Paper Abstract

Alignment of carrier-based aircraft inertial navigation system (slave inertial navigation system, SINS for short) on moving carrier needs velocity and attitude information from carrier inertial navigation system (MINS). If velocity and angular rate of the carrier are compensated, SINS alignment will be the same to static alignment. However, acceleration quantization in MINS will cause velocity error, which will influence the rapidity and accuracy of SINS alignment. This paper analyzes the influence of acceleration quantization error on SINS rapid alignment. Numerical simulations are performed, and the results show that if the quantization frequency of MINS accelerator is 24 KHz, and the correspondent alignment error of SINS is within 0.003° / h, the alignment time can not be less than 300s.
