1卫星系统典型通信卫星平台包括下列系统。1.1通信和数据处理系统通信和数据处理系统执行3个独立功能:接收和解调从地面站通过指令链路发射给卫星的信息;通过数据链路发送记录(遥控)数据或实时数据至地面接收站;通过遥测链路发送平台设备数据和其他遥测数据至地面站。1.2姿态和轨道控制系统姿态和轨道控制系统用以确定卫星相对于当地法线的精准位置,为通信天线、图像敏感器和其他任务敏感
1 satellite system The typical communication satellite platform includes the following systems. 1.1 Communications and data processing systems Communications and data processing systems perform three independent functions: receiving and demodulating information transmitted from the ground station to the satellite via the command link; sending record (remote) data or real-time data to the ground via the data link Station; sending platform equipment data and other telemetry data to the ground station over the telemetry link. 1.2 Gesture and Orbit Control Systems Attitude and orbit control systems are used to determine the precise position of satellites relative to the local normal, sensitive to communications antennas, image sensors and other tasks
