Conclusion and Outlooks
„
„
„
the GPS measurements in the Bohemian Massif
started in 1997 by annual campaigns on regional
geodynamic networks and in 2001 by
observations on permanent stations (GEONAS
network)
relative longlong-term period of the GPS observations
guarantees high accuracy, the standard
deviations of determinations of the horizontal
movements are less then 1 mm/year
the further continuation of the GPS
measurements is necessary to increase the
accuracy of position determinations, especially of
the vertical movements
The end
Thank y
you for yyour attention
