Circular polarization has indeed been the polarimetry basis in classical VLBI obse rvations. Hence\, conversion of the linear-polarization VGOS visibilities into a pure circular basis allows for a direct application of legacy Geode sy and Astronomy algorithms to VGOS observations.\n\nHere we show how the "PolConvert" algorithm can be used to derive the cross-polarization gains of all VGOS antennas and use it to convert the DiFX products to circular b asis. We also show preliminary broad-band fringe-fitting results and image reconstructions obtained from EU-VGOS observations.\n\nhttps://events.mpi fr-bonn.mpg.de/indico/event/194/session/19/contribution/1 LOCATION:TU Wien Freihaus DC 02 030 "Jupiter" URL:https://events.mpifr-bonn.mpg.de/indico/event/194/session/19/contribut ion/1 END:VEVENT BEGIN:VEVENT SUMMARY:Characterization single dish experiments with NASA VGOS stations DTSTART;VALUE=DATE-TIME:20211028T083000Z DTEND;VALUE=DATE-TIME:20211028T084500Z DTSTAMP;VALUE=DATE-TIME:20260514T105705Z UID:indico-contribution-194-3@cern.ch DESCRIPTION:Speakers: LEONID\, Petrov (NASA GSFC)\nIn order to characteriz e VGOS antenna we have developed\na concept of single dish experiment (SDE ) and software\nthat supports it.

Given the fact that CPU clock speeds have not increased significantly over the last decade\, the only way to achieve this is by parallelizing t he workload. The most efficient way to do this is by eliminating dependen cies between parallel tasks as much as possible.

This functional ity has been successfully used to refine the positions of some of the EVN stations that don't\ntake part in geodetic observation on a regular basis. The aim is also for SFXC to be able to correlate VGOS data. In this con tribution we will present the geodetic capabilities of the SFXC correlator \, focusing on how it differs from the DiFX correlator that is used at oth er correlation centers.

Initia lly the main purpose of these sessions was to test how short VGOS scans ca n be in practice. Our aim was to investigate the suitability of these sess ions for a regular geodetic analysis and an assessment of the quality of t he results.

Any changes in the length of the cable also introduce delays in the pha se calibration signal. The phase calibration correction is applied at the fringe-fitting stage\; therefore\, the instrumental delays from the inject ion point to the sampler are corrected\, and delays due to cable length ch anges of the uplink cable are introduced. The cable delay is measured at t he station by the so-called Cable Delay Measurement System (CDMS)\, or a p roxy is estimated from the phase calibration signal during fringe-fitting (Pcmt). Both delays are stored in the vgosDb file. In this talk\, we prese nt a new feature of the Vienna VLBI Software (VieVS)\, which can select ei ther CDMS or Pcmt to correct the group delays by the cable delays at the g eodetic analysis. Furthermore\, we will show the impact of either using CD MS or Pcmt on the geodetic results of EU-VGOS data.\n\nhttps://events.mpif r-bonn.mpg.de/indico/event/194/session/25/contribution/10 LOCATION:TU Wien Freihaus DC 02 030 "Jupiter" URL:https://events.mpifr-bonn.mpg.de/indico/event/194/session/25/contribut ion/10 END:VEVENT BEGIN:VEVENT SUMMARY:Wettzell station report DTSTART;VALUE=DATE-TIME:20211028T073000Z DTEND;VALUE=DATE-TIME:20211028T074500Z DTSTAMP;VALUE=DATE-TIME:20260514T105705Z UID:indico-contribution-194-13@cern.ch DESCRIPTION:Speakers: Mr. PLÖTZ\, Christian (BKG)\nGeodetic Observatory W ettzell: Current status of the Twin radio telescope Wettzell south (Ws).\n \nhttps://events.mpifr-bonn.mpg.de/indico/event/194/session/15/contributio n/13 LOCATION:TU Wien Freihaus DC 02 030 "Jupiter" URL:https://events.mpifr-bonn.mpg.de/indico/event/194/session/15/contribut ion/13 END:VEVENT BEGIN:VEVENT SUMMARY:Applying PolConvert to EU-VGOS Data DTSTART;VALUE=DATE-TIME:20211028T134500Z DTEND;VALUE=DATE-TIME:20211028T140000Z DTSTAMP;VALUE=DATE-TIME:20260514T105705Z UID:indico-contribution-194-12@cern.ch DESCRIPTION:Speakers: Dr. JARON\, Frederic (TU Wien\, MPIfR)\nVGOS data ar e observed and recorded in dual linear polarization. During the fringe-fit ting process these two polarization directions have to be combined to Stok es I\, taking into account the parallactic angle.

The l ast bigger update was published end of April and was related to integratin g satellite observations. Since then\, development has focused on smaller bug fixes and increased automation for operational use. \nThe next bigger update is planned to incorporate VEX2 support in VieSched++. Currently\, t he use of .skd files instead of .vex files is a significant limitation in geodetic VLBI - especially for VGOS where it is almost impossible to gener ate new schedules without extensive expert knowledge. \nWith the enhanced support of VEX2\, it is required to also define new scheduling catalogs. T he current sked-catalogs have a large number of limitations and several wo rkarounds are necessary for both\, SX and VGOS sessions.
