Abstract
Real-time and intelligent space-based information service system is a next-generation space-based system that integrates satellite communications, satellite navigation, and satellite remote sensing. It delivers space-based information to civil and military users as required in real time, relying on multi-load integration, multi-satellite collaboration, and interconnection between space and ground networks. This paper first analyzes the strategic requirements for real-time and intelligent space-based information services, then reviews the development status of satellite communications, satellite navigation, and satellite remote sensing in China and abroad, and summarizes the existing problems. Moreover, it expounds the basic concept, objectives, and technical architecture of the real-time and intelligent space-based information service system, and analyzes the relationship between this system and the existing (or planned) space-based information system, thus demonstrating its feasibility for construction. The real-time intelligent space-based information service system can be established through three steps and developed first locally, then regionally, and finally globally. This system should be incorporated into the overall planning for national science and technology development, and be constructed and shared mutually by civil and military parties. During the construction of this system, communicating and integration with existing and planned communications, navigation, and remote sensing satellites as well as with the ground communication systems should be strengthened.
