The Current and Future Performance of VGOS
Paper i proceeding, 2023

In this work we investigate the performance of the 24-hour VGOS sessions observed in 2019–2021. We look at the station positions and the Earth Orientation parameters (EOP), and we compare them with the results from the legacy S/X VLBI sessions as well as with simulations. We find that the station position repeatabilities obtained from the VGOS sessions are significantly better than what is obtained from the legacy S/X VLBI sessions. However, the EOP from the VGOS sessions are less accurate than those from the legacy S/X sessions, a consequence of the low number and poor global coverage of the currently operational 
VGOS stations.
