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 …

For the first time in the International Terrestrial Reference Frame (ITRF) history, the
ITRF2014 is generated with an enhanced modeling of nonlinear station motions, including …

Automatic estimation of velocities from GPS coordinate time series is becoming required to
cope with the exponentially increasing flood of available data, but problems detectable to …

The Global Positioning System (GPS) is a navigation system based on satellite technology.
Its fundamental technique involves measuring the ranges between the receiver and a few …

A total of 954 continuous GPS position time series from 414 individual sites in nine different
GPS solutions were analyzed for noise content using maximum likelihood estimation (MLE) …

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 …

Abstract The Global Positioning System (GPS) is an important tool to observe and model
geodynamic processes such as plate tectonics and post-glacial rebound. In the last three …

The accuracy of Global Positioning System (GPS) time series is degraded by the presence
of offsets. To assess the effectiveness of methods that detect and remove these offsets, we …

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 …
