Abstract
As a core support system, China's deep space TT&C (tracking telemetry and command) network plays an irreplaceable role in deep space exploration. Driven by China's Lunar Exploration Project, the deep space TT&C network, with complete functions, advanced performance, and global layout, has been built in stages. Additionally, driven by the future lunar and planetary exploration projects, China's deep space TT&C network will realize stronger deep space tracking and telecommunications capabilities through the application of new technologies such as antenna arraying, optical communication, and phase reference interferometry. It will also be useful for deep space scientific exploration activities.
