Abstract:

Rotating strapdown inertial navigation system (RINS) can modulate the gyro and accelerometer error with error rotating compensation method to improve the precision. The error model of the SINS and the mechanism of the error rotating compensation were analyzed in this paper. Based on analysis and simulation of several typical IMU rotating modulation schemes, the validity of the error rotating compensation technology was proved and the characteristic of the rotating schemes were compared.
