GPS网平移法反演地心运动研究

Research about Geocenter Motion from GPS Translational Approaches

本文将CF、CE相对于CM的运动统称为地心运动。利用网平移法对全球分布站的32年的数据,分别进行了CF相对CM、CE相对CM、CE相对CF运动的反演,得到较长的地心运动的时间序列。并与已有地心运动的研究结果进行比较,得出振幅在同一数量级、且相对较小的结果。

The movements of CF , CE relative to CM will be collectively defined as the geocenter motion in this paper.By using the translational approaches the longer geocenter motion time series are got from the data of 32years global distributed stations , separately about CF relative to CM , CE relative to CM , and CE relative to CF movement.And the results of this paper are compared with previous research achievements.It turns out that the results are much smaller and of the same order of magnitude as the previous research results.The movements of CF relative to CM and CE relative to CM are in millimeter level , as well as CE relative to CF is in submillimeter level.
