Vertical land motions are a key element in understanding how sea levels have changed
over the past century and how future sea levels may impact coastal areas. Ideally, to be …

Geodesy, the oldest science, has become an important discipline in the geosciences, in
large part by enhancing Global Positioning System (GPS) capabilities over the last 35 years …

长期累积的全球卫星导航系统(GlobalNavigationSatelliteSystem, GNSS)
基准站坐标时间序列为大地测量学及地球动力学研究提供了基础数据. 通过完善GNSS …

利用香港GPS 连续运行参考站网络2001 年1 月至2007 年8 月的观测资料,
全面深入地分析了12 个基准站坐标序列特征. 本文采用主成分空间滤波算法去除公共误差 …

Abstract The Global Positioning System (GPS) measures elastic ground loading deformation
in response to hydrological mass variations on or near Earth's surface. We present a time …

This study focuses on the effects of time correlation in weekly GPS position time series on
velocity estimates. Time series 2.5 to 13 years long from a homogeneously reprocessed …

We compare approximately 3 years of GPS height residuals (with respect to the International
Terrestrial Reference Frame) with predictions of vertical surface displacements derived from …

We propose a methodology to assess the noise characteristics in time series of position
estimates for permanent Global Positioning System (GPS) stations. Least squares variance …

Time series of position changes estimated from data from 236 continuously recording GPS
receivers operating in Southern California and Southern Nevada are evaluated for noise …

Hydrological processes cause variations in gravitational potential and surface deformations,
both of which are detectable using space geodetic techniques. We computed elastic …
