摘　　要：随着北斗系统全面建成,北斗短报文在我国卫星测控领域的应用逐渐展开。为了充分利用北斗短报文双向通信功能、保密性好、全球覆盖等特性,参考国际空间数据系统咨询委员会(Consultative Committee for Space Data Systems,CCSDS)的可扩展标记语言的遥测遥控信息交换(XTCE)标准,提出了融合北斗短报文与CCSDS标准的卫星遥测遥控数据系统设计方法。首先,分析了CCSSDS XTCE和北斗短报文的应用现状;其次,考虑到北斗短报文的容量限制,设计优化了卫星遥测遥控数据传输格式和内容;再次,针对北斗短报文传输特性,探讨了加密通信方法;最后,为保证遥测遥控数据传输的正确性与可靠性,设计了数据连续识别和丢包补发方法。结果表明,融合北斗短报文与CCSDS标准的卫星遥测遥控数据系统,可以为提高卫星的设计与科学使用提供参考。With the completion of the Beidou system,the application of Beidou short message in the satellite measurement and control field in China is gradually expanding.In order to make full use of Beidou short message bidirectional communication function,good confidentiality,global coverage and other features,a satellites'design method telemetry and telecommand data system based on Beidou short message and CCSDS standard is proposed by referring to XTCE standard of extensible markup language.Firstly,the application status of CCSSDS XTCE and Beidou short message is analyzed.Secondly,considering the capacity limitation of Beidou short message,the format and content of satellites'telemetry and telecommand data transmission are optimized.Then,according to the characteristics of Beidou short message transmission,the encryption communication method is discussed.Finally,in order to ensure the correctness and reliability of telemetry and telecommand data transmission,the methods of continuous data identification and packet loss and retransmission are designed.The results show that the satellites'telemetry and telecommand data system design method combining Beidou short message and CCSDS standard can provide reference for improving satellite design and scientific use.
