Due to the rapid growth of the mass of information, put a higher demand for satellite and ground data transfer rate. When the satellite data rate exceeded 100Mbps, the InterSymbol Interference (ISI) and group delay will have a serious impact on SNR of the satellite link. A new mathematical model of satellite channel was proposed. On the basis of the analysis of high-speed remote sensing satellite link, and combining vector network test results, the authors obtained a new mathematical model of a high-speed satellite link. Through simulation analysis, the amplitude-frequency characteristics and group delay characteristics of the model is corresponded with the actual link. The model laid the foundation for analysis of future high-speed data transfer between satellite and ground.
