太空交通管理关键技术与发展趋势

The development requirements for space traffic management are combined to systematically sort out the key technologies and development tendencies in this field. First，the background of the emergence of space traffic management is expounded，and its core connotation is clarified. The major issues faced by space traffic management are analyzed from three dimensions：target situation awareness，threat warning，and management response. The development status of key technologies in each dimension is comprehensively sorted out，and the application characteristics and limitations of different technologies are summarized. In view of the future space traffic scenarios with large-scale space targets and multiple types of space activities，six development tendencies of space traffic management are proposed，including intelligent identification technology for high-risk space traffic targets，design technology for space traffic monitoring and management constellations，rapid orbit prediction technology for large-scale space targets，space traffic situation assessment and risk early warning technology，space traffic injection/deorbit corridor planning and flow regulation technology，and space traffic space-ground integrated command and management technology. The research results provide important references for the construction of China’s space traffic management system and the development of technical capabilities，and lay a theoretical and technical foundation for coping with the complex space traffic environment and ensuring the safe and orderly development of space activities.
