Abstract:

In my talk I will give a general introduction to geodesy and use VLBI to build a bridge between Astrophysics and the interior of the Earth. Since the 1970s Very Long Baseline Interferometry (VLBI) has proven to be a primary space-geodetic technique by determining precise coordinates on the Earth, by monitoring the variable Earth rotation and orientation with highest precision, and by deriving many other parameters of the Earth system. VLBI provides the important link to astronomy through the  determination of very precise coordinates of extragalactic radio sources. But due to its Earth bound stations, it is also linked to the Earth surface, its deformation due to loading, plate tectonics or mechanisms in the Earth interior. I will give an overview over the interactions in the system Earth and its impact on the VLBI observables.
