Astrometry and geodesy with radio interferometry: experiments, models, results
Ojars J. Sovers, John L. Fanselow, Christopher S. Jacobs
Abstract
Summarizes current status of radio interferometry at radio frequencies between Earth-based receivers, for astrometric and geodetic applications. Emphasizes theoretical models of VLBI observables that are required to extract results at the present accuracy levels of 1 cm and 1 nanoradian. Highlights the achievements of VLBI during the past two decades in reference frames, Earth orientation, atmospheric effects on microwave propagation, and relativity.
