Aspects of GNSS Processing
Puchrik, Lukáš ; Kostelecký,, Jan (referee) ; Kratochvíl,, Vlastimil (referee) ; Hefty,, Ján (referee) ; Švábenský, Otakar (advisor)
The thesis deals with processing of epoch-wise GNSS measurements from local geodynamic network Sněžník. Its aim is to evaluate the geodynamics in the area of Králický Sněžník Massif and to assess the capabilities of epoch-wise GNSS measurements to detect the geodynamic movements. Within the thesis the comprehensive processing of all the GNSS measurements observed between years 1997 and 2011 is realized using the reprocessed products of first IGS reprocessing Repro1. Bernese GPS software version 5.0 is used for all the processing.

Deformation Measurement of the Roof Structure of a Sport Hall
Klinčík, Radoslav ; Švábenský, Otakar (referee) ; Bureš, Jiří (advisor)
Diploma thesis describes the measurement and evaluation of displacements and deformations of the wooden roof structure of the aquapark hall in Brno – Kohoutovice. Part of the work is devoted to the preparation and testing of used devices and tools. The main part of the work consists of performing one stage of measurement using the polar method and the laser scanning method. The polar method measurement is compared with the results of the polar method of the previous stage. The next part of the work deals with the comparison of the polar method and the laser scanning method measured in the last stage. The results achieved are interpreted in the final part of the work.

Deformation Surveying of Bridge Construction and Railway Track
Staněk, Boleslav ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
This diploma thesis deals with the phases measuring deformation of the bridge construction and railway superstructure on the bridge over the river Dyje in Breclav and its surroundings. The main goal was to determine the longitudinal displacements of the rail web and the bridge structure. The object of this thesis was also transverse displacements which have been caused mainly due to temperature changes. The introduction describes the location. The following section discusses the methodology terrestrial deformation measurements and calibrations selected surveying devices. Furthermore, there is stated the processing of measurements and the calculations. In conclusion, the thesis evaluates the longitudinal and transverse displacements, which are shown in the annexes.

Deformation Surveying of Railway Track
Suchánek, Zbyněk ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
The aim of this master thesis was to measure and evaluate shifts of rail strip and deck of the bridge in the 0,206 km route Zábřeh - Bludov across the river Moravská Sázava. The measurement was performed by classical geodetic methods. The result of the study was evaluation of the three periods of deformation measurements and numerical and graphical documentation. Shifts were caused especially by changes in temperature and operational effects.

Deformation Surveying of Bridge Abutment and Top of Earth Fill
Malota, Matěj ; Kuruc, Michal (referee) ; Švábenský, Otakar (advisor)
The subject of my bachelor´s thesis is shift observation of abutment and the top of earth fill at western side of the Ivančice viaduct. It is unstable due to complicatedhydro-geological conditions while merging the abutment and the adjacent, 23 metres high slope of embankment.In my thesisI am processing previous periods of GPS monitoring, which were measured since spring 2000 to autumn 2009, and also two of my own measured periods at spring 2012 and 2013.

GNSS Deformation Measurement of Railway Structure
Buday, Michal ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
The purpose of this thesis is to evaluate the train bridge shift using the satellite geodesy methods. Introductory part of the thesis is devoted to GNSS basis. The following part discribe work with commercial software Leica Geo Office. Results of calculations were transformed to local topocentric frame. In this frame were compared differencies between GNSS meassurment and classical terrestrial methods. Part of this thesis is to consider tropospheric refraction influence based on used tropospheric model. The end of this thesis is devoted to consider hypothesis that reference point which was considered as solid does not show trend of changing it's location. For this purpuse BERNESE GPS Software was used. GNSS meassurments were linked to the nearest points of permanent GNSS networks. Results are documented numerically and graphically.

Map of the Dratenická Cave Surroundings in Moravian Karst
Hanuš, Vojtěch ; Švábenský, Otakar (referee) ; Weigel, Josef (advisor)
The aims of my diploma thesis are the design of a map of Drátenická cave surroundings in the Moravian Karst in the 1:500 scale with details utilizable by speleologists and the examination of a map of 1945 depicting the region of Drátenická cave. The thesis includes an elaboration of the theoretical foundations relevant for the fulfillment of the aims and the descriptions of the geodetic and processing procedures. The outcome of the thesis is the planimetric and altimetric survey, a new digital map of the region and the final examination of planimetric and altimetric components of the map of 1945.

GPS measurements at the Tetčice polygon
Darmopilová, Jana ; Švábenský, Otakar (referee) ; Pospíšil, Lubomil (advisor)
This thesis deals with periodical measurements at the Tetčice polygon to confirm geological activity caused by geological shift that pass through the center of the village. This work was focused on the third phase of measurement by long static GNSS observation in summer 2013 to monitor horizontal shifts on both edges of Boskovice furrow. Points are stabilized on pillars with forced centring. Part of the thesis is summary of present results, the differences between the various stages and graphical representations of shifts. The theoretical part deals with the geological conditions in the area and description of GNSS technology.

Deformation Surveying of Railway Track
Štrba, Peter ; Weigel, Josef (referee) ; Švábenský, Otakar (advisor)
The aim of this diploma thesis is to specify the displacement and deformations of the railway tracks axis on bridge structures in cities of Zábřeh na Moravě and Břeclav. The bridge structures covered have great dilatation distances, therefore it is necessary to monitor the movements of the railway tracks depending on climatic conditions. GPS methods have been used throughout the whole measurement and data processing. The result includes also a comparison of GPS and conventional methods. The result of the thesis is a detection of proven displacements. One of the goals of the thesis is the comparison of the displacements and the accuracy using the method chosen by author of the thesis and using classical geodetic methods.
