"INT9 - dUT1 determination between the geodetic observatories AGGO and Wettzell";
Talk: 24th Meeting of the European VLBI Group for Geodesy and Astrometry, Gran Canaria, Spain; 2019-03-17 - 2019-03-19.



English abstract:
The AGGO radio telescope, located at La Plata in Argentina, comprises together with the radio telescopes in Wettzell, Germany a baseline configuration spanning a longitude difference of 71. Therefore, mid of 2018, tests were initiated to prove the usability for dUT1 determination between the legacy S/X VLBI systems at AGGO and Wettzell. The 6 m AGGO radio telescope was either with the 20 m radio telescope Wettzell (Wz) or with the 13.2 m Wettzell North TWIN1 (Wn) in almost weekly VLBI tests for UT1 determination, named INT9, scheduled. The scheduling of INT9 was done with sked and the time duration was set to be 2 hours each. The sessions were conducted mostly on Thursday just before the INT1 Intensive session takes place. The recording mode needed to be evaluated step by step to increase gradually from a standard 256 MBit/s recording mode to 1 Gbit/s. The latter mode yields a higher amount of scans in a given time period. The goal is to exploit the highest dUT1 determination accuracy between AGGO and Wettzell as possible. We will report our experiences with the VLBI operation at both observatories and compare first results between official UT1 measurements and the INT9 derived values as well as a potential future outlook of this INT9 VLBI application
