2.A New Method of Autonomous Celestial Navigation for Lunar Rover and Analysis of Precision
一种基于UPF的月球车自主天文导航方法收藏指正
3.Through analyzing several common integrated navigation systems,the navigation method for hypersonic cruise air vehicles were put forward by adopting strapdown inertial navigation system(SINS)/GPS/celestial navigation system(CNS) .With quaternion in strapdown inertial navigation,the combined navigation system by means of federated Kalman filtering method was simulated.The simulation results showed that the system is feasible and effective.
通过分析目前应用较为普遍的几种组合导航方式,针对高超声速巡航飞行器,提出了采用捷联惯性导航系统(SINS)/GPS/天文导航系统(CNS)组合导航作为其中段制导方案,并利用四元数法进行捷联惯性导航计算,运用联邦滤波方法对组合导航进行了仿真,仿真结果表明该方案行之有效。收藏指正
