Presentation Transcript

  1. SLOVENIAN GPS NETWORK SIGNAL: SLOVENIA-GEODESY-NAVIGATION-LOCATIONDalibor RADOVANGeodetic Institute of Slovenia Ljubljana

  2. SIGNAL • National GPS network under construction • Part of geospatial infrastructure • Main user: Geodesy • Main task: Transition to a new coordinate system • Open to other users: Navigation, facilities management, GIS

  3. NATIONAL COORDINATE SYSTEM • Bessel ellipsoid • Gauss-Krueger projection • Locally deformed classic triangulation – Datum 1948 • Transformation parameters to/from ETRS 89 available for the entire country and locally

  4. NEW COORDINATE SYSTEM National GPS network SIGNAL + Homogenized network of points in ETRS 89 (EUREF campaigns & additional points) + Classic traingulation in transition time

  5. REMINDERSlovenia:20.000 km22.000.000 inhabitants

  6. ORGANIZATION • Surveying and Mapping Authority (SMA) - funds and organization • Geodetic Institute of Slovenia - technical coordination and management (from 2001 on) • 46 SMA branch offices & 150 accredited private companies - execution of geodetic works on local level • Faculty for Civil Engineering & Geodesy - research and consultancy

  7. CURRENT STATUS OF GPS NETWORK • Activities (re)started as late as 2001 • 4 permanent stations + 1 private in networked operation • 1 of them included in EUREF-EPN • Trimble VRS/FKP in operation from the end of 2003 • GPS service in operation at the Geodetic Institute of Slovenia • 50 users • Permanent education system

  8. PLANS • Currently 4 stations in bidding process • Outside SIGNAL: 8 private stations existing (single) • 15 stations planned • Full network until mid 2006 within public-private partnership (SMA + Chamber of private surveying companies)

  9. SIGNAL NETWORK

  10. THE OBJECTIVE • Geodetic accuracy (cm rank)over the whole national territory with 15 stations • Average distance 50 to 70 km • Currently: sub-decimeter accuracy with 5 networked stations • Average distance 70 to 130 km

  11. 2.11 DATA DISTRIBUTION POST PROCESSING • Via web server (SMA's home page) REAL TIME
