The High Throughput Satellite (HTS) is the major developing and application direction of the new generation wideband communication satellite. The domestic and neighborhood market have a huge demand of HTS. The characteristics and development demands with microwave photonics of HTS were analyzed. The main research developments, especially the new developments of HTS in our country, were introduced. The applications of microwave photonics on HTS and the foreign microwave photonics payloads of HTS were studied. And a new microwave photonics payload scheme was proposed and studied. The effectiveness and feasibility of this microwave photonics payload scheme were tested. In the end, the problems and suggestion of microwave photonics HTS were analyzed.
