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.

Development localization board
Szabó, Michal ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This document describes a device capable to determine geographical position thanks to its GNSS module and measure the change of movement with the help of an accelerometer and gyroscope. Outputs of these integrated circuits are combined, data are processed and fused thanks to a numerical integration and mathematical filters. Results are stored on a memory card. The whole development is described from a concept, through the making of the device and software algorithms to the testing of its functions.

Satellite navigation system GLONASS 2018+ (student handbook)
Navrátilová, Karolína ; Hlinka, Jiří (referee) ; Vosecký, Slavomír (advisor)
The aim of presented bachelor thesis is produce study aid on the topic global satellite navigation systém GLONASS 2018+. The work deals with the development of the system itself and signals, navigation messages and individual system segments, that makes up the system as a whole. The work also includes an overview of current development and direction of future development, as well as overview of navigation metods where the services of the GNSS are used. Part of the work is devoted the developing european´s sattelite system Galileo and american system GPS. The last chapter deals with four important criteria, i.e. availability, integrity, continuity and accuracy where the systems of GNSS are compared.

Algorithms for calculating the position, velocity and time from GNSS signals
Kučera, Tomáš ; Kovář, Pavel (referee) ; Tejmlová, Lenka (advisor)
This master thesis describes the principles of the Global Navigation Satellite System GNSS, specifically the GPS, GLONASS and Galileo systems. The thesis analyzes the structure of individual GNSS subsystems and introduces their properties. The algorithm for calculating the position is designed in the interactive programming environment MATLAB for the processing of GPS and GLONASS sampled signals. The position is calculated by a distance measurement method which searches for the intersection of spherical surfaces. The calculation is designed for four satellites and when more satellites are detected, the calculation is repeated for all possible combinations. From this position the combination with the lowest DOP (Dilution of Precision) factor is determined, and the calculation of the position is repeated for the best constellation of satellites. In this thesis the user graphical interface for entering the input of data, input parameters and the display of calculated values are created. Finally the calculation of the measured data is displayed on the selected location online map portal

Navigation systems
Jirkovská, Šárka ; Stejskal, Vojtěch (referee) ; Pust, Radim (advisor)
This bachelor´s thesis is focused on the navigation systems GPS, Galileo and their development. The work describes the functions and parameters of mentioned navigation systems including individual modulation techniques, used frequencies and signal securing by encoding. Segments of navigation systems GPS and Galileo, which divide into control and space parts, are mentioned next. The principle of signals generation by GPS system satellites, where the navigation message is the basis of user´s data transfer, is introduced. The principle of generation of the navigation message is described as well as its structure and characteristics of used CA-code and P-code. Next part of the work presents the components of the Galileo navigation system satellites and conspectus of planned services of this system. The summary of used receivers’ characteristics and summary of selected producers of digital geographical data for navigation devices follow next. The last part mentions the simulation of signal generation of GPS satellite. The simulation includes encoding and decoding of navigation message. This simulation is created in Matlab version 7.4 environment.

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.
