1 CROPOS as Support of Geodetic Infrastructure in Croatia Dr. Sc. Danko Markovinović - Croatia CLGE VicePresident The Geodetic Infrastructure in Europe - today and tomorrow Sweden...Umeå June

2 CROPOS CROatian Positioning System The National Network of Reference GNSS stations of the Republic of Croatia putinoperation: 9thofDecember2008. financed under national PHARE2005 program ,00 (source State Geodetic Administration) ,00 75% from EU 25 % State budget Republic of Croatia + Preliminary works

3 CROPOS in CROGeodesy -1 CROPOS is a reference GNSS network of permanent stations of the Republic of Croatia provides for its users the real time positioning with an accuracy of ±2 cm for horizontal positioning (2D) and ±4 cm for vertical positioning(3d) duetothefullcropossystemfunctionalityfromthe end of the 2008 th, the approach to the monitoring of geodetic infrastructure was fundamentally changed 3

4 CROPOS in CROGeodesy -2 Represents new step forward, impulse and power for: geodesy economy establishment and maintenance of geoinformation new vision and way of communication it is intended for proffesional and scientific users of: geodetic- cadastral system of Croatia state and local government public sectors and institutions economy citizens(hikers, car navigation, nautics, climbers...) 4

5 CROPOS in CROGeodesy -3 homogenization of coordinate system introduction and application of new geodetic reference system(datum) of the Republic of Croatia unique measurements and positioning accuracy on the entire territory of the Republic of Croatia utilization of the unique measurement methods standardization in geodetic works faster, economic and more efficient performance of geodetic works 5

6 Distribution of permanent stations SLO - 7 H stations Mutual distance <70 km Network software: Trimble MN - 2 6

7 CROPOS System Charasteristics Collecting the data from 30 reference GNSS stations Measurement data exchange between reference GNSS stations and the neighboring countries in real time Networking and computing the correction parameters in real time Distribution of measurement data and correction parameters totheusersinrealtime Distribution of measurement data to the users for postprocessing Monitoring the system operations and providing support to the users For scientific purposes: Bernese software /7 system availability 7

23 Conclusion - 1 Stability, reliability and accuracy of CROPOS ensures strong support for geodetic infrastucture in Croatia The application and implementation of a unique transformation model in the CROPOS system gives a new dimension and quality when monitoring spatial data The implementation of CROPOS system has greatly facilitated monitoring and recording of geodetic infrastructure with the results giving important support and guidelines in improving economy, the work in public governmental institutions, environmental aspect of the geodetic work and other daily situations in life and work 23

24 Conclusion - 2 ACCURACY AND EFFICIENCY homogenous measurements on the whole area of Croatia unique accuracy of 2D and 3D positioning RELIABILITY aviliability on the entire area (limitations due to the mobile operators) continuous high technological quality of the whole system education and scientific/ proffesional progress for people that manage the CROPOS system information and support to the users (symposiums, workshops, lectures, notifications and newsletter) ECONOMIC time saver in gathering the data people saver in field work cost effective pricing model for CROPOS service 24

25 Conclusion - 3 FUTURE PROSPECTS Cadastral survey Densifying of Gravity Network of II.order Height transmission on the islands International cooperation - geodynamical investigation - tectonic Investigation of the earthquakes Sea level changes Precise leveling network (position + gravity) Detailed survey of: highways railways agriculuture viaducts displacements and strains monitoring tunnels 25
