Optimization of the Rotation Vector Algorithm for Strapdown Inertial Navigation System Attitude Updating

Yi Li

Abstract

The attitude updating algorithm is a determinant factor in the strapdown inertial navigation system(SINS).This paper studies the rotation vector algorithm,discusses the improved algorithms under the coning base motion,performs a numerical simulation,and analyses the algorithm drifts of the mathematical platform caused by the base coning motion as well in detail.
