Testing of astronomical positioning system MAAS-1
Kremser, Christian ; Vondrák, Jiří (referee) ; Machotka, Radovan (advisor)
This thesis deals with testing of astronomical measurement system MAAS-1, which was developed at the Institute of Geodesy, Faculty of Civil Engineering, Brno University of Technology. Several reference measurements were done on the terrace of B building Faculty of Civil Engineering during this testing. The data obtained were processed into astronomical geographic coordinates and . These coordinates, as well as atmospheric conditions and calibration measurements, are basis for evaluation. In this test I try to detect the influence of the CCD sensor mounting of the accuracy on the final data and to assess if the construction needs to be modified.

Geodetic syrvey of velodrom in Prostějov
Řezníčková, Dagmar ; Kuruc, Michal (referee) ; Machotka, Radovan (advisor)
The main object of bachelor thesis is geodetic survey racetrack real status of the velodrome in Prostějov, determination of its length and as well as identification of specific elements. In the introductory part of the thesis there are information’s about location and the description of used measurement methods. Next parts deals with own surveying of the velodrome and with others important elements in the track area. GNSS technology was used for building the network of auxiliary measuring points. After that, with tachymetrically method the detailed points were measured. In the last part a processing of measured data is described. The result of this thesis is a planar plan in scale 1:250.

Application of robotic total station for crane tracks measurement
Chomjak, Ján ; Foral, Jakub (referee) ; Machotka, Radovan (advisor)
This diploma thesis deals with application of robotic total station for crane tracks measuring. To determinate straight of rail tracks was used system of automatic target recognition. One crane track was measured by two methods. Horizontal deviation from straight direction was determinated directly by the method “line of sight” and indirectly using measuring angles and lengths. To determinate height continuance was used engineering and trigonometric leveling. The results of measuring proved, that reached deviations between methods are minimal, so we consider them as equal. System system of automatic target recognition reliably and with sufficient accuracy aims to the prism-centre.

Application of 3D Industry Surveying during the Manufacturing of Structures for Subsea Oil and Gas Production
Baier, David ; Kalvoda,, Petr (referee) ; Machotka, Radovan (advisor)
The thesis suppose to introduce the dimenisonal control surveyor’s role during manufacturing of the oil subsea structures, which are utilized for subsea pipeline systems assembly. The thesis contain the theory of oil production from the seabed, resources utilized for those purposes and describe the manufacturing process of the subsea equipment. The main focus of the work is in describing the methods (more detailed) applied during dimensional control, along with method of surveying, calculations and result presentations. The essential part is showing data processing of one representative structure, which the author processed himself during his particiaption on the project.

Accuracy Analysis of Astronomical Positioning Results
Jalovecký, Martin ; Kratochvíl,, Radim (referee) ; Machotka, Radovan (advisor)
This diploma thesis is focused on the analysis of results accuracy of astronomical positioning. It describes observation methods and the latest surveying systems used in geodetic astronomy. Further in the thesis there is the description of surveying system MAAS-1. Subject of the elaboration is the data obtained by measuring with this system. Testing is focused on digital camera. There is also an analysis of the results of geographical coordinates, depending on the accuracy of determining the angled pixel size and also on the accuracy of the input coordinates.

Documentation of Barová cave - central part
Chaloupka, Roman ; Machotka, Radovan (referee) ; Kratochvíl, Radim (advisor)
The aim of this bachelor thesis is the graphic documentation of Barová cave – central part in the form of a plan and transection in a scale of 1:250. The thesis contains, including brief description of the area, all steps from reconnaisasance and completion of the existing measuring network to the measuring and processing part leading to the creation of the resulting map.

Geodetic Survey of the Rear Palace of the Veveří Castle
Gabrlík, Marek ; Foral, Jakub (referee) ; Machotka, Radovan (advisor)
The purpose of my diploma thesis is geodetic survey and creation of the drawing documentation of the first two above-ground floors of the rear palace, four above-ground floors of the adjacent prismatic tower and the facades of the two assigned objects accessible from the courtyard. The geodetic survey was made in connection with the previous measurements of the neighboring English tract by the combination of the polar and the standard measures. The calculation of the obtained data was done in Groma and the required drawings were made in Microstation. The result of my thesis is the drawing documentation consists of four plans, longitudinal section, cross section and two views.

Quasigeoid profile Velká Bíteš - Uherské Hradiště
Kratochvíl, Richard ; Kratochvíl, Radim (referee) ; Machotka, Radovan (advisor)
This thesis deals with use of astronomical-geodetic and gravimetric leveling to calculate quasigeoid profile. The main input data in the calculation are gravimetric vertical deviations on point of profile. The aim of this thesis is the processing and calculating of the profile of relativ quasigeoid with three different methods and then comparing the calculation results with gravimetric quasigeoid and GPS/leveling.

Station testing of Mobile automated astronomical system
Sasyn, Jan ; Kuruc, Michal (referee) ; Machotka, Radovan (advisor)
Subject of this master´s thesis is a station testing of Mobile automated astronomical system No. 1 (MAAS – 1). This system is used for measurement of astronomical coordinates by measurments of the stars. This thesis is focused on impact of some systematic effects, especially effects of inaccurate input geographic coordinates to resulting coordinates.
