摘　　要：针对常规自对准中数据挖掘不充分问题,提出了一种基于逆向导航的捷联自对准方法。该方法首先对粗对准阶段的惯组数据进行存储,然后利用逆向导航算法,实现了存储数据的二次利用,最后采用卡尔曼滤波完成精对准。仿真表明,与常规自对准方法相比,新方法提高了惯组数据的利用率,缩短了对准时间。In order to solve the insufficiency of SINS data in initial alignment,a SINS self-alignment technology based on reverse navigation algorithm is proposed,in which the SINS data sampled in coarse alignment is saved and then is used for fine alignment by reverse navigation. The simulation result shows the efficiency of SINS data is improved by using the new technology and the alignment time is reduced by comparing with regular method.
