Abstract

We present the state-of-the-art Russian VLBI network “Quasar”. Domestic observations are carried out within the scope of two programs: Ru-U for the operational determination of Universal Time in near real-time and Ru-E for the determination of EOP from 24-hour sessions. Correlation of the data is performed at the IAA correlator ARC. The IAA Analysis Center performs data processing with the QUASAR and OCCAM/GROSS software packages. We show the progress in the EOP determination accuracy after upgrading the registration system to the R1002M DAS developed at IAA.
