    摘要:

    随着深空探测距离的延伸,对于航天器的测量显得尤为重要。其中,航天器相对于测量站之间距离的测量是深空探测中的重要一环。基于再生伪码测距的特点进行分析,介绍了伪码测距的发展历程,分析了再生伪码测距的优势,对再生伪码测距中采用的测距码的发展历程、码型选择进行了论述,对Tausworthe两种码在测距精度以及捕获时间上进行了分析,之后对码速率获取以及码捕获等方面进行了相关讨论,最后,对再生伪码测距中存在的问题进行了表述,点明了接下来的研究工作。

    Abstract:

    With the extension of the deep space detection, the measurement of spacecraft is particularly important. The measurement of the distance between the spacecraft and the measuring station is an important part of the deep space detection. This paper is based on the characteristics of regenerative pseudo code ranging, and the paper introduces the development history of pseudocode ranging, analyzes the advantages of regenerative pseudocode ranging, discusses the development process and pattern selection of the distance code used in regenerative pseudocode ranging, and Tausworthe for two yards in the ranging accuracy and capture time were analyzed, then the speed rate acquisition and the code acquisition are also discussed. Finally, the existing problems in the reconstructed pseudocode ranging are described, and the next research work is pointed out.
