法国图卢兹空间飞行器方案组于1978年9月确定的SPOT星载通信和数据管理(C&DH)系统具备遥测、遥控、跟踪、服务舱和有效载荷数据管理等主要功能。 C&DH系统涵通信和数据管理两部分。通信部分由天线、双工器和转换开关、发射机、接收机以及电源和远程终端单元(RTV)等部件组成。数据管理部分由译码器、计算机、存储器、卫星控制器(SCC)、数据总线以及电源和RTU单元等部件组成。在SPOT卫星捕获、重新捕获、例行
The SPOT satellite communications and data management (C & DH) system, identified by the French Toulouse space program team in September 1978, has the main functions of telemetry, remote control, tracking, service class and payload data management. C & DH system Han communications and data management in two parts. The communications section consists of antennas, duplexers and transfer switches, transmitters, receivers, and power and remote termination units (RTVs). Data management part consists of decoder, computer, memory, satellite controller (SCC), data bus and power supply and RTU unit and other components. In the SPOT satellite capture, recapture, routine
