摘要
本文首先阐述了卡尔曼滤波技术的简单理论,然后建立了捷联惯性导航系统初始对准的卡尔曼滤波模型,并对静基座下的卡尔曼滤波初始对准精度进行分析,最后进行了卡尔曼滤波仿真。仿真结果表明,此方法算法简单,能有效缩短初始对准时间,对准稳态精度较高,是一种可靠的初始对准方案。
This paper describes the simple theory of Calman filtering technology, and then established the Calman filter model of initial alignment of strapdown inertial navigation system, and Calman filter to initial static base alignment accuracy is analyzed, finally the simulation of Calman filter. The simulation results show that the algo-rithm is simple and can effectively shorten the initial alignment time, and the alignment steady state precision is high. It is a reliable initial alignment scheme.
