Latest study of Adriatic microplate over the territory of Republic of Croatia

Comparison of combined solution of Croatian Positioning System (CROPOS) and positioning systems of neighboring countries (Slovenia - SIGNAL, Hungary - GNSSnet.hu and Montenegro - MontePOS), computed from 1741 daily solutions (ETRF2000, e2011.31) for the time span of ~ 5 years with the first adjustment of CROPOS network (GPSW 1506, ETRF2000 (R05), e2008.83) indicates to long-term stability of CROPOS reference frame. Relative kinematic model of Adriatic tectonic microplate CROvel, computed from GPS measurements of CROPOS and nearby positioning systems doesn't show agreement with results of previous researches because this model is calculated for a very short time period, while absolute kinematic model of research area (as a part of Eurasian plate) CRO-2014 shows agreement with global kinematic models and gives a possibility of using this model for point velocity calculation over the territory of Croatia. Geodynamic measuring campaigns allow continuous monitoring of tectonic displacements. Relative kinematic model of Adriatic microplate ADRIAvel, calculated from GPS measurements obtained from 17 geodynamic campaigns (time span of 20 years) shows agreement with results of previous researches, while absolute kinematic model of research area CRODYN-2014 shows agreement with global kinematic models as well and also can be applied for point velocity calculation over the territory of Croatia. Relative kinematic model of Adriatic microplate CroADRIAvel as a result of combination of 1741 daily solutions of CROPOS and nearby positioning systems for time span of ~ 5 years with 17 GPS geodynamic campaigns shows (time span of 20 years) agreement with results of previous researches, while combined absolute model of research area GEODYN-2014 also shows agreement with global kinematic models.
