China´s spaceflight missions are more and more complex and diversified and their requirements on TT&C systems are taking on more and more high level, precision and sophisticated features. As such, China´s spaceflight TT&C systems are again facing new opportunities and challenges. Based on a comprehensive analysis of the road of development and status quo of spaceflight TT&C systems at home and abroad, this paper summarizes the features and trend of development of spaceflight TT&C systems, and proposes an integrated ground, air and space development strategy for TT&C and communication system including optimization of the ground-based TT&C network, development of a space-based TT&C network and development of a deep space network taking into consideration the specific conditions of China in the field. The paper also explores key technologies for development of China´s ground-based, space-based and deep space exploration TT&C and communication networks.
