VGOS data are observed and recorded in dual linear polarization. During the fringe-fitting process these two polarization directions have to be combined to Stokes I, taking into account the parallactic angle. Before the visibilites can be coherently added, the cross-polarization complex gains for each telescope have to be determined in a calibration step. In this talk I show how PolConvert can be

In order to achieve the VGOS goals, the correlator capacity will have to be scaled up significantly. Given the fact that CPU clock speeds have not increased significantly over the last decade, the only way to achieve this is by parallelizing the workload. The most efficient way to do this is by eliminating dependencies between parallel tasks as much as possible. In this contribution I will disc

The calibration and imaging of VLBI observations in circular polarization basis is preferred, since the parallactic-angle correction reduced to a simple deterministic phase correction that commutes with all antenna-gain corrections. Circular polarization has indeed been the polarimetry basis in classical VLBI observations. Hence, conversion of the linear-polarization VGOS visibilities into a pure

While the SFXC correlator at JIVE is (currently) not a VGOS correlator, it has in recent years gained the capability to function as a geodetic correlator. This functionality has been successfully used to refine the positions of some of the EVN stations that don't
take part in geodetic observation on a regular basis. The aim is also for SFXC to be able to correlate VGOS data. In this contributi
