    3. Paris 20/10/06 Avtive Geodetic Network (AGN) National Geographic Institute (NGI) coordinates all Belgian RTK initiatives within the AGN project NGI - Responsibilities: Integration of all stations in European and National reference system Transformation between ETRS89 and Belgian Lambert Integrity monitoring of all stations Spreading information via dedicated website: http://www.ngi.be/agn/NL/NL0.shtm Full maintenance of one of the three networks

    4. Paris 20/10/06 Flepos FLEmish POsitioning Service Run by AGIV (regional agency) since sept 2002 38 Reference stations on top of buildings

    5. Paris 20/10/06 Walcors WALlonia Continuously Operating Reference Stations Run by MET D432 (Regional agency) since November 2003 23 reference stations on special pillars

    6. Paris 20/10/06 GPSBru GPS-RTK for the Brussels region Run by NGI (federal agency) since October 2002 1 reference station on roof top

    7. Paris 20/10/06 Common aspects of the networks Coordinates of all stations have been determined by NGI in one homogeneous network linked to EPN Same hardware: Leica SR530 receivers + Choke ring antennas (and dome) Real time and postprocessing data are freely available for all users Same mobile phone provider Initial coordinates of all stations are checked weekly by NGI (integrity monitoring)

    8. Paris 20/10/06 Station Integrity monitoring Example of graph with results of weekly computations of the last two years Graphs of all stations are available on the AGN-website
