摘　　要：在GPS基线解算中,卫星星历是解算基线的数学基础,星历的精度对基线解算结果具有影响。卫星星历有两种,广播星历和精密星历.本文应用BERNESE数据处理软件对不同长度的基线进行解算,用实例讨论了两种星历对基线解算结果与精度的影响,得出了一些有益的结论和建议。In GPS baselinge computing, the satellite ephemeris is the math base of computing baseline. The ephemeris precision carries weight on the baseline computing result. The ephemeris has two forms, broadcast ephemeris and exact ones. This paper, based on BERNESE data processing software, deals with different length baselinge to compare the eddocts of the two forms on the computing baseline result and precision through examples, and gives some useful conclusions and suggestions.
