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 […]

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!

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.

The second day of the VieVS days is dedicated to scheduling with VieSched++. Matthias explains the intricacies of scheduling with his easy-to-use software package.

Jakob, Jamie and Johannes used the chance and visited the Vienna Scientific Cluster 4 (VSC-4) where we will use 10 private nodes for VLBI correlation. We are still waiting for the storage to get started.

On September 10, 2019, Markus Mikschi presented his bachelor thesis on the integration of length-of-day values for the determination of UT1. Depending on the calibration, it is possible to achieve an accuracy of 40 microseconds after a week. It should also be noted here, that his presentation was the last one in our “old meeting […]

On 22 August 2019, four colleagues from the Beijing Aerospace Control Center (BACC) visited us at TU Wien to inform each other about research focus points and to discuss possible future co-operation activities.
