Evolution of the air navigation services in the European open sky concept
Sahrai, Daniel ; Šplíchal, Miroslav (referee) ; Vosecký, Slavomír (advisor)
This bachelor thesis deals with technologies and methods provided by air navigation services. This work aimed to create a cross-section of the history of the development of such technologies and methods and to present new and developed technologies and methods designed for European airspace. The result is an overview that serves as study material for understanding the problems of insufficient airspace capacity and for understanding the directions taken by the EUROCONTROL.

Navigation Systems
Pospíšil, Václav ; Dobrovský, Ladislav (referee) ; Šeda, Miloš (advisor)
The first part of the thesis is devoted to a comprehensive description and development of global navigation satellite systems, which is followed by the second part, which adresses their use through navigation devices and applications. The second part discusses the properties and specifications of individual devices and applications. Part of this work is the final evaluation of individual applications in terms of their technical parametres.

The concept of security dilemma in the environment of outer space: the case of the Galileo system
Němečková, Marie ; Doboš, Bohumil (advisor) ; Špelda, Petr (referee)
This diploma thesis applies the well-established concept of security dilemma to the relatively new domain of outer space. It constructs a comprehensive modification of the concept for the outer space - the space security dilemma - and establishes criteria for the assessment of it while also discussing previous approaches. The thesis then applies this concept and established criteria, to the issue of Global Navigation Satellite Systems (GNSS). More specifically, it focuses on the case of the European GNSS called Galileo and assesses the intentions behind its creation. Through this assessment, the thesis focuses on determining whether the European Union became a space security dilemma initiator by the development of the Galileo system. In order to confront the theoretical conclusions with praxis, the thesis then focuses on the case of the United States of America and the confrontation between GPS and Galileo. In its last chapter, the thesis replicates this approach on the cases of the Russian Federation (and its GLONASS) and the People's Republic of China (and its BeiDou/COMPASS).

Use of GPS in the Car Industry Oriented on Self-driving Vehicles
Gróf, Marko ; Sedláček, Pavel (referee) ; Šedrlová, Magdalena (advisor)
Tato bakalářská práce se zabývá využitím GPS v automobilovém průmyslu se zaměřením na bezpilotní vozidla. Hlavním cílem bylo přiblížit GPS systém jako takový, jeho využití v autonomních vozidlech, vysvětlit výhody i nevýhody těchto automobilů a popsat různé hardwary a softwary, které dále využívají. První polovina práce nejprve do velkých detailů charakterizuje GPS, aby se čtenář seznámil s tím, jak navigační systém pracuje. V druhé části se čtenář dozví o autonomních vozech, do jakých úrovní jsou rozdělena, a které systémy používají. Dále jsou zde popsány výhody a nevýhody těchto vozidel a také hlavní rozdíly mezi dnešními a autonomními auty. Závěr této práce je soustředěn na benefity inteligentní dopravy, ale i na pohled do budoucnosti vozidel či celé dopravy.

Software GNSS receiver
Jedlička, Petr ; Bobula, Marek (referee) ; Záplata, Filip (advisor)
The thesis deals with the analysis and the reception of the freely available signals of the navigation satellites in the L1 and E1 bands of the GPS and Galileo systems. The described signal reception sections include the process of the acquisition, the carrier frequency and phase synchronization and tracking, the spreading code phase tracking, the signal demodulation and the channel decoding. The simulation of the entire receiver is performed in MATLAB. The deeply analyzed signal reception component is the one responsible for the carrier phase and frequency synchronization and tracking. In that case, more methods and their comparison are usually listed. The signal reception component, which is responsible for the carrier phase and frequency tracking and the spreading code phase tracking, is also implemented in FPGA.

Car Localization Using Satellite Systems
Uhliar, Martin ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
This bachelor thesis deals with the design, hardware and software implementation of a location device which can get a location data and speed of a car on the Earth's surface. Through the GPRS mobile network, the obtained values are transferred to a remote server and then stored in a database. This data is presented to the user via a web application that displays the current location of the car on the map. The device is controlled by ARM microcontroller.

Multipurpose bicycle alarm
Albert, Matej ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This diploma project is about designing a concept of an anti-theft tracking device for a bicycle. The device is equipped with a GNSS module for tracking of current location, GSM module for sending the location data in case of a theft and a BT module for user settings via mobile phone. The bike theft detection is detected by an accelerometer. The final goal of this project is a concept of such a device for evaluation and improvement purposes.

Antenna a LNA for multiband GNSS receiver
Ondráš, Michal ; Baran, Ondřej (referee) ; Záplata, Filip (advisor)
This project describesa microwave antenna for GNSS and low noise amplifier. Mikrostrip antenna is a modern type of antenna. This mikrostrip antenna is Dual – band antenna with circual polarization. The thesis describes how to make anantenna, what a circular polarization is, whata patch antenna is and what GNSS is. Low noise amplifier amplifies the antenna output signal.

Determining of Dron Localization Using Navigation Systems
Nosál, Jan ; Goldmann, Tomáš (referee) ; Drahanský, Martin (advisor)
The thesis describes problems of drone navigation using navigation systems with which the navigation modules that have been tested are able to work. Next the issue with flight path and the determination of the incline and direction of the flight of the drones was solved also. Drones are more and more popular devices used for military, agricultural and commercial purposes. The thesis contains information about most used navigation systems which we encounter every day especially in cars and aircrafts. There were tested two navigation modules for drone localization. Modules capable of handling five navigation systems GPS, Glonass, Galileo, Beidou, QZSS and they can communicate with the Arduino board and IMU controller for drone positioning.
