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.
