Constellation Design and Application of Real-Time Space-Based Information Services Supporting Communication, Navigation and Remote Integration

The existing communication, remote sensing and navigation satellite systems are self-contained resulting in system isolation, information separation, service lag, poor information sharing and interaction. Moreover, the applications of space-based information in communication, remote sensing and navigation are mostly independent of each other. By integrating the communication, navigation, remote sensing and other loads with the platform, we can provide the task-oriented space–time services and construct an all in all system with multi-purpose, multi-satellite networking, multi-network integration and intelligent services. In this paper, we propose a constellation design method, which can support the real-time service of space-based information by integrating the communication, guidance and remote. The model of satellite scale prediction is established based on the optimization algorithm of coverage band. Considering all kinds of load performance, phase relationship, inter-satellite link construction and other constraints, the number of satellites, constellation configuration and deployment scheme are determined.
