卫星分系统仿真测试平台设计与实现

Design and Implementation of Simulation Test Platform for Satellite Subsystems

卫星三级测试包括设备级测试、分系统级测试和整星级测试,测试成本较为昂贵,为了达到尽早的开展分系统级测试的目的,提出了一种数字仿真环境同单机设备相结合的分系统仿真测试平台的设计方法;通过对各单机设备进行仿真建模,并依据设备间的数据交互方式进行物理实现,为单机设备构建分系统级的测试环境;解决了在缺少单机设备时无法开展分系统级测试的难题;尽早的对单机设备进行分系统级测试,可以在早期就发现单机设备存在的缺陷并进行改正,从而达到节省测试成本的目的。

Satellite three levels test including equipment test. subsystems test and satellite level test. Testing costs are very expensive. In order to achieve the purpose of earry out subsystem test as soon as possible, we proposed a design method of the subsystem simulation test platform which using digital simulation environment combined with the physical environment; Through simulation modeling of equipment and implements communications for equipment to build subsystem level testing environment; The simulation test platform has solved the problem that before all equipment is completed carry out subsystem level testing; Start subsystem level test before all of the satellite equipment has so that, we can achieve the purpose of saving development
