摘要
在分析最小二乘算法原理的基础上,提出了一种基于递推最小二乘算法的惯导姿态误差动态标定方法,建立了计算模型,进行了仿真分析。仿真结果表明,该方法具有较高的解算精度和计算效率,航向误差解算精度优于3.5″,水平误差解算精度优于0.15″。该方法解决了动态条件下惯导姿态误差实时标定的技术难题,对提高惯导姿态测量精度和测量船外测精度具有重要意义。
Based on analysing the principle of the Least Squares（I.S） algorithm, a new dynamic calibration of at- titude error for inertial navigation system（INS） based on the Recursive Least Squares（RLS） algorithm is present- ed, and a new model is proposed. Simulation results shows that this method can improve the estimation precision and efficiency, the course error is less than 3.5＂, and the horizontal attitude error is less than 0.15＂. It can solve the problem of real-time calibration of attitude error for INS in dynamic condition. It can also improve the attitude t precision of INS and the exterior ballistic measurement precision of the space tracking, telemetering and command（rIT＆C） ship
