ITRF2014: A new release of the International Terrestrial Reference Frame modeling nonlinear station motions

Journal of Geophysical Research: Solid Earth, 2016
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 seasonal (annual and semiannual) signals of station positions and postseismic ...

ITRF2008: an improved solution of the international terrestrial reference frame

Journal of Geodesy, 2011
ITRF2008 is a refined version of the International Terrestrial Reference Frame based on reprocessed solutions of the four space geodetic techniques: VLBI, SLR, GPS and DORIS, spanning 29, 26, 12.5 and 16 years of observations, respectively.

A Global Combination of Geodetic Techniques at the Observation Level: New Perspectives on the Terrestrial Reference Frame

Journal of Geophysical Research: Solid Earth
We describe the development and assessment of a new terrestrial reference frame (TRF) based on a combination of geodetic techniques at the observation level over the period 2010–2022.

On the relation of GNSS phase center offsets and the terrestrial reference frame scale: a semi-analytical analysis

Journal of Geodesy, 2022
Phase center offsets (PCOs) of global navigation satellites systems (GNSS) transmit antennas along the boresight axis introduce line-of-sight-dependent range changes in the modeling of GNSS observations that are strongly correlated with the estimated ...

Consistent realization of Celestial and Terrestrial Reference Frames [PDF]

Journal of Geodesy, 2018
The Celestial Reference System (CRS) is currently realized only by Very Long Baseline Interferometry (VLBI) because it is the space geodetic technique that enables observations in that frame. In contrast, the Terrestrial Reference System (TRS) is realized by means of the combination of four space geodetic techniques: Global Navigation Satellite System (

Optimizing realization of the terrestrial reference frame on a regional basis: A case study using the crustal movement observation network of China

, 2021
It is critical in the study of crustal deformation to reduce TRF-related system errors and enhance the accuracy of GPS coordinate time series. To reduce system errors associated with the coordinate time series, which are related to the terrestrial ...
