ROB's operational final GNSS position and tropospheric delay estimates computed in the context of its E-GVAP participation

GNSS-based final positions and tropospheric delays estimated operationally by the Royal Observatory of Belgium (ROB) - Solar-Terrestrial Centre of Excellence (STCE) in the framework of his participation to the EUMETNET EIG GNSS water VApor Program (E-GVAP). These daily precise positions and hourly precise tropospheric delays are computed with a post-processing scheme applied on a very large network of GNSS stations world-wide (as of today 1200+ stations). The final positions are used as station coordinates for estimating tropospheric delays and contribute to E-GVAP. The final tropospheric delay estimates are used for validating ROBS's near real-time, quasi real-time and real-time tropospheic delay estiamtes.
