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。
Constellation life-span mission planning includes configuration design, deployment mission planning, launch window calculation, station hold control, constellation reconstruction design, satellite launch analysis, satellite derailment and other activities, there are complex functions, long simulation cycle, calculation Large amount of characteristics, we must use computer simulation system for analysis and calculation. According to the content of constellation mission, Constellation Design Tool (CDT) is developed for simulation system of constellation life-cycle mission planning. The simulation system adopts the client / server operation mode, has a friendly operation interface, the user operates through the client, and the server takes the task of calculating and storing the calculation data. The functional requirements of the simulation system are introduced, and the system design scheme, software structure, operation flow and database design method are given. Finally, the simulation system is used to plan the life-cycle mission of a navigation constellation.
