摘要
随着高精度GNSS在地学中的应用越来越广泛,如何提高GNSS数据处理精度成为一个热点问题。IGS站的选取对GNSS数据处理的精度起着重要的作用。论文以GNSS数据处理软件GAMIT进行数据处理为例,从IGS站选取的几何意义和统计意义,研究其对GNSS数据处理精度的影响。通过比较和分析,说明合理先取IGS站点能够有效提高基线解算的精度,并对合理选取IGS站点的方法提出建议。
With the increasing application of high-precision GNSS in geoscience,how to improve the precision of GNSS data processing has become a hot issue.The selection of IGS stations affects the accuracy of GNSS data processing a lot.This paper uses the software GAMIT for GNSS data processing.The influence of geometric and statistical meanings of IGS station selection on the accuracy of GNSS data processing are studied.Through comparison and analysis,it is shown that the reasonable selection of IGS stations can improve the accuracy of the baseline calculation.Suggestions on selecting IGS sites are put forward.
