结合深空通信导航技术的发展趋势,通过分析CCSDS(空间数据系统咨询委员会)的研究领域、应用CCS-DS建议的空间任务,梳理出与深空通信导航相关的CCSDS建议。详细论述了深空任务中射频与调制、带宽频率调制、再生伪码测距以及相对差分单向测距等技术体制的CCSDS建议内容。并重点分析了CCSDS建议对我国深空测控网建设的影响,提出了我国深空测控设备符合CCSDS标准的技术要求。
Combined with the development trend of deep space communication and navigation technology, CCSDS (Spatial Data Systems Advisory Committee) research area is analyzed and the CCSDS recommendations related to deep space communication navigation are combed using the space tasks proposed by CCS-DS. The contents of CCSDS proposed in the technical system such as radio frequency and modulation, bandwidth frequency modulation, regenerative pseudo-code distance measurement and relative differential one-way ranging in deep space mission are discussed in detail. And emphatically analyzes the impact of CCSDS recommendations on the construction of China’s deep space monitoring and control network and puts forward the technical requirements for China’s deep space monitoring and control equipment conforming to the CCSDS standard.
