Abstract
Since strap-down inertial navigation system (SINS) opening loop alignment has some problems on calculating the cosine matrix between body frame and navigation frame, a closed-loop alignment algorithm based on computer control has been introduced. Using navigation algorithm to simulate navigation frame, the cosine matrix between body frame and navigation frame is figuring out. The result demonstrates that the new alignment algorithm is simple and effective, which has an important reference significance on SINS alignment.
