卫星编队自主相对导航与通信一体化系统探讨

Discussion on Autonomous Relative Navigation and Communication Integrated System for Satellite Formation

探讨了一种新的卫星编队自主相对导航与通信系统一体化系统设计方案,提出了基于软件无线电的半双工CDMA测量通信一体化系统,实现自主相对导航和星间通信的一体化功能,通信数据和导航测量数据也统一在一个数据帧中传输,不需要独立的星间网络通信系统和增加额外的通信频段进行通信数据传输。系统采用S波段,详细阐述了系统架构和工作原理,分析了系统性能,并进行了仿真验证。

In this paper,a new design for relative navigation and communication system integration system was discussed,and a relative measurement and communication integration system of half duplex CDMA based software radio was proposed to realize the integration of relative achieve navigation and inter-satellite communication,and the communication data and navigation measurement data were transmitted in one data frame,sothe new system did not require a separate inter-satellite communication and extra frequency.The system architecture and working principles were described in detail.The system performance was analyzed,and the simulation was done.
