CCSDS建议的再生伪码测距性能分析

Performances Analysis of Regenerative Pseudo-Noise Ranging Recommended by CCSDS

CCSDS(国际空间数据系统咨询委员会)于2009年3月发布了伪码测距的蓝皮书,规定了再生伪码测距的技术要求。我国正在研制的深空应答机和深空站测控设备要求具备再生伪码测距功能,同时为了实现国际联网,伪码测距系统需满足CCSDS建议的要求。为给我国深空测控设备伪码测距系统的研制提供设计依据,通过分析伪码特性和伪码捕获跟踪方法,推导得到伪码测距的捕获性能和跟踪性能。分析得到的性能与CCSDS建议书一致,可作为我国深空应答机和深空站测控设备伪码测距系统设计的参考。

CCSDS（Consultative Committee for Space Data System） published the blue book for pseudo-noise（PN） ranging systems on March 2009,which will be the standards of PN ranging for international cooperation.The deep space transponders and equipments of deep space stations in China will have the functions of regenerative PN ranging to satisfy the requirements for CCSDS recommendations.The acquisition and ranging jitter performances of the regenerative PN ranging are derived by analyzing the properties of PN codes and acquisition and tracking methods of the codes.The results are in accord with the recommendations of CCSDS and will be important references for designing the regenerative PN ranging systems of the deep space transponders and equipments of the deep space stations.
