ASG-EUPOS Monitoring with Reference to EPN

This paper concerns methods and results of processing of data collected by ASG-EUPOS (Active Geodetic Network - European Position Determination System) sites since the beginning of the system. The elaboration was made by Centre of Applied Geomatics from Military University of Technology and it was based on the experience gained during EPN (European Permanent Network) processing. Strategy was similar to strategy used by EPN Local Analysis Centers for European network elaborations and EPN test reprocessing (Kenyeres et al., 2008). As the outcome daily and weekly solutions (North, East, Up component for each station) were obtained. Basing on weekly solutions local velocities and vertical movements were determined. Preliminary tests of combining national and regional networks were also made and results were compared to official EPN solutions (differences below 1 cm). Daily solutions were analyzed in the context of stability and reliability basing on time series standard deviation.
