| 摘 要： | 当前关于IGS站选择对GPS数据解算的影响尚未有定论,讨论陆态网数据解算过程中IGS站的选取问题,简要介绍陆态网和GAMIT软件,分析IGS基准站的分布以及数量对陆态网解算精度的影响。在本文的GAMIT参数设置下,通过实验发现,进行陆态网解算时只需要加入北半球的IGS站就可使基线得到较好的U方向解算精度,而陆态网选择8个左右的IGS站较为合适。

| Abstract: | Recently years, the problem of the selection of IGS base stations in high-precision GPS data has not been fully resolved.This paper mainly discusses the selection of IGS station in data processing of CMONOC, briefly introducing the CMONOC and GAMIT software, and analyzing the influence of the distribution and the number of IGS reference stations on the data processing of CMONOC.Through the experiment in the setting of GAMIT parameters in this paper, the numerical calculation shows that the IGS stations located in Northern Hemisphere are added up to obtain better accuracy in the U-direction of baselines.Eight IGS stations are proper for the CMONOC. |
