Research on the Development Strategy of Real-Time and Intelligent Space-Based Information Service System in China

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 收稿日期:2019-09-19;修回日期:2020-01-15 通讯作者:李德仁,武汉大学教授,中国工程院院士,中国科学院院士,研究方向为地球空间信息学;E-mail: drli@whu.edu.cn 资助项目:中国工程院咨询项目“天基信息实时服务系统(PNTRC)发展战略研究”(2017-ZD-01) 本刊网址:www.engineering.org.cn/ch/journal/sscae DOI 10.15302/J-SSCAE-2020.02.017
