VGOS Phase Cal Performance at High Frequencies

Since 2019, VGOS observations have routinely been carried out using the same frequency setup with a range from 3 to 10.7 GHz. Employing a network of European VGOS stations, we carried out experiments testing four alternative frequency setups covering the

Legacy fostering the twins. Connecting the S/X and VGOS telescope network generations [Elektronisk resurs]

With the VLBI Global Observing System (VGOS) being the next step in the development of geodetic Very Long Baseline Interferometry (VLBI), it is necessary to connect the new VGOS network to existing legacy S/X telescopes. Specially designed short-baseline
