Abstract :
The rotation method of the rotary inertial navigation system contains rotating and static states. The rotary angular rate changes all the time. The changing rotary angular rate has an impact on the inertial measurement errors self-compensation. This paper focuses on the rotary SINS accuracy influenced by the rotary angular rate and acceleration. The relationship between the system positioning accuracy and rotating angular rate is deduced from theory concerning the IMU rotary error model. The correctness of the analysis result is verified by simulation. At last, the optimal value of the rotating angular rate, as well as the acceleration, are figured out.
