Use of Astronomical Levelling for Creation of Quasigeoid Models
Jurčík, Josef ; Weigel,, Josef (referee) ; Machotka, Radovan (advisor)
My master´s thesis deals with use of astronomical levelling for creation of quasigeoid models. The basic input dates are componets of astronomical-geodetic deflections of the vertical in points, which are determined on AGNES and VEVEŘÍ nets. The dates are adjust for determination of relative quasigeoid. In literature [4], there is simplified solution for adjustment of this dates. The thesis looks for the most comprehensive solutions of adjustment without simplification. The solutions are compared.

Horizontal and vertical positioning of field training survey nets
Suchánková, Tereza ; Volařík, Tomáš (referee) ; Machotka, Radovan (advisor)
The subject of this bachelor thesis was a positional and height determination of the points of educational measuring networks in selected localities in the cadastral area of Veveří. The work describes the process of measuring and office work. It desribes a stabilization of the points of the measuring network, the connection to the S-JTSK reference system and the Bpv height system, the list of coordinates and heights and the graphic documentation of the measuring networks.

Stage Measurement of shifts using Leica Sprinter 150 M
Kubištová, Pavlína ; Machotka, Radovan (referee) ; Vondrák, Jiří (advisor)
The aim of this Bachelor thesis is to assess whether it is possible to use the Leica Sprinter 150 m leveling device, with its precision moves on the edge of technical and precise levelling, for the purposes of precision levelling. By entering a Bachelor's thesis was focused in three stages, the object in Černého street No. 15, 17, 19, in Brno Bystrc, which is observed due to the inclination of the object in the direction of the Valley and to compare the measured value with the values given. On the basis of measurements to assess whether it is possible to the Leica Sprinter 150 m leveling device to use for the exact level indicator.

Surveying an area of St. Simon and Juda´s church in Radostice
Nevěřilová, Eliška ; Machotka, Radovan (referee) ; Foral, Jakub (advisor)
The aim of this bachelor thesis is surveying an area of St. Simon and Juda´s church in Radostice and nearby surroundings and after-processing for need of National Heritage Institute. The first part of the thesis is concerned in surevying and the second part of the thesis describes procesing those data and creating a thematical map with contour lines, views on the building from all sides and sectional views.

Geometrical parameters of device for absolute GNSS antenna calibration
Brátová, Kateřina ; Machotka, Radovan (referee) ; Kratochvíl, Radim (advisor)
The aim of this work is description of a device developed at Brno University of Technology, Faculty of Civil Engineering, Institute of Geodesy for the purpose of absolute calibration of geodetic GNSS antennas. Thanks to calibration it is possible to remove systematic error of antenna's phase centre. The device consists of moveable arm and processing unit. The moveable arm is able to set up calibrated antenna to required azimuth and elevation angle. This work introduces the issue of absolute calibration, describes the moveable arm and the process of its assembling. Further, it defines geometrical parameters of moveable arm, describes their determination and their independent verification by geodetic method. Finally, the model of movement of antenna's reference point is described.
