The impact of the AuScope VLBI observations and the regional AUSTRAL sessions on the TRF [PDF]
The AuScope VLBI array was built with the purpose to improve the terrestrial (TRF) and celestial reference frames in the southern hemisphere. Since 2010 the three 12-m antennas in Hobart (Tasmania), Katherine (Northern Territory) and Yarragadee (Western ...

Observations of Artificial Radio Sources within the Framework of Geodetic Very Long Baseline Interferometry [PDF]
Very long baseline interferometry (VLBI) is a mature and fascinating technique with unique and indisputable applications in radio astronomy, planetary sciences, and space geodesy. The latter discipline is a field of science facilitating our understanding

Gravitational deformation of ring-focus antennas for VGOS: first investigations at the Onsala twin telescopes project [PDF]
The receiving properties of radio telescopes used in geodetic and astrometric very long baseline interferometry (VLBI) depend on the surface quality and stability of the main reflector.

How to register a VGOS radio telescope at ITU and why it is important [PDF]
VGOS radio telescopes enable observations in the range of 2-14 GHz and are much more receptive for unwanted radio frequency interference. Some space-borne transmitters may cause detrimental radiation to VGOS receivers.

The impacts of source structure on geodetic parameters demonstrated by the radio source 3C371
Closure quantities measured by very long baseline interferometry (VLBI) observations are independent of instrumental and propagation instabilities and antenna gain factors, but are sensitive to source structure.

VGOS VLBI Intensives between MACGO12M and WETTZ13S for the rapid determination of UT1-UTC
In this work, we present a status update and results of the designated research and development VLBI Intensive program VGOS-INT-S, observed between MACGO12M and WETTZ13S for the rapid determination of the Earth's phase of rotation, expressed via UT1-UTC.
