VGOS observing strategy for 202

The VLBI Global Observing System (VGOS) entered operational service in 2020 with a small, northern-hemisphere-dominated network and a modest observing cadence constrained primarily by correlator capacity, data transport, and storage limitations. Since then, the network has continued to expand steadily.

VGOS Source Selection Criteria

2016
Source structure has long been recognized as a significant risk factor for the broadband method. The issue of greatest concern is that structure related phases and delays will lead to cycle slips during broadband phase connection. These errors are subtle to detect and difficult or impossible to correct after the fact.

Fitting of VGOS Data for Astrogeodesy

Source structure modelling of VLBI globalobserving system (VGOS) observations is one of themain interests for Astrogeodesy, a project combiningthe knowledge from geodesy, astrometry and radio as-tronomy. We report our research on the calibration of aVGOS dataset using astronomical data reduction soft-ware.

Microwave radiometer observations for VGOS data processing

Since mid 2023, the Onsala Space Observatory is operating a new modern microwave radiometer, Greta, which is a commercial product of type HATPRO-G5. It is co-located with the other microwave radiometer, Konrad, which has been developed and built at Onsala.
