A new realization of the International Celestial Reference Frame (ICRF) is presented based on the work achieved by a working group of the International Astronomical Union (IAU) mandated for this purpose. This new realization follows the initial realization of the ICRF completed in 1997 and its successor, ICRF2, adopted as a replacement in 2009. The new frame, referred to as ICRF3, is based on nearly 40 years of data acquired by very long baseline interferometry at the standard geodetic and… 

Overview and Status of the International Celestial Reference Frame as Realized by VLBI

Accurate measurement of angular positions on the sky requires a well-defined system of reference that is realized with accessible objects. The purpose of this study is to review the international

Characterizing the astrometric instability of extragalactic radio source positions measured with geodetic VLBI

Context. Geodetic very long baseline interferometry (VLBI) has been used to observe extragalactic radio sources for more than 40 yr. The absolute source positions derived from the VLBI measurements

Imaging Sources in the Third Realization of the International Celestial Reference Frame

The third iteration of the International Celestial Reference Frame (ICRF3) is made up of 4536 quasars observed at S/X bands using very-long-baseline interferometry. These sources are high-redshift

Realization of a multifrequency celestial reference frame through a combination of normal equation systems

Context. We present a celestial reference frame (CRF) based on the combination of independent, multifrequency radio source position catalogs using nearly 40 years of very long baseline interferometry

VLBI Celestial Reference Frames and Assessment with Gaia

The aim of this thesis is to investigate the in uence of modeling and analysis strategies on the celestial reference frame estimated with VLBI with the help of the Gaia reference frame.

The use of astronomy VLBA campaign MOJAVE for geodesy

Investigation of the suitability of the astronomical 15 GHz Very Long Baseline Array (VLBA) observing program MOJAVE-5 for estimation of geodetic parameters, such as station coordinates and Earth orientation parameters concludes that systematic errors in MOJAve-5 dataset are low enough for these data to be used as an excellent testbed for further investigations on the radio source structure effects in geodesy and astrometry.

Unconstrained Estimation of VLBI Global Observing System Station Coordinates

This work calculated VGOS station coordinates based on publicly available VGOS sessions until the end of 2019 while defining the geodetic datum by fixing the Earth orientation parameters and the coordinates of the WESTFORD station in an unconstrained adjustment.

Probing a southern hemisphere VLBI Intensive baseline configuration for UT1 determination

The deviation of Universal Time from atomic time, expressed as UT1−UTC, reflects the irregularities of the Earth rotation speed and is key to precise geodetic applications which depend on the

First VLBI-only TRF/CRF solution based on DGFI-TUM data for ITRF2020

DGFI-TUM is an operational Analysis Cen-ter (AC) of the International VLBI Service for Geodesy and Astrometry (IVS). In this role, we reprocessed almost all VLBI sessions between 1979 and 2020 for

Functional Principal Component Analysis of Radio–Optical Reference Frame Tie

The Gaia optical reference frame is intrinsically undefined with respect to global orientation and spin, so it needs to be anchored in the radio-based International Celestial Reference Frame (ICRF)
