Next works have been spent: Support of functioning of stations UKRGEOSPACENET; Support of programs of observations of stations UKRGEOSPACENET; It was spent analyze of observations of stations of a space geodesy and geodynamics; Works concerning a laser location were spent; Information-technical support of the Ukrainian centre of definition of parameters of rotation of the Earth. Thanks to the spent works Ukraine took participation in the international cooperation from creation, support and metrological certification of two basic systems of coordinates (ICRS and ITRS) and their realizations(ICRF and ITRF). The scale of Universal time was supported and pole coordinates were defined. Works on improvement of system of transmission of exact time to consumers by means of the Internet were spent.
