这种星载甚高频应答机计划用于同步轨道的轨道试验卫星和航海轨道试验卫星,它作为指令、遥测以及距离和距离变化率测量的备份线铬,能满足欧洲宇航局和戈达德宇航飞行中心标准的要求。该应答机主要由高灵敏度接收讥、中功率发射机,双工嚣以及工作方式选择逻辑电路组成。
This spaceborne VHF transponder is planned for orbital and geostationary orbit satellites for geostationary orbit and serves as backup line chrome for command, telemetry and range and range rate-of-change measurements to meet the needs of European Space Agency and Goddard Aerospace Flight Center standards. The transponder is mainly composed of high-sensitivity receiver, medium power transmitter, duplex driver and working mode selection logic.
