Monitoring Earth rotation with Very Long Baseline Interferometry ( VLBI) has unique potential because of direct access to the Celestial Reference System (CRF and Terrestrial Reference System (TRF) and the feasibility of re-analyzing the entire data set. The combined results become accessible on the VNIIFTRI server () approximately at 6h UT daily. The EOP values are weekly refined and systematic errors of every individual series are corrected. Joint processing of these 7 series is carried out every day (the operational EOP data for the last day and the predicted values for 50 days). To these three series of EOP the data calculated in two other Russian analysis centers are added: IAA ( VLBI, GPS and SLR series) and MCC (SLR). The observations of GLONASS and GPS on 30 stations in Russia, and also the Russian and worldwide observations data of VLBI (35 stations) and SLR (20 stations) are used now. Russian State Time, Frequency and Earth Rotation Service provides the official EOP data and time for use in scientific, technical and metrological works in Russia. Russian State Time and Earth Rotation Service: Observations, Eop Series, Prediction Here we present the methodology and first results of Kalman filtered EOP from VLBI data. The goal is to implement it in the GFZ version of the Vienna VLBI Software (VieVS) as a completely automated tool, i.e., with no need for human interaction. Project VLBI-ART contributes to these objectives by implementing an elaborate Kalman filter, which represents a perfect tool for analyzing VLBI data in quasi real-time. With the launch of this next generation VLBI system, the International VLBI Service for Geodesy and Astrometry (IVS) increased its efforts not only to reach 1 mm accuracy on a global scale but also to reduce the time span between the collection of VLBI observations and the availability of the final results substantially. One of the goals of VGOS ( VLBI Global Observing System) is to provide such near real-time ERP. They also allow the precise tracking of interplanetary spacecraft. For applications such as satellite-based navigation and positioning, accurate and continuous ERP obtained in near real-time are essential.

Geodetic Very Long Baseline Interferometry ( VLBI) is one of the primary space geodetic techniques, providing the full set of Earth Orientation Parameters ( EOP), and it is unique for observing long term Universal Time (UT1). ERP Estimation using a Kalman Filter in VLBI
