Abstract
In the former WISMUT uranium ore mining and processing area (Thuringia Germany) controlling of small surface movements with "cm"-accuracy is required A promising tool is the D-INSAR technology, which could reduce man power spending, compared with other geodetic techniques (GPS, precise leveling). The GeoForschungsZentrum Potsdam (GFZ), the DASA Jena-Optronik company (DJO) and the WISMUT company participate in a joint project (sponsored by the German Space Agency DARA) to apply INSAR in the WISMUT area, using a stable corner reflector (CR) reference net and measuring CRs. The phase difference between the CRs are investigated with the objective to monitor CR movements. The network has been initially positioned by GPS and is also controlled by terrestrial geodetic measurements. Experiments are presently being carried out by shifting CRs out of position. The project status and first results are presented in this paper.
