Abstract

This article presents results of a comparison of the Russian national UT1–UTC estimation observing program Ru-U and the international IVS Intensive program. It is shown that the Ru-U sessions performed with good accuracy and that the Ru-U results can be included in the international VLBI data processing scheme. A comparison of different distributions shows that the problem of the lack of correlation between single delay formal errors and UT1 estimates are present both in the Ru-U and the IVS Intensive series.
