摘　　要：以常用的商业软件TBC及HGO为载体,分别加载精密星历和广播星历进行解算,随机选取解算的57条基线进行分析,并将平差解算结果与已知数据进行对比,分析了平差结果与已知数据差值的原因,结果表明在工程上,C级及以下等级的GPS网在采用商业软件加载广播星历进行解算时,其结果是可靠的.Taking common commercial software TBC and HGO as carriers,load precision and broadcast ephemeris are respectively resolved.Fifty-seven baselines are randomly selected for analysis in this paper,and the adjustment results are compared with the acknowledged data.It shows that for GPS networks of grade C,the results of loading a broadcast ephemeris with the software are reliable.
