During the year 2000, the first two GPS-permanent stations in the
Republic of Croatia were established: Dubrovnik and Osijek. These
stations became the part of two international networks designed for
monitoring Earth's crustal movements: EUREF-Permanent and International
GPS-service for Geodynamics. In this paper we describe the background of
the IGS and EUREF Permanent projects, basic tectonic patterns of the
Adriatic Microplate, establishment of permanent stations in Croatia,
performed measurements, and the first results of their usage. In
addition, a proposal for development of a Croatian GPS-permanent
stations network is given. Such a network could be used for both
numerous scientific investigations and practical real-time navigation on
the land, at the sea and in air.
