Abstract

According to the accumulation characteristic of SINS positioning error caused by inertial sensor error, this paper brought the rotation monitor technique to improve the SINS accuracy. Dual-axis consequential rotation scheme is designed by deeply analyze toward the existing single-axis and two-axis scheme. This scheme is selected as the final scheme by analyzing modulation results of constant gyro drift, the gyro scale error and the deviation of the gyro installation error. Computer simulation shows that this scheme has better modulation than single-axis and two-axis continuous scheme and can improve position accuracy of SINS effectively.
