On Civil-Military Integrated Space-Based Real-Time Information Service System

We introduce the background of civil-military integration strategy, analyze the achievements and challenges of the present situation of China's space-based information system, and discuss the strategic significance of the construction of a civil military integrated space-based real-time information service system. A proposal for the construction of communication-navigation-remote sensing integrated space-based information service system (including positioning, navigation, timing, remote sensing, and communication functions, PNTRC) is put forward. The ultimate goal is a implementation strategy, technical roadmap, and prospective PNTRC application. Key technologies for the construction of PNTRC are analyzed, some suggestions for key technologies are presented.
