Accuracy testing of minor horizontal geodetic control determined by analytical aerotriangulation
Komárek, Josef ; Weigel, Josef (referee) ; Kratochvíl, Radim (advisor)
The purpose of this bachelor’s thesis is testing quality of minor horizontal geodetic control points in chosen area in South Bohemia. The control points have been established in the eighties of twentieth century during cadastrial mapping (large scale base map). Until now, those points were recorded in the 4th accuracy class. The geodetic control was remeasured with RTK technique, then deviations were calculated. These results were reviewed and evaluated whether the points match with the 4th accuracy class or even the 3rd accuracy class. The results were submitted to the local cadastral office in Jindřichův Hradec.

Documentation of Balkónová and Balkóta passages in Býčí skála cave
Velecká, Kateřina ; Kuruc, Michal (referee) ; Kratochvíl, Radim (advisor)
The bachelor thesis deals with documentation of the part of cave system Býčí skála, namely of the passages Balkónová chodba, Balkóta and part of the passage Kóta 314 in the form of a ground plan, extended longitudinal section and cross sections in the scale of 1:250. The thesis contains a short description of the locality, steps from recognition and completion of the existing measuring network to a detailed survey and creating of the final map in the JTSK coordinate system and the Bpv height system. For the detailed measurement was used a special speleological measuring method utilizing a device DistoX2 with a tablet and the program TopoDroid for creation of the measuring sketch.

Testing of Precise Point Positioning Method
Nosek, Jakub ; Kratochvíl, Radim (referee) ; Machotka, Radovan (advisor)
This diploma thesis deals with the Precise Point Positioning (PPP) method in various variants. The thesis describes the theoretical foundations of the PPP method and the most important systematic errors that affect accuracy. The accuracy of the PPP method was evaluated using data from the permanent GNSS station CADM, which is part of the AdMaS research center. Data of the period 2018 – 2019 were processed. The results of combinations of different GNSS and the results of different observation periods were compared. Finally, the accuracy was verified at 299 IGS GNSS stations.

Development and testing of device for absolute GNSS antenna calibration
Komárek, Josef ; Machotka, Radovan (referee) ; Kratochvíl, Radim (advisor)
The purpose of this diploma thesis is testing motion of the device for GNSS antenna calibration according to added weight to the device’s transom. First part of this thesis is devoted to introduction into GNSS antenna calibration problematics. The thesis deals further with development of the software used to process photogrammetric images that have been taken during testing measurement. The rest of the thesis is focused to process and evaluate the measurement. The result will be implemented into observation model used during calibration measurement. The period, during the device is still, will be corrected according to the result that has been obtained from the measurement.

Creation of software support to device for absolute GNSS antenna calibration
Galata, Marek ; Kuruc, Michal (referee) ; Kratochvíl, Radim (advisor)
The diploma thesis deals with creation of software support for the robotic device used for absolute GNSS antenna calibration, which is developed by Institute of Geodesy at Faculty of Civil Engineering, Brno University of Technology. In the beginning of this thesis, there is in general discussed issue of absolute GNSS antenna calibration. Then the text continues by description of calibration device itself together with summary of testing performed so far. Next sections are focused on its main content. There is mentioned testing calibration process, followed by all of every single steps, which leads the procedure towards gaining calibration parameters for removing errors arising due to instability of antenna´s phase center position.

Documentation of the church in Čučice village
Súkeníková, Terézia ; Machotka, Radovan (referee) ; Kratochvíl, Radim (advisor)
The aim of this thesis is the documentation of the church of James the Greater in the South Moravian village Čučice. It is complete drawings of the structure, consisting of the topographic situation around the church, floor plans, vertical sections and views on the facade. Text part contents writing about working activities. It also discusses the historical and cultural characteristics of the church as immovable monument, the description of the preparatory work, a way of building surveying networks and methods of measurement. Finally, it highlights the processing of measured values in the computing and graphics phases. Use of this thesis and its evaluation is given in the final chapter. Graphic documentation, along with sketches, notebooks, calculation protocols, lists of coordinates, and testing the accuracy are in the annex section.

Documentation of Skalní zámek passage in Býčí skála cave - southern part
Kubíčková, Alena ; Hanzl, Vlastimil (referee) ; Kratochvíl, Radim (advisor)
This bachelor thesis deals with speleological mapping of a part of the cave system Býčí skála in the Moravian Karst. The part that has been mapped is called Skalní zámek. For the purpose of this work documentation was processed for the southern part of the Skalní zámek. The existing graphic materials of the interest site were searched for and described. For processing purposes, available numerical data were also found, which were compared with the new measurement during processing. The polygon of Skalní zámek was measured by mining suspension compasses. For detailed measurements, a combination of the modified DistoX2 - laser distance range-finder and TopoDroid - software application per the appropriate tablet, was used. The results of the measurements were processed in an a free and open-source cave surveying software - Therion. In this program a ground plan of the Skalní zámek, a longitudinal section of the main hallway and a longitudinal section of the branching hallway was prepared. At the end of this work the symbol lists used by TopoDroid and Therion were compared with the official UIS symbol list
