Towards the Establishment of New Gravity Control in Poland

The existing Polish gravity control (POGK) was established in the last few years of twentieth century (Sas-Uhrynowski et al. (A new national gravity control network—POGK97 (in Polish). Proceedings of the Institute of Geodesy and Cartography, 1999); Sas-Uhrynowski et al. (A new gravimetric control network for Poland. Reports on Geodesy, 2000)) according to the international standards (Boedecker (BGI Bull d’Inf 63:51–56, 1988)). It is based on 12 absolute gravity stations surveyed with four different types of absolute gravimeters. Relative measurements performed by various groups on nearly 350 points with the use of LaCoste & Romberg (LCR) gravimeters were linked to those 12 stations.

Geodetic and Geodynamic Studies at Department of Geodesy and Geodetic Astronomy Wut

Abstract The article presents current issues and research work conducted in the Department of Geodesy and Geodetic Astronomy at the Faculty of Geodesy and Cartography at Warsaw University of Technology. It contains the most important directions of research in the fields of physical geodesy, satellite measurement techniques, GNSS meteorology, geodynamic studies, electronic measurement techniques and terrain information systems.

Variation of Point Positions and Gravity Field in the Area of Intensive Mining

The results of periodic satellite GPS and gravimetric measurements accomplished in the area of intensive mining near Wodzislaw Slash (Upper Silesia Region) are reported in the paper. Procedures of establishing GPS control networks in this kind of areas are discussed. Changes of gravity Bouguer anomalies and displacements of surface points are shown as a complement of the mining exploitation data.

Geodynamic Studies in the Polish Part of the Teisseyre-Tornquist Zone

Geologic structure of Central Europe is characterized by three main types of geotectonic units . They are: Paleozoic folds in western and south-western part of Europe (West European Paleozoic Platform), the oldest geologic unit — East European Precambrian Platform and the Alpine Orogeny in the southern part of Europe. It is easy to recognize that all these three geotectonic units just meet on the territory of Poland forming in southeastern part of Poland so called “tectonic knot”. The general scheme of tectonic units occurring on the territory of Poland based on results of deep seismic soundings can be seen in Fig. 1. The arrows show directions in which Moho discontinuity increases. It can be also seen that Poland is cut by Teisseyre-Tornquist’s zone, i.e. by the border between Paleozoic Platform and Precambrian Platform.
