Research on Acceleration Transformation Algorithm of Ship's Strapdown Inertial Navigation System

本文提出了一种基于等效旋转矢量算法的比力递推转换方法 ,该方法在不增加计算量的情况下 ,提高了比力转换精度 ,适用于船舶动态情况下的捷联惯导系统。

The acceleration recursive transformation algorithm based upon the rotation rector attitude algorithm is presented in this paper,which improves the acceleration transformation precision without increasing the computation burden.The algorithm is specially applicable to ship's strapdown inertial navigation system under dynamic circumstance.
