摘要
近年来IGS基准站的选取是高精度GPS数据处理中讨论的热点问题,但到目前为止,该问题仍然没有得到完全解决。本文从理论和实验两个方面对该问题进行讨论,利用GAMIT/GLOBK软件解算2011年年积日为第274日、275日和276日的数据,分析在解算过程中选取国际GNSS服务组织(International GNSS Service)基准站的空间分布、数量多少、观测时间长短等参数对解算精度的影响。
Recently years, the selection of IGS base stations in high-precision GPS data processing has becoming a hot issue. But so far, this problem has not been fully resolved yet. In this paper, the authors discussed the problem from both the theory and the experiment, calculated the data of annual 274, 275 and 276 in 2011 by use of software GAMIT and GLOBK, and finally analyzed the accuracy affected by the parameters such as spatial distribution, quantity and time of IGS base stations.
