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.

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.
