Abstract
A new algorithm based on inertial frame was introduced in coarse alignment for SINS to reduce the azimuth error. In accurate alignment, an algorithm based on closed loop feedback system was used to reduce the position error caused by the second short stop and the azimuth error in coarse alignment. The results of aligning experiments show that the alignment algorithm with above-mentioned algorithms can reduce position error, and improve the alignment accuracy for SINS. It has a wide application prospect.
