  1. EUREF 2013 Symposium National Report of Austria by G. Stangl, N. Höggerl, E. Imrek, D. Ruess, E. Zahn (BEV), H.-P.Ranner (IWF) Budapest, Hungary May 29th to May 31st, 2013

  2. Permanent NetworksAt present 5 : AMON, CERGOP, EPN, GREECE, MON • For reference and geokinematics • Processed according to EPN guidelines • Reprocessing started

  3. APOS – Monitoringstation Innsbruck (INBK ) • height offset vs. realitve humidity • Time series (16th to 23rd of April) of coordinate differences; height offset (red graph) at INBK (university) • (615 m above adriatic sea level) Relative humidity of ZAMG sensor at PATK (2249 m above adriatic sea level) • Relative humidity of ZAMG sensor at INBK (university) • (615 m above adriatic sea level)

  4. 30.793 control points of 1st – 6th order • determined by adjustment of observations • (GPS - baseline, direction, distance, elevation) • 45.780 control points of 6th order • determined by APOS-RTK

  5. Multipath Mitigation DISAP • Testbed at roof with reflectors • Multipath signals tested with Code-carrier and signl/noise ratio • Pre-Test with various antennas and 2 receivers • Main Test with new antenna (moving) in summer 2013

  6. m • Gravity changes in Obergurgl / Tyrol due to ablation of surrounding glaciers • Absolute gravity time series at Obergurgl 1987 - 2009 and cumulative ice-mass balance observations • Oetztal Alps • Ice thickness variation 1997 - 2006 • published: P. Arneitz, B. Meurers, D. Ruess, Ch. Ullrich, J. Abermann, M. Kuhn, 2013: Gravity effect of glacial ablation in the Eastern Alps – observation and modeling. The Cryosphere, 7, 491–498, 2013

  7. Brennerpass1370m • Timmelsjoch 2474m • 2012 status of precise Levelling Loops between Austria (Tirol) and Italy (South Tyrol) and their datum

  8. EVRF Hutbigl • EVRF Hutbigl • 2012 • levelling (BEV) ~90 km • Lev-BBT (cooperation) ~46 km • absolute gravimetry • Beilage 1: Feldarbeit V11/2012 Übersicht • ARLT • TRFB • PFAN • GRAZ • OBGU • Brenner • Timmelsjoch
