摘要
文中针对工程实际中陀螺输出的角速率形式,研究了锥运动条件下捷联惯导系统姿态计算中旋转矢量双子样、三子样法和四元数法,并提出了一种改进双子样法,对各算法的漂移误差进行了仿真分析。仿真结果表明在角速率输入情况下改进双子样法的精度优于其他算法,是一种较理想的高精度捷联航姿算法。
The attitude updating algorithm is a determinant factor in strapdown inertial navigation system （SINS）. According to the practical projects, this paper studies two-sample, three-sample rotation vector and quaternion under the coning base motion, and an improved two-sample rotation vector algorithm is provided. The simulation results show that the accuracy of the improved two-sample rotation vector algorithm is better than that of other algorithms.
