Application of Scientific Software GAMIT/GLOBK for Geodynamics in Bosnia and Herzegovina
Global Navigation Satellite Systems (GNSS) are used for different purposes in geodesy, like engineering geodesy, land management, real estate cadastre, land surveying, etc. However, high-precision GNSS measurements are used primarly for determination of reference networks, and for investigation of geodynamical phenomena as tectonic plates movements, which is the focus of this paper. An active GNSS network of Bosnia and Herzegovina (BIHPOS) was used for calculation of coordinates and velocities of networks' stations. Data from 23 stations were processed using scientific software GAMIT/GLOBK (version 10.7), developed on MIT (Massachusetts Institute of Technology). A sub-centimeter accuracy of coordinates is achieved and accuracy of calculated velocities is better than 1 mm/year. Station velocities interpretate geodynamics of Bosnia and Herzegovina. Six IGS stations were used, as reference datum stations. Reference stations analysis results are in good match with EUREF Permanent GNSS Network velocities, while BIHPOS stations velocities (at 13 stations in Bosnia and Herzegovina) show very similar trend to the velocities obtained from regional geodynamic campaigns (CERGOP).
