  3. SRI orientation workshop 2008-09-08 Graz Mariatrost Results Network Analysis • Regional GNSS Data Centre for Europe (1 of 2)‏: 350 Permanent stations + campaign data, comparable to all major DCs worldwide (BKG, CDDIS, GSI, JPL, KASI, SIO, UNAVCO, all 200 -1500 stations)‏ • Analysis Centre: Weekly analysis of 4 networks (50-90 stations each), rank 4 of 16 AC in Europe‏, GNSS antenna + radom field tests (BEV Vienna)‏, Tunnel survey networks (Innsbruck, Koralpe, Semmering)‏ • Products: Coordinates, covariance matrices, troposphere zenith delays, troposphere gradients, basis for realization of the Austrian and European reference frame, weather forecasting, time series, station velocities • Transponder: campaigns on Gavdos, ENVISAT Altimeter Calibration RA-2 Bias: 40 ± 2.2 cm, Height Transfer Accuracy: 2.64 cm

  4. SRI orientation workshop 2008-09-08 Graz Mariatrost Results Geokinematics • Detection and Elimination of Offsets and Outliers from weekly Time Series • Separate influences (equipment, atmosphere, hydrosphere, tectonics)‏ • Generate velocity field • Look for geokinematic patterns (boundary zones, escapements etc) → geokinematical model • Compare to geological and and tectonic information → tectonic model Earthquake at strike-slip fault – permanent offset

  5. SRI orientation workshop 2008-09-08 Graz Mariatrost Results Modeling Regional TEC Maps • Horizontal seasonal variations (atmosphere?)‏ • Thermospheric Neutral Density during Solar Event: • Density ratio of 3-4 of MSIS wrt. CHAMP • Temperature increase up to 4000 K with new model • Near Real Time monitoring prototype • Detection of 3-10 cm outliers Troposphere zenith delays and precipitation phase lag • LEO SLR Data Processing • GPS orbit validation: <2 cm • Gravity field assessment methods

  6. SWOT Analysis

  7. Future Plans to 2013 2008 2009 2010 2011 2012 2013 GOCE Prel. Orbit Val. GOCE Grav. Field Validation Gravity Field from SLR Global Calibration Network Transponder/Altimeter LEO Tailored Models 4D-Ionosphere maps Regional modeling troposphere + ionosphere for positioning and natural disaster research Combination studies geosciences (geodesy, geology, hydrology, meteorology, seismology) for earth surface movements (landslides, earthquakes, elastic deformation) Natural disaster research (hazard zones)

  8. Future Plans to 2013 cont‘d 2008 2009 2010 2011 2012 2013 High Rate (1Hz) and Near Real Time analysis 5 cm level: Station monitoring, weather forecasting, natural disaster research Derivation of physical models at the 1 mm level (antennas, atmosphere, soil, crustal movements) Geodynamic Modeling (=crustal movements + geological models) Regional improvement of global reference systems (GLONASS, velocity field, seasonal variations) Remain at the top of the international geodata infrastructure (GMES, GGOS): requires modernization of web services Continuation of cooperation and setting of standards (IGS, EPN, CERGOP, BEV )

  9. Outlook 2014-2020 2014 2015 2016 2017 2018 2019 2020 Transponder/Altimeter data assimilation, sea level changes, ocean currents LEO model comparison, CME Data Base, model improvements for disturbed conditions 4D-Ionosphere maps Combination studies geosciences (geodesy, geology, hydrology, meteorology, seismology) for earth surface movements (landslides, earthquakes, elastic deformation, permafrost, sediments) Natural disaster research (hazard zones) Near Real Time analysis 1cm level: Station monitoring, weather forecasting, natural disaster research Geodynamic Modeling (strain fields, understanding earthquakes) Global Earth Monitoringand References (GPS, GLONASS, Galileo, LEO, MEO)
