“…The implementation of China's deep space telemetry, track and command (TT＆amp;C) system has always revolved around the three-step strategy of the lunar exploration project, including “circling”, “falling” and “returning”, which helps us to make great achievements from the breakthrough of key technologies, the initial construction of the system to the optimization of the system.At present, the success of Mars exploration will further promote our ability of deep space TT＆amp;C system construction.In terms of the view of the key technologies of deep space response and the ground station system construction, the development process of China's deep space TT＆amp;C system from scratch was reviewed, and the key technologies of Mars deep space TT＆amp;C system were summarized.At the same time, in view of the advantages of the United States in planetary exploration, the deep space response technology of the “
Perseverance” rover was analyzed and summarized, which can provide reference for the future development of Mars exploration in China.Furthermore, considering the construction of the US deep space station and the current rapidly growing demand for future deep space exploration missions, the system structure, overall performance, key system design issues and contributions of these Chinese deep space stations were briefly reviewed.…”
