A paper on the computation of global reference frames from very long baseline interferometry (VLBI) observations at the Vienna International VLBI Service for Geodesy and Astrometry (IVS) Analysis Center (VIE) has been published in A&A (here).

The installation of a VLBI transmitter on Galileo satellites would allow observing satellites besides quasars with VLBI telescopes. Three additional Dilution of Precision (DOP) factors were introduced which are representing the sensitivity of a satellite observation towards the components of the satellite position in the local orbital. These factors were used for evaluating observations to […]
