The application of TDRSS in TT&C of launch vehicle can improve the coverage and transmission rate of TT&C link. But the transmission protocol based on fixed transmission rate can not ensure the stable TT&C link based on TDRSS. The adaptive transmission protocol proposed in this paper can adjust the transmission rate according to the real-time transmission status during the whole flight. According to the different types of rocket-borne subscriber terminals, the open loop adaptive transmission protocol and closed loop adaptive transmission protocol are designed, which can both keep the stable transmission and improve the transmission efficiency.
