Time series for more than 600 sources were calculated with using QUASAR software from VLBI data processing. Source positions for every sources were obtained from single series analysis by two ways - with fixed coordinates of all another sources with and without EOP estimation. Time series analysis is performed with covariation analysis technique. The attempt was made to propose the parameter which can be used for selection of stable and unstable sources from analysis of source positions time series.
