The Vienna Center for VLBI is involved in several projects. To a large extent, these activities are funded and supported by TU Wien and BEV by making it possible that staff members are active in all aspects of VLBI. Additionally, we routinely apply for external funds to extend the portfolio of topics which we could not realize otherwise. In particular, we want to highlight the support by the Austrian Science Fund (FWF) for greatly supporting the VLBI activities since the beginning of the century. More details about a selection of completed and ongoing projects funded by FWF and other agencies (European Space Agency) can be found by using the links below.
