【摘要】 文中研究了基于多传感器信息融合技术的SINS/基于地日月信息的定位系统(ESMPS)/星跟踪器(ST)组合导航系统,以实现航天器高精度自主导航定位。文中设计了自适应联邦滤波器,通过引入基于地日月信息的定位系统和星跟踪器信息,对捷联惯导系统进行实时估计与校正,抑制其误差累积。仿真结果证明,该系统具有较高的精度、自主性和鲁棒性。更多还原

【Abstract】 In order to carry out high precision auto-navigation for aero craft the SINS/ESMPS/ST integrated navigation based on information fusion is developed. The paper designs a self-adaptive federated filter and introduces the ESM position system and the star tracker that can modify the SINS system. The simulation result can show the high-precision, autonomy, and robusticity of the system.更多还原
