Introduction to System Design of Ground Receiving System of a Remote Sensing Satellite

遥感卫星地面接收系统包括天伺馈系统、跟踪接收信道分系统、数据记录处理和快视分系统、遥测遥控分系统、任务管理分系统、测试标校分系统。在对接收系统进行方案设计时 ,应针对不同遥感卫星的轨道、数据速率、成像方式等 ,重点解决多星适应性、卫星过顶跟踪、双通道实时合成及快速反应等关键技术 ,并对系统主要指标进行计算。介绍了遥感卫星地面接收系统总体设计的方案、关键技术及解决途径。

The ground receiving system of the remote sensing satellite consists of the antenna, transmission and servo sub systems, the tracking and receiving sub system, the data recording, processing and fast look sub system, the telemetering and remote control sub system, the mission management sub system, the test and calibration sub system etc. In the conceptual design of the receiving system, for different orbit, data rate and imaging pattern of different remote sensing satellite, some key technologies such as the multi satellite adaption, the satellite overhead tracking, double channel real time synthesizing and fast response technique should be implemented. And the main specifications of the system should be figured out. A system design of the ground receiving system for the remote sensing satellite is presented in this paper. Key techniques, and calculation of main parameters of the system are also discussed. [
