GENESIS: Co-location of Geodetic Techniques in Space
Pacôme Delva, Zuheir Altamimi, Alejandro Blazquez +39
Improving and homogenizing time and space reference systems on Earth and, more directly, realizing the Terrestrial Reference Frame (TRF) with an accuracy of 1mm and a long-term sta…
Impacts of the image alignment over frequency for VLBI Global Observing System
Ming H. Xu, Tuomas Savolainen, James M. Anderson +4
The VLBI Global Observing System, which is the next generation of geodetic VLBI and is called VGOS, observes simultaneously at four frequency bands in the range 3.0--10.7 GHz (expe…
Observable quality assessment of broadband very long baseline interferometry system
Ming H. Xu, James M. Anderson, Robert Heinkelmann +3
The next-generation, broadband geodetic very long baseline interferometry system, named VGOS, is developing its global network, and VGOS networks with a small size of 3--7 stations…
Evidence of the --VLBI position differences being related to radio source structure
Ming H. Xu, Susanne Lunz, James M. Anderson +3
We report the relationship between the --VLBI position differences and the magnitudes of source structure effects in VLBI observations. Because the --VLBI position diff…
The impacts of source structure on geodetic parameters demonstrated by the radio source 3C371
Ming H. Xu, Robert Heinkelmann, James M. Anderson +4
Closure quantities measured by very long baseline interferometry (VLBI) observations are independent of instrumental and propagation instabilities and antenna gain factors, but are…
The source structure of 0642+449 detected from the CONT14 observations
Ming H. Xu, Robert Heinkelmann, James M. Anderson +3
The CONT14 campaign with state-of-the-art VLBI data has observed the source 0642+449 with about one thousand observables each day during a continuous observing period of fifteen da…
Interaction between celestial and terrestrial reference frames and some considerations for the next VLBI-based ICRF
Zinovy Malkin, Harald Schuh, Chopo Ma +1
In this paper we outline several problems related to the realization of the international celestial and terrestrial reference frames ICRF and ITRF at the millimeter level of accura…
Free Core Nutation observed by VLBI
Hana Krásná, Johannes Böhm, Harald Schuh
The signature of free core nutation (FCN) is found in the motion of the celestial intermediate pole in the celestial reference frame and in the resonance behaviour of the frequency…
Analysis and comparison of precise long-term nutation series, strictly determined with OCCAM 6.1 VLBI software
G. Bourda, J. Boehm, R. Heinkelmann +1
The IAU/IUGG Working Group on "Nutation for a non-rigid Earth", led by Véronique Dehant, won the European Descartes Prize in 2003, for its work developing a new model for the prece…
