摘要
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。
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.
