Chapter 7 Conclusions and Outlook

摘要

VLBI satellite tracking is a new technique involving the potential to support a consistent derivation of precise reference frames. Appointing adequate observing strategies, that enable the precise determination of station coordinates in the satellite system,is an important step towards this final goal. As illustrated in figure 7.1,such antenna positions in the satellite system can further on be directly compared to that in the VLBI system,determined through classical observations to radio sources. Possible deviations of the two sets of coordinates would then represent the frame tie between the frame of the satellite and the VLBI frame. Determined at
