摘要
以组建具有良好可扩展性和可重用性的仿真系统为目的,在HLA分布式仿真技术的基础上,采用面向对象的建模与仿真技术分析并设计了分布式的航天任务仿真系统。系统由控制中心,测控站,航天器和视景显示四类联邦成员组成,控制中心和测控站构成虚拟的航天测控网,完成对航天器的监测和控制,仿真结果通过视景联邦成员用3D图像表现出来。在对仿真系统不作任何修改的情况下,加入不同个数的航天器联邦成员,能够完成诸如单个航天器入轨和卫星星座等的航天任务仿真。在此仿真系统的基础上,通过扩展和重用,可以方便的组建特定目的的其它航天任务仿真系统。面向对象的建模与仿真技术应用于空间总体技术仿真是一种新方法,有利于更大规模的系统集成,也便于仿真组件的发展与重用。
Aiming at building simulation system with great extensibility and reusability, a distributed space mission simulation system was designed based on HLA (High Level Architecture). The system was composed of control center, ground station, spacecraft and scene driver four types federate, control center and ground station constitute a virtual telemetry, tracking and control (TT&C) network, this network tracks and controls spacecraft flying; simulation result drives the scene driver and print 3D scene to output device. Other space mission simulations such as constellation simulation etc can be performed as well as single spacecraft simulation with the system. Based on the space mission simulation system, some other space mission simulation system can be achieved easily for different simulation purpose by modifying and reusing existed components. Object-oriented modeling and simulation technology is a new method to space technology simulation, it facilitates building large scaled simulation system and benefits simulation components reuse and future extension.
