Abstract

Turkey is located a region where Eurasia,
Anatolia and Arab Tectonic plates intersect. The relative movements of these
plates according each other cause that the locations of the geodetic points
change in cm level per year. For this reason, the changes in the coordinates of
the geodetic points should be monitored continuously and the velocities of
these points should be determined.

 

In this study, the current coordinates and
velocities of Turkish National Permanent GNSS Network- Active (TNPGN-Active)
points which are located at Central Anatolia Region have been determined at
ITRF2008 reference frame and 2005.00 epoch. In the calculation, 11 IGS points
have been selected as benchmark points and GNSS measurements which were
obtained by selecting a day from every week with equal intervals from 2009 to
2015 have been evaluated with using Bernese v5.2 GNSS software. In addition,
the coordinates and velocities of selected points have been obtained from
General Directorate of Land Registry and Cadastre. These have been compared by
the coordinates and velocities calculated by Bernese v5.2 GNSS software.
