Onsala Space Observatory - IVS Network Station

Report, 2011

During 2010 the Onsala Space Observatory contributed as an IVS Network Station to 27 VLBI sessions organized by the IVS. We used the majority of these sessions to do ultra-rapid dUT1 observations together with our colleagues in Tsukuba. Furthermore, we observed several additional one-baseline ultra-rapid dUT1 sessions. This report briefly summarizes the activities during the year 2010.
