  1. EUREF 2012 Symposium National Report of Austria by Günter Stangl, Norbert Höggerl, Jürgen Otter, Diethard Ruess, Ernst Zahn (BEV) Sandro Krauss, H.-P.Ranner (IWF) Saint Mandé, France June 6th to June 8th, 2012

  2. Permanent GNSS-Networks Cooperation between BEV and OLG Observatory Lustbühel/Graz 5 Networks: EPN – Subnetwork (80 stations) MON - Eastern Medit./Arabian Plate (65 stations) CERGOP – Central European Geodynamic Network (80 stations) AMON - Austrian Monitoring (85 stations) GREC – Greek testbed for ionosphere, earthquakes and geokinematics (60 stations) AMON08 solution: Base for the whole national realization of ETRS89 in AUSTRIA Check for Lifetime: AMON horizontal velocities ETRF2000 from cumulated time series 1999-2012

  3. ETRS89 HORTH = HELL – NGRS80 Height in Use (MGI)HGEBR Correction value Grid 1 Grid 2 = (HNORM – HGEBR) + (HORTH – HNORM) HORTH – HGEBR Transformation Grid between Horth and HGEBR (Height-Grid) • Used for laser scanning data • Advantages: homogeneous for the entire area (Austria)

  4. Grid 1: Modelling of Differences HNORM - HGEBR • different tide gauges: about -30cm • use of levelling results • no correlation with elevation Grid 2: Modelling of Differences HORTH – HNORM ~ • 53.000 g-values (surface) • use of interpolated g-Values (Bouguer-map): 50.800 control points 47.200 levelling points 358.000 grid points of DTM (500m) • correlation with elevation

  5. Resulting Height Grid = Grid 1 + Grid 2 • GRID ,  (MGI) • Grid width 15“x22.5“ (≈ 500 x 500 m) • Precision of transformation < 5 cm

  6. Gravity European Comparison of AG in Walferdange ECAG 2011: Austria participated with FG5-242 in the Key Comparison EURAMET.M.G-K1 AG-Meeting in Vienna, BEV, February 2012: JWG 2.1-Techniques and Metrology in AG and JWG 2.2-Absolute Gravimetry and Absolute Gravity Reference System Build-up of a gravity base network in Italy/ Autonomous Province Bozen: 6 stations Walferdange/Luxemburg Gravity Base network Province Bozen/Italy
