Short summary
The precise knowledge of the orientation of an Earth fixed coordinate system with respect to space is of great importance for all tasks of positioning and navigation. In this work we investigated the potential of combining measurements of Very Long Baseline Interferometry and a large ring laser gyroscope to derive highly resolved parameters describing this orientation. The ring laser is not yet at the same level of accuracy and therefore does not substantially influence the results.
