The paper presents the results of geodyn amic research in the fram e of the project COST 625 relating to active tectonic structures’ monitoring on the selected areas in Poland, Italy and Greece. Research was realised using a self-developed control and measurement system. The resu lts of researches for period 2000-2006 indi cate slight movements of observatio n points in the Sudety Mts. reaching several millimetres. However, the results confirm recent mobility of tectonic structures o f this area. Research realised in the Mediterranean Region objects - Gargano, Norcia (Italy) and Kaparelli (Greece) - indicate movements of observation points reaching over a dozen millimetres, particularly on the Gargano area. Continuation of cyclic control measurements on these objects is fully justified ., Stefan Cacoń, Bernard Kontny and Jarosław Bosy., and Obsahuje bibliografické odkazy
GNSS meteorology is the remote sensing of the atmosphere (particularly troposphere) using Global Navigation Satellite Systems (GNSS) to deliver information about its state. The two currently available navigation satellite systems are the Global Positioning System (GPS) and the GLObal'naya NAvigatsionnaya Sputnikovaya Sistema (GLONASS) maintained by the United States and Russia, respectively. The Galileo navigation satellite system, which is under supervision of the European Space Agency (ESA), is expected to be completed within the time frame of a few years. Continuous observations from GNSS receivers provide an excellent tool for studying the earth’s atmosphere. The GNSS meteorology has reached a point, where there is a need to improve methods not only to compute Integrated Water Vapor over the GNSS receiver, but also to investigate the water vapor distribution in space and time (4DWVD). Since 2008, the new national permanent GNSS network ASG-EUPOS (98 stations) has been established in Poland. 17 Polish stations equipped with GNSS receivers and uniform meteorological sensors work currently in the frame of the European Permanent Network. This paper presents the concept of the integrated investigations for NRT atmosphere model construction based on the GNSS and meteorological observations from ASG-EUPOS stations., Jarosław Bosy, Witold Rohm and Jan Sierny., and Obsahuje bibliografii
The mountain type of climate, which is typical for the Sudety Mountains, is well known for its rapid and frequent changes in pressure, temperature and humidity. The fluctuations in meteorological parameters cause fast changes of the tropospheric delay, as a correlated value, and in consequence difficulties in GPS heights determination. The tropospheric delay is a function of the meteorological parameters obtained directly from synoptic stations and models. The paper presents the procedure of tropospheric delay estimation on the European Permanent Network and International GNSS Service (EPN/IGS) stations, using meteorological observations from synoptic stations (Wrocław Airport, Śnieżka) of the Polish Meteorology Service (IMGW), stations (Cervena, Praha-Kbely) of the Czech Hydrometeorological Institute (CHMU), and sensors mounted close to the antennas of the permanent GNSS stations (BISK, SNEC, WROC, GOPE). The values obtained from Global Pressure and Temperature (GPT) model were bases for the meteorological data calibration at EPN/IGS stations. The tropospheric delay (Zenith Total Delay - ZTD) on EPN/IGS stations was obtained from Saastamoinen formula and compared with ZTD from EPN solutions., Witold Rohm and Jarosław Bosy., and Obsahuje bibliografické odkazy
The future of the global and local geodynamic researches belongs to permanent monitoring. The conception of the semipermanent GPS observations’ application in geodynamic research in Sudetes area is presented in this paper. The conception is based on spatial modeling of the disturbing phenomena in the coordinate time series of (semi) permanent stations. The local interplate movements and their correlation with major European tectonic structures are determined on the strength of coordinate time series of these stations. The problem of epoch integration with semipermanent and permanent (EPN/IGS) observations for local geodynamic monitoring is also investigated., Bernard Kontny, Jarosław Bosy and Andrzej Borkowski., and Obsahuje bibliografii
