Abstract:
The description of the propagation of VLBI signals in the atmosphere is a major error source and needs close attention. While velocities in the ionosphere are frequency-dependent and handled in fringe-fitting with VGOS, propagation delays in the troposphere need to be modelled with the help of zenith delays and gradients. This lecture covers the standard settings and illuminates the expectations with VGOS settings.
