Thematical map creation in locality V zrcadlech - northern part
Matušková, Klára ; Jurčík, Josef (referee) ; Kratochvíl, Radim (advisor)
The purpose of this bachelor´s thesis was a tacheometric measuring of a historical mining site in the Olomučany cadastre. A survey net was built in the area, using the GNSS technology and a traverse oriented on both ends. Detailed points have been determined by tacheometry. The result of the thesis is a large scale thematical map made in the CAD system with the emphasis on hypsography. The map should be used as a comparison to the historical mining map.

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.

Determination of accuracy´s characteristics of some GNSS and evaluation of their utilization for the recording changes in land use.
KLINGR, Michal
This diploma thesis deals with a comparison of the measured data using various GNSS apparatures. In the theoretical part, the general structure of navigation systems is described and the comprehensive overview of navigation systems in the world is elaborated here. The next chapters are devoted to regional and augmentation navigation systems. The last chapter in the theoretical part is focused on point field in the Czech Republic.In the practical part of this thesis, the experimental measurement using various GNSS apparatuses was carried out in cadastre unit Kokořov. Subsequently, the measured data were transformed into S-JTSK and compared with each other. In the end, using various GNSS for the purpose of registration changes in landuse was evaluated.

Revision and completion a courseware geodetic field "Lipno"
MATOUŠOVÁ, Martina
This diploma thesis focuses on introduction of nowadays quite common technology - GNSS (global navigation satelite systems). In its part, it revises and completes a courseware geodetic field Lipno, which has been established for the needs of geodetic operations courses for students of University of South Bohemia in České Budějovice, landscape management.

Design, build and do a geodetic survey of network of triangulation, as a geodetic base for topographic and altimery measurements in surveying locality
ČTVRTNÍK, Vladimír
The project proceed in the context of future projects in the examined locality. The main aim of this work is to design, build and do a geodetic survey of network of triangulation, and also secure geodetic base for the future topographic and altimery measurements. The project is comprised of the theoretical and practical technical process of obtaining results by terestrial and GNSS methods. The project is also focused on the comparison of these methods. All needed materials for the following measurements was secured by the surveying work, and of the required quality. The final product of this project is the complete network of triangulation, which fulfil the requirements of the subsequent geodetic measurements in the examined locality.

Implementation of geodetic works within stakeout of landscaping
KLEMPA, Petr
Bachelor thesis "Implementation of geodetic works within stakeout of landscaping" is focused on the description of the process of geodetic methods and their subsequent implementation in the terrain, specifically in the area of Vitín. Stakeout took place on the basis of a valid digital cadastral maps. There was staked out eight points by polar method on the border of the parcel 1130/8 in cadastral area Vitín. There was staked out eighteen points by GNSS method on the border of the parcels 810/5 and 760/11. The aim of the study is to compare and evaluate of used geodetic methods in terms of accuracy, time constraints, etc.

Porovnání přesnosti hybridní GPS + GLONASS a běžné GPS aparatury v podmínkách lesních porostů
Klváček, Ladislav
The work presents a comparison of the accuracy and reliability of collecting geospatial data by hybrid and conventional GPS apparatus in terms of selected forest locations at the SLP ML Krtiny. For this comparison, the chosen standard equipment was the Trimble GPS Pathfinder ProXH which processes signals only from the global satellite navigation system NAVSTAR GPS and the hybrid receiver Pathfinder ProXRT receiver, which is able to receive GPS signals and the signals of the global navigation satellite system GLONASS. For this purpose, a self-testing kit was designed consisting of a Trimble Tornado dual-frequency antenna, which was the connected to the GNSS receivers via a signal splitter unit. The advantage of this system is that both GNSS devices receive signals from a common antenna, ensuring that observational conditions are completely identical. Data collection was carried out at three sites with different terrain and forest conditions and on the spot with the best observational conditions (roof LDF). Observations were made for a period of one hour at each location. The processed results revealed that the GLONASS system used in conjunction with the GPS system delivered less accurate results than expected. In only one instance did the hybrid system deliver accurate data; this was when observational conditions were particularly poor, due to forest conditions and terrain. In this case the GLONASS plus GPS system benefited from a continuous satellite signal, whereas the GPS system suffered from only intermittent satellite contact. After the application of post-processing correction through the virtual reference station network CZPOS the margin of error was generally reduced, resulting in a lower RMS for both receivers, but the higher number of satellite contacts with the hybrid system resulted in more accurate results only under especially poor environmental conditions.
