摘要
本文研究了捷联惯导系统姿态更新的旋转矢量算法,并以圆锥运动为条件,对旋转矢量算法进行了优化和仿真,分析了锥运动环境下数学平台的算法漂移。
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.
