中国第一代导航卫星系统北斗一号无线电波的频谱特征

北斗一号是中国第一代区域性卫星导航和定位系统。本文综合国外对该系统的无线电波的频谱特征作一综合介绍。论述了北斗一号导航和定位系统的构成、工作频率和地面待定点的定位精度,论述了该系统的工作程序和北斗卫星的频谱,以及北斗卫星信号的特征图。

The spectrum characteristics of the radio frequency of chinese first generation satellite navigation system-beidou I

Beidou I is Chinese satellite navigation and positioning system of first generation. It covers territory and its surrounding area. The spectrum characteristics of the radio signal of “Beidou I” surveyed by foreign country are introduced in the paper. The construction and working frequency of "Beidou Ⅰ" satellite navigation and position system as well as position precision of ground point to be located are discussed. At the same time, it gives the discussion of the system’s working program, the frequency spectrum of "Beidou" satellite as well as the feature map of “Beidou” satellite’s signal.
