    • CDDIS VLBI level 2 vgosDB format data

    Metadata Updated: February 25, 2025

    This CDDIS collection is composed of geodetic, Very Long Baseline Array (VLBI) level 2 observational and supporting data (including observations, standard deviations, station coordinates, and more) and derived products which are stored and exchanged in a format named vgosDB, which is the International VLBI Service for Geodesy and Astrometry (IVS) standard format for storing, transmitting, and archiving VLBI data. vgosDB datasets are comprised of NetCDF and ASCII files which contain almost all the information that is required to process a single VLBI session (typically 24-hours of data per single session).
