System for Identifying Above Ground Level of Flying Objects
Boba, Peter ; Mičulka, Lukáš (referee) ; Strnadel, Josef (advisor)
This master's thesis deals with design and development of a system for measuring altitude (height above ground level) of flying objects. It describes theoretical background related to altitude measurements in avionics as well as various techniques of altitude measuring. The measurement is conducted by HMD (Height measuring device) - embedded system which uses barometric pressure sensor to measure altitude. The main part of this thesis is dedicated to ground unit - a server running custom set of applications. Using this server and radio link, it is possible to send control commands to HMD, receive data, and propagate data into web application. Furthermore server acts as a data storage and is able to process and analyse data. The thesis also discusses the precision of the measurement and the data output. System was tested and used during several glider aerobatics competitions.

Aerospace - Futuristic Aircraft Cockpit Design
Bílek, Jan ; Bartoň, Radek (referee) ; Chudý, Peter (advisor)
This work describes the visualization design of the flight related quantities in a cockpit of a modern light sport aircraft. It focuses on the utilization of the state of the art trends in flight data displays and introduces the innovative implementation of the aircraft's energy state smart clues that reduce pilots' workload. The initial part of the work presents a research into the flight, engine and navigation data presentation on analog instruments, followed by their illustrative depiction in glass cockpits. Within the framework of this thesis, Microsoft Flight Simulator has been used as a source of the flight related data. Final advances in the display design were introduced through the implementation of the synthetic vision system and a visualization of the virtual tunnel in the sky.

Radar Altimeter for Ultralight Aircraft
Absolon, Marek ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
The main topic of this paper is a radar ranging for use in an aircraft altitude measurement. This should help beginner pilots in practicing landing and take off. To achieve this aim, we chose to use continuous-wave radars with frequency modulation (FMCW). Our solution is based on linear frequency modulation method using triangular modulation pattern. During the testing, it was found out, that radars with 24 GHz bandwidth have a range resolution from 1 meter (depending on modulation depth) to 13 metres. This range is sufficient for usage in training of takeoffs and landings, which is the real purpose of this paper. Another good finding is, that during takeoff and landing, there is minimal occurrence of doppler frequencies. Final algorithm works on principle of two currently processed spectrums, which are substracted. Afterwards, found peaks are validated on current spectrum.

Cyklocomputer with Altimeter
Čech, Tomáš ; Slanina, Martin (referee) ; Hermany, Jiří (advisor)
The target of the project is to get acquainted with parameters of magnetic sensors for impulse measurements and of atmospheric pressure sensors. Furthermore there is necessary to choose a proper microcontroller and LCD for measured values displaying. The equipment for bicycling will be projected and constructed afterwards. It will allow to display information on moved distance and also on its superelevation. All data will be stored in the memory. The project also includes microcontroller-PC communication by USB and data transmission from the memory.

Digital signal of pressure senzors processing using CPLD
Zátura, Michal ; Fedra, Zbyněk (referee) ; Kováč, Michal (advisor)
The goal of this bachelor’s thesis is to design electronic part of the scanning system used to measure altitude. The electronic part is designed as module connected to the development platform XC2-XL. This module is realized like PCB. The principles of the signal processing of the signal from the pressure sensor MPXH6250, particular blocks of the designed module and principle of the barometrical altitude measuring are also described in this thesis. Thesis briefly informs about designing environment Xilinx ISE, VHDL language, the principle and the application of the pressure sensors, the structure of the programmable logic device CPLD and FPGA, the development platforms XC2-XL, the Xilinx Spartan-3 Starter Kit, the programmable logic devices CPLD Coolrunner-II XC2C256 and Spartan-3 XC3S200 FPGA used on the development platforms. The very important part is to design algorithm for processing the logarithm in the digital logic and it´s implementation in VHDL language.

Optic flow software module design
Grulich, Jan ; Růžička, Michal (referee) ; Věchet, Stanislav (advisor)
This bachelor thesis is focused on the analysis of optical flow. The first part is dedicated to the theoretical analysis of the motion of image features. Especially important is finding quality features that can be tracked in a videosequence. Detailed mathematical description of the necessary algorithms is presented. The second part describes the software and its functions with the implemented algorithms. The main function is determining the distance of an object from the camera based on its velocity. Empirical tests of this function are presented.
