Atmospheric Excitation of Length of Day Inferred From 21st Century Climate Projections

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract On seasonal timescales, atmospheric angular momentum, mainly constituted by wind but also pressure effects, is known as the most important driver of Earth rotation variations reflected in those of the length of day. However, in connection with long‐term climatic changes, we additionally anticipate secular trends resulting from shifts or ...

Correcting Non‐Tidal Atmospheric and Oceanic Loading Displacements at the Observation, Normal Equation, and Parameter Levels in GNSS Data Analysis

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Non‐tidal loading (NTL) introduces surface deformation on the Earth and increases the variability in coordinates measured by space geodetic techniques. Correcting NTL displacements in Global Navigation Satellite Systems (GNSS) analysis has been discussed extensively, commonly at the parameter level.

Self‐Assisted First‐Fix Method for A‐BDS Receivers with Medium‐ and Long‐Term Ephemeris Extension

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
As a sensor for standalone position and velocity determination, the BeiDou Navigation Satellite System (BDS) receiver is becoming an important part of the intelligent logistics systems under rapid development in China. The applications in the mass market urgently require the BDS receivers to improve the performance of such functions, that is, shorter ...

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

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 12, December 2024.
Abstract 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. Included in the solution are observations from the Global Positioning System (GPS), Satellite Laser Ranging (SLR) and Very Long Baseline Interferometry (VLBI). A

A determination of the radio-planetary frame tie from comparison of Earth orientation parameters [PDF]

, 1992
The orientation of the reference frame of radio source catalogs relative to that of planetary ephemerides, or 'frame tie,' can be a major systematic error source for interplanetary spacecraft orbit determination.

Proper Motion of Pulsar B1800-21 [PDF]

, 2006
We report high angular resolution, multi-epoch radio observations of the young pulsar PSR B1800-21. Using two pairs of data sets, each pair spanning approximately a ten year period, we calculate the proper motion of the pulsar.

Prospects of Predicting the Polar Motion Based on the Results of the Second Earth Orientation Parameters Prediction Comparison Campaign

Earth and Space Science, Volume 11, Issue 11, November 2024.
Abstract Growing interest in Earth Orientation Parameters (EOP) resulted in various approaches to the EOP prediction algorithms, as well as in the exploitation of distinct input data, including the observed EOP values from various operational data centers and modeled effective angular momentum functions.

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

Journal of Geophysical Research: Solid Earth, Volume 121, Issue 8, Page 6109-6131, August 2016., 2016
Abstract 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 deformation for sites that were subject to major earthquakes.
