Abstract: In recent years, the development of information technology has advanced by leaps and bounds. The application of information technology is further affecting the direction of human society development, leading, supporting and serving the development and changes of society. Information and communication networks are also moving from fixed networks to mobile networks, from terrestrial, surface, and spatially isolated networks to the heaven and earth fusion network. The heaven and earth fusion network extends human activities to a major information infrastructure in space, the distant sea and even deep space. It realizes the deep integration of space-based network and ground-based network, based on information transmission and exchange, processing and application as the core, and supports future space exploration and development.The heaven and earth fusion network adapts to the needs of economic and social development mode transformation and information technology development, and is the focus, focus and direction of information technology, information industry，information network and information development. In this context, this paper first analyzes the development history of the satellite standard for the integration of the heavens and the earth, studies the system architecture of the heaven and earth fusion standards in each major standard organization system, and then analyzes the existing standard achievements and their main research contents. Finally, the subsequent development direction and research content of satellite communication standards in the heaven and earth fusion network are discussed, and corresponding development suggestions are given.

Key words: the heaven and earth fusion network, satellite communication, standard study, analysis and planning
