Usage and upgrade of the Croatian Positioning System - CROPOS

The Republic of Croatia launched its GNSS positioning system – CROPOS in December 2008. In just two years after its launch, the CROPOS system has found its wide application in the field of geodesy, cadastre and other economic branches in Croatia. According to the system use indicators, in the past two years CROPOS has been used more than the networks in the neighboring, larger and better populated countries. The reasons for this are higher quality and reliability of the system on the one hand and in a reasonable pricing policy on the other hand, as well as in continuous system upgrade. This paper describes the indicators of quality, reliability and system use volumes while the financial effects of its use have been derived from the pricing policy. Subsequently, preparing the framework for the transfer onto the new Croatian referential framework and mapping projections in practice, the paper shows system upgrade activities undertaken during the two years of the CROPOS functioning as well as the effects that it has yielded or is expected to yield. Special emphasis with regards to the system upgrade is put on the development of a universal transformation model and its integration into the CROPOS system with the help of a transformation generator and operations implemented by the State Geodetic Administration with the objective of implementing the transformation model. Finally, the paper offers perspectives of the CROPOS system future development and its role in the implementation of the new Croatian referential framework and mapping projections.
