Abstract :
In order to improve the accuracy of strapdown inertial navigation system, this paper brought the rotation monitor technique to improve the SINS accuracy. Three schemes were analyzed respectively toward the modulation results of constant gyro drift and the gyro scale error. The new scheme is given by analyzing in this way. Computer simulation shows that the new scheme can modulate the inertial sensor error effectively and improve the position accuracy of SINS greatly.
