At TU Wien we can independently conduct a VLBI experiment from start to finish. A VLBI experiment can be split into four tasks. First the experiment has to be planned, also called scheduling. In our Scheduling Center the state of the art scheduling tool VieSched++ that was developed at TU Wien is used for this task. The second step is observing the session. Obviously this has to be done by the antennas and their ground staff. In the third step the recorded data has to be correlated. In Vienna we have access to the Vienna Scientific Cluster (VSC) which is one of the most powerful supercomputers in the world. We use this resource to correlate VLBI sessions within the Correlation Center. The correlated data is then analysed in the fourth step. The Analysis Center, which is operated by TU Wien and the Federal Office of Metrology and Surveying (Bundesamt für Eich- und Vermessungswesen, BEV), utilizes the state of the art Vienna VLBI and Satellite Software (VieVS), which is developed at TU Wien.
The ability to conduct a whole VLBI experiment from start to finish with software that was mostly developed in house provides unique possibilities for the Vienna VLBI Center which are only matched by a few other institutions on the globe.
