VLBI observations for the last 25 years will be used for new revision of the International Celestial Reference Frame (ICRF), the International Terrestrial Reference Frame (ITRF) and the IERS Earth's Orientation Parameters (EOP) with the help of a new software QUASAR (Quantitative Analysis and Series Adjustment in Radioastrometry). The package QUASAR allows to compute the residuals (O-C) according to IERS Conventions (2003) and to analyze their by single-/multi-series or global adjustment using parametric, stochastic and dynamical models of data.
