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。
A new integrated system design of autonomous relative navigation and communication system for satellite formation is discussed. An integrated system of half-duplex CDMA measurement and communication based on software radio is proposed to realize the integrated function of autonomous relative navigation and inter-satellite communication. The communication Data and navigation measurement data are also unified in a data frame transmission, does not require a separate inter-satellite network communication systems and additional communication bands for communication data transmission. The system adopts S band, elaborates the system architecture and working principle in detail, analyzes the system performance, and carries on the simulation verification.
