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.

Metody navádění mechanizačních prostředků po pozemku při provádění pěstebních zásahů
Novotný, Vojtěch
Bachelor thesis entitled "Methods for guidance mechanization on land in the implementation of silvicultural interventions" aims to describe GNSS systems, the principle of their function and distribution. The first section describes the functions of GNSS and its products and related systems that are involved in signal transduction. The next section is technical settings menu and set the method for the movement of the land. The next section describes growing operations spreading fertilizer, chemical treatment of crops and crop establishment methods for using GPS. The last section shows the possible future development of satellite navigation technology in agriculture.

Use of GNSS apparatus for designing and documenting mountain bike (MTB)
ŠLECHTOVÁ, Štěpánka
The theme of this work is the use of GNSS apparatus for designing and documenting mountain bike (MTB). Its aim is to propose a new bicycle paths in the Ore Mountains using GNSS equipment. The individual measurements they then process documentation, including directional waves and longitudinal sections of routes. The documentation also includes locating and gathering information on significant points along the route. The result of the work are descriptions of routes and their waveforms generated directional and longitudinal profiles that are processed in digital form with the possibility of their further use. In one of the proposed routes were compared directly measured longitudinal profile with a profile designed by The maps of the Czech Republic 1:25 000

The use of GNSS technology for the purpose of demarcation land consolidation
JUSTOVÁ, Lenka
The goal of the submitted thesis was setting out newly proposed borders of land with GNSS technology in the context of the land consolidation. For a locality was selected cadastral area Kamenný Újezd near the České Budějovice. The procedure of each activity was related to the demarcation of the total of 78 points with GNSS method. The thesis revealed a time demands and a lower accuracy and while showed reduced effectiveness of using. The accuracy was related to the mean value coordinate error. The comparison was carried out with the geodetic method. At the same time to be solved a question of usefulness and meaningfulness stake out work for the purpose of land consolidation and the relationship of new owners to the new borders of land.
