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



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



NEW COORDINATE SYSTEM

National GPS network SIGNAL+

Homogenized network of points in ETRS 89 (EUREF campaigns & additional points)

+Classic traingulation in transition time



REMINDER

Slovenia:20.000 km2

2.000.000 inhabitants



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



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



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)



SIGNAL NETWORKSIGNAL NETWORK



• 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
