摘要

The rapid improvement in space-geodetic techniques and their increasing accuracy allows us nowadays to access parameters of theoretical models describing the changes above, on the sur- face, as well as inside the Earth. As a fundamental requirement of a reliable estimation of such parameters stable and consistent reference frames are needed. Module Vie_GLOB of the VLBI analysis software VieVS is introduced which is capable of determining a consistent terrestrial and celestial reference frame together with other parameters of interest. Comparison with offi- cially recognized reference frames is provided and the high quality of the provided VieTRFlOa and VieCRFlOa is presented.
