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。

Abstract:

Based on analysing the principle of the Least Squares(LS) algorithm, a new dyn amic calibration of attitude error for inertial navigation system(INS) based on the R ecursive Least Squares(RLS) algorithm is presented, and a new model is proposed. Simu lation results shows that this method can improve the estimation precision and e fficiency, the course error is less than 3.5″, and the horizontal attitude erro r is less than 0.15″. It can solve the problem of realtime calibration of a ttitude error for INS in dynamic condition. It can also improv e the attitude measurement precision of INS and the exterior ballistic measure ment precision of the space tracking, telemeteri ng and command(TT&C) ship.
