Abstract

A global solution has been made as a result of the VLBI observations which took place from 1979 to 2019 with the purpose to create an improved version of the celestial coordinate system. Coordinates of the radio sources and stations were chosen to be the global parameters, and the EOP data were considered to be the local parameters respectively. The station clock desynchronisation parameters and the wet component of the tropospheric delays were accounted as the stochastic signals when the mean squares collocation method was used. The updated catalogue was compared with the catalogues of other centers and with the ICRF3.
