Abstract: In this paper, the author gives a comprehensive review of the achievements made by China in the construction of deep space TT&C system, combining with the development of the TT&C system from near earth to deep space during the 17 years since the successful implementation of the three-step strategy of “circling, landing and returning” of China’s lunar exploration project. From the breakthrough of long-distance TT&C technology in the first phase of the lunar exploration project, to the initial completion of the deep space TT&C network of two domestic deep space stations in the second phase of the lunar exploration project, to the completion of the Deep space station in Argentina in the third phase of the lunar exploration project, a complete deep space TT&C capability was formed. Today, China’s deep space TT&C system has become one of the three global deep space TT&C networks in the world, and is capable of independently supporting lunar and deep space exploration missions. In the future, China’s deep space TT&C system will continue to develop and grow in accordance with the principle of unified planning and step-by-step construction, which will further enhance China’s support capacity for deep space TT&C.
