With the rapid development of earth observation technology, remote sensing satellite resources are becoming more and more abundant. In order to full play to the effectiveness of the ground receiving system, it is necessary to meet the multi-function of one station. The antenna can receive data from both low-orbit remote sensing satellites and high-orbit remote sensing satellites, and meet the receive needs of multiple bands. Channel configuration needs to meet the satellite data receiving requirements of different frequency bands, different demodulation modes and different coding and decoding. The satellite-to-ground link analysis and calculation are carried out for different modes of satellite, On this basis, the system composition and working principle are introduced, and the data receiving process of satellite is designed. At the same time, the key points of the system, single-high code rate demodulation decoder and optical transmission are analyzed in detail. Finally, the design has been verified by practical engineering application, which meets the application requirements of the project
