Abstract: Aerospace TT & C communication system is the key of aerospace TT & C system. This paper focuses on the communication and data transmission system, and studies how the spacecraft measurement and control system improves the anti-jamming ability in the complex electromagnetic environment of the launch site. Firstly, this paper discusses the current situation and development trend of aerospace measurement and control communication system, then analyzes the anti-interference ability of current aerospace communication system, and then introduces the electromagnetic interference sources of aerospace TT & C system and three development stages to improve electromagnetic compatibility. Then, the anti-jamming technology and the application of electromagnetic compatibility of aerospace TT & C system are introduced. Finally, aiming at the improvement of electromagnetic compatibility between aerospace TT & C systems, the improvement of internal electromagnetic compatibility of aerospace TT & C, the anti-interference ability improvement scheme of spacecraft TT & C system is proposed from three aspects of restraining environmental electromagnetic interference.
