Review of radio astrometry II. Optical measurements

International Astronomical Union Colloquium, 1978
The establishment of an astronomical reference frame which is based on positions of extragalactic objects is an old problem of fundamental astronomy. Radio astrometry has now achieved a level of accuracy, which rivals the best optical work, thus openingexcitingprospects to reach this aim within a relatively short time scale.To take full advantage of ...

Advances in Astrometry and Geophysics Made Possible by Radio Interferometry

1998
Abstract : Radio Interferometry has had a tremendous impact on the development of astrometry and geodesy. Barry Clark has played a leading role in developing the technology of radio interferometry through his work on connected-element interferometry, i.e., the Green Bank Interferometer and Very Large Array; and VLBI, i.e., the Mark I and II VLBI ...
