The results were delivered to the International correlation processing center in Bonn and the board of the Ukrainian network of space geodesy stations. Routine processing of the International VLBI service took place and analysis of the results with the purpose to determine the coordinates of the extragalactic sources (Celestial reference frame realization), coordinates and velocities of the Earth's located observing stations (Terrestrial reference frame realization) and the Earth's orientation parameters. The observations of the Ukrainian-Russian VLBI network (three Russian radiotelescopes in Badary, Svetloe and Zelenchuk and the single Ukrainian in Simeiz) were processed too. Collection and archiving of the data from Ukrainian-Russian laser and navigation networks were continued. The preparation to joint analysis of the data from different methods was made.
