精密星历与广播星历下C级GPS网解算精度分析
|
摘要
分别在精密星历与广播星历下采用TBC 2.8数据处理软件进行C级全球定位系统(GPS)控制网基线解算,并采用GAMIT加载精密星历文件进行基线解算,在COSAGPS软件中进行环闭合差统计及平差计算.针对上述方法得出的数据进行比较,分析TBC软件采用不同星历解算对C级GPS基线解算及网平差成果的影响,研究发现TBC在两种星历下均可进行C级GPS数据解算,但在精密星历下的基线解算精度较高,在工作中可根据实际情况采取恰当的方法作业.
This paper uses Trimble Business Center 2.8 data processing software to perform C-Grade GPS control network baseline solution and network adjustment with precision ephemeris and broadcast ephemeris. The GAMIT software is used to load precise ephemeris data for baseline solution, and the adjustment calculation is performed with the COSAGPS software. According to the data obtained with above methods, the influence of different ephemeris solutions on the C-Grade GPS baseline solution and the network adjustment results are analyzed. The results yield that the TBC software can respectively perform C-Grade GPS analysis with both ephemeris, but the accuracy of the baseline solution with the precise ephemeris is slightly high. Thus the appropriate data process strategy should be employed according to the actual situation in fieldwork.
