It was carried out observation at CRIMEA in the IVS network simultaneously with Russian VLBI-stations. A VLBI data processing software SteelBreeze was updated to be able to process Russian-Ukrainian VLBI observations. The EOPs were estimated and new high-accuracy realization of Celestial and Terrestrial Reference Frames were obtained using this software. To refine defining radio sources list it was obtained improved positions and investigated stability of selected radio sources. When obtained new realization of Terrestrial Reference Frame the coordinates and velocities of CRIMEA station were refined. The coordinates were obtained with r.m.s. at the few millimeters and velocities with r.m.s. about few mm per year. Product Description popup.authors popup.nrat_date 2020-04-02 Close
