GPS数据高精度基线解算方法分析

Methods for High Accuracy Baseline Processing of GPS Data

针对GPS数据高精度基线解算方法的研究,结合GAMIT软件应用中的一些常见问题,通过大量试验数据系统分析了对流层折射模型改正、卫星截止高度角、观测量采样率和观测时间长度对于基线解算结果的影响,提出了在不同情况下高精度基线解算的准则。

From the study to due with the ways of high accuracy baseline processing, this paper analyzed the common errors in using GAMIT for baseline processing, and based on the analysis of the influence to baseline processing result, including troposphere refraction model influences, satellite cut-off elevation angle, observation sampling and measuring time from mass of testing data, the rules of high accuracy baseline processing in different conditions were studied.
