摘　　要：为了对BDS卫星系统在全球IGS站点中的推广和建设情况有进一步的了解,研究全球IGS站点对BDS信号的接收情况,分析2020年DOY165中302个IGS跟踪站的BDS接收情况和信号频点兼容情况。结果表明,BDS信号在东、西半球的利用率有较大区别,B3频点在全球的普及不如B1、B2两个频点;3个频点的多路径误差和信噪比具有不同的特点。In order to have a better understanding of the promotion and construction of BDS in global IGS stations,this paper first introduces the development plan and recent situation of BDS.The reception of BDS signals by global IGS sites is studied.Then the BDS reception status and signal frequency band compatibility status of 301 IGS tracking stations in DOY165 in 2020 is analyzed.Finally,this paper studies the quality of the data that can receive BDS signal stations the data integrity rate,multi-path error and signal-to-noise ratio.The results show that the ratio of BDS signals received by IGS tracking stations in the eastern and western hemispheres is quite different.The global popularity of the B3 frequency band is not as good as that of the B1 and B2 frequency bands;the multipath error and signal-to-noise ratio of the three frequency bands have different characteristics.
