  1. The CEGRN 2011 Campaign and the densificationof ETRF2000 in CentralEurope A. Caporali, M. Barlik, M. Becker, L. Gerhatova, G. Grenerczy, J. Hefty, A. Krauss, P. Legovini, D. Medac, G. Milev, M. Mojzes, M. Mulic, O. Odalovic, T. Rus, J. Simek, J. Sledzinski, G. Stangl, B. Stopar, F. Vespe, and G. Virag EUG 2012 Session G6.3

  2. Outline • Main Objectives • Structure • Data Flow • Network • Data baseandCampaigns • CEGRN vs. IGS and EPN • Tectonicsetting • Results • Conclusionsandoutlook

  3. Main Objectives Modelling of regional intra-plate 3D velocity field at millimetre level Combination of solutions of individual analysis centres Combination of repeated epoch networks, coordinate and velocity estimates Evaluation of accuracy and reliability of obtained information Velocity maps, regular grid velocities, deformations, geo-kinematical interpretations Evaluation of statistical significance of derived quantities Visualisation of products, geo-kinematical maps Strain analysis and detection of velocity changes for dynamical investigations and special study areas with national or regional densification networks

  4. CEGRN Structure CEGRN ConsortiumGoverning Board CCGB Consortium Secretariat Participating Institutes CEGRN Network sites and Host Institutes CEGRNData Center CEGRNProcessing Centres USER COMMUNITY Project Study Groups, Universities, Res. Institutes, Organizations

  5. RAW(Binary) DATA From Epoch Stations Log-Sheets IGS/EPN Permanent Stations CERGOP DATA CENTER OLG/ GRAZ RINEX DATA Epoch Stations VALIDATION CERGOP - Analysis Center UPA STU SGO WUT ASI GOP OLG Combination, velocity Field Study Group 5 Reference Frame StudyGroups CEGRN Data Flow CEGRN Non-EPN Permanent Stations

  6. CEGRN – General+Network International: CEI (Central European Initiative) 11 Countries: Austria, Bulgaria, Croatia, Czech Republic, Germany, Hungary, Italy, Poland, Slovakia, Ukraine. CEGRN 2011: CEI Countries + 3 Countries : Bosnia Herzegovina, Rumania, Serbia.

  7. The CERGOP2 database • CEGRN campaign information (maps, equipment, observed stations), • ftp access to observations • Epoch solutions of the campaigns (SINEX) • daily and hourly RINEX files of the non-EPN permanent stations • links to work packages and the CEGRN Consortium • Public and Project area Tectonic Settings

  8. CEGRN GPS Campaigns CEGRN Campaigns

  9. CERGOP-2 Network fits into IGS + EPN

  10. Tectonic setting Tectonic Settings

  11. 2011 results (ITRF2008 and ETRF2000) Horizontal

  12. Timeseriesof Minimum Constraintstations (1/2) (Translation in position and velocity)

  13. TimeSeriesof MC Stations (2/2)

  14. New Challanges • The newchallangesof CEGRN focus on Science and Applications • Science: • support the IAG project on Dense VelocityFieldsbyprovidingEpochSinexfilesresultingfromstate-of-the-art processing standards (IGS-EPN guidelines) • Geokinematicalinterpretationof the velocityfield (TopoEurope project, Wegener) and characterizationofareassubjectto the largestdeformation (Balkans, Dinarids, Vrancea, EasternAlps) • Applications (direct relation to FP7/FP8 Calls) • INSPIRE: the CEGRN network can serve asgeospatialinfrastructureforharmonizationofgeodeticstandardsacrossEurope • NEREUS (Network ofEuropeanRegionsUsing Space Technologies): hasone WG on GNSS and one on GMES; powerful lobby in Brussels • EUPOS: requiresstationswith high qualification and trainedpersonnel • Emergingnetworks: ALBPOS (G.Stangl’s baby!)

  15. Summary and Outlook • Unique Reference frame – blendof Permanent andEpochstations • (Intra-) Plate velocitiesatthe < 0.5 mm/yrlevel • Re-Processing withITRF2008 and Absolute Antenna Phase Centers • Present tectonics in Central and SE Europe:crustal motion, deformation, strain accumulation • CEGRN isplanningcontinuation in newframes / projects: • GNSS + Seismology • GMES – Environment and Security • Potential cooperation: • Densificationof ITRF2005 + DenseVelocity Field in Europe • Topoeurope, Geohazard • INSPIRE, NEREUS FP7/8 • EUPOS • WEGENER GEODAC – Database Grenerczy, CERGOP-2, W.P10.3
