摘　　要：姿态更新是SINS的核心内容,而速度更新又是姿态更新的重要内容,因此高精度的划桨误差补偿算法是时时刻刻研究的热点。利用圆锥误差补偿采用前一周期陀螺输出角增量的算法,提出一种采用前一周期速度增量和角增量的改进三子样划桨误差补偿算法,与传统算法进行比较,具有更高的精度。Attitude update is the core content of SINS,and velocity update is the important content of attitude update,so the high-precision sculling error compensation algorithm is a hot research topic all the time. By using the coning error compensation and the algorithm of the gyro output angle increment in the previous cycle, an improved three-sample sculling error compensation algorithm based on the previous cycle speed increment and angular increment is proposed. Compared with the traditional algorithm, it has higher precision.
