【摘要】 星座全寿命飞行任务规划包括构型设计、部署任务规划、发射窗口计算、站位保持控制、星座重构设计、补星发射分析、卫星离轨机动等内容,存在功能复杂、仿真周期长、计算量大的特点,必须借助计算机仿真系统进行分析计算。针对星座飞行任务的内容,开发了适用于星座全寿命飞行任务规划的仿真系统CDT(Constellation Design Tool)。仿真系统采用客户/服务器的运行方式,具有友好的操作界面,用户通过客户端进行操作,服务器承担计算和存储计算数据的任务。介绍了仿真系统的功能要求,给出了系统设计方案、软件结构、运行流程、数据库设计方法等。最后用该仿真系统对一个导航星座进行了全寿命飞行任务的规划。更多还原

【Abstract】 The lifecycle flight mission plan of satellite constellation comprises constellation configuration design,deployment strategy,launch window calculation,station keeping control,reconfiguration design,satellite replenishment and satellite de-orbiting maneuver. There were some characteristics such as complicated function,long period simulation,large amount calculation about the flight mission plan,and it could only be solved by computer simulation system. A simulation system called CDT(Constellation Design Tool) was developed,which could be used for lifecycle flight mission plan of constellation. The simulation system was based on client/server run mode,the interface on the client was visual and convenient to use,and the server had its shoulders on the calculation and data storage. The function of the simulation system was introduced,and the system’s design scheme,software structure,flow chart,database design method were proposed. Finally,the simulation system was used to complete the lifecycle flight mission plan of a navigation constellation.更多还原
