【摘要】 从工程实用角度出发,提出了一种在初始方位已知的情况下同时进行姿态估计和仪表误差标定的迭代计算方法。半实物仿真结果表明:该方法在占用一定初始对准时间的条件下能在线补偿仪表误差,并能显著提高惯导系统导航精度,效率较高。更多还原

【Abstract】 From the view of engineering utility, this paper presents an iteration algorithm of calibrating initial attitude and instrument抯 errors at the same time as initial heading is given. Result of semi-physical simulation indicates that this algorithm can real-time compensate instrument抯 errors when using some time of the initial alignment. It can also evidently increase the navigation accuracy of SINS, and has higher efficiency.更多还原
