| 摘 要： | 为研究北斗卫星导航系统单星授时精度，本文基于GPS单星授时原理，结合北斗卫星多种类型星座特点，编写了BDS单星授时软件。利用iGMAS站数据进行了试验，在对原始数据进行监测并将异常信息剔除后，将授时结果与中国测绘科学研究院北斗分析中心（CGS）钟差文件进行比对，分析了BDS不同轨道卫星（GEO/IGSO/MEO）下的BDS单星授时精度。结果表明，GEO卫星的授时精度为27.39 ns，IGSO卫星的授时精度为18.37 ns，MEO卫星的授时精度为18.62 ns。

| Abstract: | In order to study the single-star timing accuracy of the BeiDou Navigation Satellite System, based on the GPS single-star timing principle, combined with the characteristics of the BeiDou satellite multi-type constellation, this paper compiled the BDS single-star timing software. Experiments were carried out using iGMAS station data. After the original data was monitored and the anomaly information was removed, the timing results were compared with the CGS clock difference file of China Academy of Surveying and Mapping, and the BDS different orbit satellites were analyzed. BDS single-star timing accuracy under GEO/IGSO/MEO). The results show that the timing accuracy of the GEO satellite is 27.39 ns, the timing accuracy of the IGSO satellite is 18.37 ns, and the timing accuracy of the MEO satellite is 18.62 ns. |
