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

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. [
