Reference Frames and Astrometry
Geodesy, astrometry, high precision navigation — all these disciplines require a set of local and global reference frames in an operative sense. Now, it is widely appreciated that this represents not merely a practical but equally well a conceptual problem, which becomes even stronger with the necessity to leave the classical Newtonian framework and to work in a relativistic space-time.
