The diversity of space missions presents enormous challenges to the development of satellite ground TT&C station. The modular construction of equipment can bring about many improvements to space equipment construction. First, this paper analyzes the demands of space missions to find out the key points and connotations of satellite ground TT&C station. Second, the basic development elements of modular connotations, the capacity requirements of satellite ground TT&C station and the current status of equipment construction are analyzed, and the modular construction of satellite ground TT&C station is proposed. Finally, combined with the positive role of modular construction and development, suggestions for the modular construction of satellite ground TT&C station are presented, which can effectively support the modular construction and development of satellite ground TT&C station.
