According to the large link margin for high-speed data transmission on remote sensing satellite, an efficient transmission method based on adaptive coding and modulation (ACM) technology for remoting sensing satellite is developed in this paper, which makes the best use of free-space loss and rain attenuation margin to achieve the most dada transmission, for the satellite adjusting the modulation coding scheme(MCS) during the transmission. This method can effectively resolve the bottle-neck about hardware and frequency resource on high-speed data transmission of remote sensing satellite, which can be applied to satellite-satellite and satellite-earth station data transmission for almost all satellites. Finally, the efficiency of ACM for LEO and HEO remote sensing satellite is analyzed, and result proves that ACM is three times as large as CCM about dada transmission.
