is proposed. The tilt angles are estimated by summing different transformation matrixes, which are calculated from the measured values of gyros by placing the rotating mechanism at multi-group symmetric positions. The feasibility of this method is verified by simulation, and the experiment is operated by the FOG SINS which is made by our lab. The result shows that the method is valid and feasible.
