Do you want to know where new VGOS stations would best improve earth orientation parameters? Schartner et al. provide the answer in an article in Earth, Planets and Space.

Finally, we found some time to record new videos for our VieVS YouTube channel. In these videos, all aspects of the VieVS VLBI module are discussed and examples are shown. This covers all major features of the VieVS VLBI software, including: session analysis (fixing clock breaks, removing stations, eliminating outliers…) 24-hour sessions intensive sessions investigating […]

While the physical general assembly of the European Geosciences Union (EGU) in Vienna in the first week in May 2020 was cancelled for the COVID19 pandemic, an event called Sharing Geoscience Onine (SGO) was organized instead. In the mostly text-chat-based sessions, we had several contributions. You can find the displays on EGUSphere and in the […]

The IVS newsletter features, besides other important topics, VGOS correlation activities at TU Wien carried out by Jakob. Enjoy reading!

VieSched++, the new VieVS scheduling module, is used by Matthias Schartner for the generation of VGOS schedules for the International VLBI Service for Geodesy and Astrometry (IVS). Scientific investigations on optimizing VGOS schedules are published in Journal of Geodesy.

On December 17, 2019, Matthias Schartner successfully defended his PhD thesis on scheduling VLBI observations. John Gipson, Axel Nothnagel, and Johannes Böhm challenged him with difficult questions, but Matthias masterfully answered all. Congratulations!

On the occasion of Matthias’ PhD defense, John Gipson from NVI/NASA GSFC visited the Vienna VLBI group. We took the chance to discuss the next steps for the generation of ITRF2020.

On October 22, 2019, Andreas Hellerschmied was awarded the Karl Rinner Award by the Austrian Geodetic Kommission (ÖGK) for the publication on VLBI observations to the APOD satellite in the Journal Sensors in 2018. Congratulations, Andi!

This week, Matthias Schartner is visiting the VLBI group of the NASA Goddard Space Flight Center in Maryland, USA. The main purpose of this trip to demonstrate and teach how to use VieSched++ and VieVS together to generate high-quality VLBI schedules and Monte-Carlo simulations. Additionally, several other people from USNO and Haystack (MIT) took the […]

The third and final day of the VieVS days was devoted to the analysis of VGOS sessions as demonstrated by Markus and the presentation of the VieVS baseband simulator by Jakob. The first VieVS days in our new home – the Freihaus – went very well and will certainly find continuation in 2020.
