| 摘 要： | 在某型卫星地面电联试过程中,对该卫星的姿态轨道控制系统进行接口分析及信号统计,针对其接口复杂性、信号多样性的特点,提出采用片上系统(Systemona Chip,SOC)芯片对所有部件模拟器进行通用化设计。文中给出了该型卫星通用型电模拟器硬件平台设计方案以及陀螺、反作用轮和通用接口模块的硬件配置说明,针对该型卫星姿态轨道控制系统电联试要求,对所有部件按真实接口配置成电模拟器,形成通用接口箱、敏感器电模拟器箱和执行机构电模拟器箱,并通过CAN(Controller Area Network)总线接入闭环仿真,对太阳捕获、地球捕获及正常模式进行了仿真测试,仿真结果表明通用电模拟器满足设计要求,对其他卫星的地面电联试有很好的参考价值。
