摘要
在轨服务航天器(On-orbit Servicing Spacecraft-OSS)具有重要的军事和民用价值。分析了OSS的导航任务,给出了导航系统总体方案并设计了导航工作模式。构建了OSS导航仿真系统的总体框架,分析了OSS导航仿真系统组成及仿真支撑环境,基于MATLAB/RTW仿真平台开发了OSS导航数字仿真软件。对数据时间同步技术、导航模式切换技术、推力分配算法等关键技术进行了分析。
On-orbit Servicing Spacecraft （OSS） has great military and civil value. This paper focused on the simulation issues of OSS navigation system. Firstly, the navigation misson of OSS were analyzed. The scheme of OSS navigation system and its working modes were designed. Then, the simulation frame of OSS navigation system was presented, its composition and supporting environment were analyzed. Digital simulation software of OSS navigation system based on MATLAB/RTW platform was developed. Some key techniques, such as data synchronization, navigation modes switching, thrust allocation algorithm etc., were analyzed in detail.
