| 摘 要： | 当利用GPS测站坐标残差数据分析研究测站坐标周年非线性变化规律时,GPS技术本身的周年系统性误差是其中重要部分。本文针对GPS技术的周年变化特点利用并置站SLR残差数据对GPS测站残差数据中的部分周年系统性误差进行了检测分析,对于进一步量化GPS周年系统性误差对测站坐标精度以及测站坐标周年非线性变化的影响有一定的借鉴意义。

| Abstract: | When studying the site coordinates seasonal non-linear movement with GPS residuals,it was found find that the GPS seasonal systemical error is an important part.Considering the technical characteristics of GPS,the paper used SLR residuals in the same station to detect GPS seasonal systemical error.There would be a certain significance to estimate the impact of GPS seasonal systemical errors on sites coordinate annul non-linear movement. |
