Radio Sources Positions Time Series (TS) were analyzed with covariation analysis technique. List of the best and worse sources was used for form the set of sources for NNR constraints. The global solutions with different sets of sources for NNR constraints were obtained. Transformation parameters between this catalogues and ICRF-ext.2 were calculated and compared.
