IGS/EPN Reference Frame Realization in Local GPS Networks
Jarosław Bosy , Bernard Kontny , Andrzej Borkowski
AbstractThe modern geodetic reference systems (e.g. ITRS) are realized by reference frames, i.e. a set of stations with position coordinates at a reference epoch and station velocities (e.g. ITRF2000). IGS (International GNSS Service) global network and EPN (EUREF Permanent Network) regional network stations are parametrized in this way. The main IGS/EPN products (gained daily and weekly) are estimated station coordinates and velocities, as well as orbits’ and ionospheric and tropospheric parameters. The connection of local GPS networks with IGS/EPN stations enables to use the above products. In this publication the method of EPN/IGS reference stations selection for the purpose of local GPS networks is presented. Two approaches are applied: station velocity analysis and cluster analysis. It has also been suggested to process permanent and epoch observations in local GPS networks, which are based on IGS global networks and EPN regional networks’ solutions jointly.
