About the paper

Abstract

Regular observations for determinations of Earth orientation parameters have been performed by the Russian VLBI network "Quasar" since August 2006. The observations are carried out weekly in the framework of two national programs: 24-hour sessions for determination of all EOP from observations on the "Quasar" network (Ru-E program) and 1-hour sessions for UT1 determination at "Zelenchukskaya" - "Badary" baseline (Ru-U program) using e-VLBI data transfer. EOP accuracy for 2011 observations from Ru-E sessions is about 1 mas for polar coordinates, 37s for dUT1, and 0.46 mas for Celestial Pole coordinates. Accuracy of dUT1 from Ru-U sessions is about 56 s. The results are available in 2-3 hours after the beginning of Ru-U sessions and in 2-3 days after Ru-E sessions.
