Activities of the Department

Activity of the Department of Geodetic Measuring Technology is in close relation with the activities of Department of Mathematical Geodesy and Department of Physical Geodesy. Our research themes are the followings.

 1. Investigation of global geodynamic processes

 Studying tidal phenomena of the Earth and the atmosphere, as well as related geodynamic processes;

Studying tectonic processes in the Pannonian Basin on the basis of extensometric measurements (in the frame of international cooperation with Slovakia, the Czech Republic and Russia);

Development of instruments and calibration procedures necessary for our research activity;

Development of mathematical methods for data processing and evaluation;

Data processing of the registered data and their interpretation from point of geodynamics (Earth and atmospheric tides, inner structure of the Earth, tectonic movements, polar motion, earthquake formation investigations, etc.);

Investigation of local environmental effects on geodynamic measurements and elaboration of methods to filter out or to take them into account in the course of data processing and evaluation.

 

Our measurement activity in connections with research:

 

Earth’s tide and crustal movement registration by means of a quartz-tube extensometer in the Geodynamical Observatory of Sopron;

Monitoring recent tectonic processes with extensometers in the Pannonian Basin in the frame of international cooperation (Slovakia, the Czech Republic and Russia);

Parallel atmospheric tide registration in the Geodynamical Observatory of Sopron and in the Sashegy Earthquake Recording Observatory.

 

2. Investigation of local geodynamic phenomena

 

Kinematic investigation of fissures with borehole tiltmeters;

Investigation of surface mass movements with borehole tiltmeters;

Investigation of possible connections between ground tilt and ground water fluctuations.

 

3. Research in the field of engineering surveying

 

Investigation of connections between building- and ground motions;

Measurement techniques and interpretation methods development;

Monitoring industrial establishments’ deformations and motions.

 

4. Calibration of instruments

 

Calibration of geodetic instruments (level instruments, theodolites);

Calibrations of geodynamic instruments in laboratory and in-situ (observatory).
