International VLBI Service for Geodesy and Astrometry
Project DescriptionThe International VLBI Service for Geodesy and Astrometry (IVS) was established in February 1999 in order to support VLBI programs for geodetic geophysical and astrometric research and operational activities. The objectives of the IVS are to provide a service to support geodetic, geophysical, and astrometric research and operational activities, to promote research and development for VLBI, to integrate VLBI into a global Earth observing system, and to interact with users of VLBI products. The IVS coordinates the observations, the data flow, the correlation, the data analysis, and the technology developments. Products generated by the IVS contribute to research in many areas, including solid Earth, tides, studies of the vertical, fundamental astronomy, and VLBI technique improvement.
