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.
Total Electron Content Measurements by SingleFrequency GPS Receiver
Rejfek, Luboš ; Pitaš, K. ; Urbář, Jaroslav ; Chmelař, P.
In this paper is described the measurement of the Total Electron Content by the single-frequency GPS receiver. Disadvantage of this method is that it cannot be used for realtime processing. The advantages of the proposed method are that the device is cheaper than dual-frequency GPS receiver and it can reinterpret older valuable measurements by such singlefrequency receivers. The algorithm was tested with the dualfrequency receiver. Signal from selected frequency (f1, or f2) was processed by presented algorithm and results were compared with standard processing of the signals, which is used for the dual-frequency receivers. Results are promising.
System for a Dispatching of a Private Ambulance Service
Prokop, Lukáš ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
This thesis deals with design and implementation of web application for a dispatching of a private ambulance service and mobile application for ambulance drivers. The web application allows the dispatcher to create new orders, plan routes effectively and assign them to ambulance vehicles. The mobile application is used for sending ambulance vehicle's position and displaying assigned routes. At the beginning of this thesis, the analysis of methods of web and mobile applications development, analysis of work with GPS data, analysis of system requirements and evaluation of existing solutions were performed. Web and mobile applications were designed and implemented on the basis of the information obtained. The implemented system emphasizes simplicity and intuitive control.
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.
Use GPS for in flight measurement
Čížková, Markéta ; Dvořák, Petr (referee) ; Jebáček, Ivo (advisor)
Bachelor thesis Use GPS for In-Flight Measurement addresses the applicability of Global Positioning System as a tool for aircraft certification. The theoretical part of thesis aims to acquire the GPS principle, it deals with accuracy of the system and methods of certification. The practical part contains a comparison of altitude measurement using GPS and Pitot-static system in a gliding flight.
Survey & comparison of operation principles of the existing kinds of GNSS
Pafkovič, Roman ; Sklenář, Filip (referee) ; Vosecký, Slavomír (advisor)
Master’s thesis deals with global navigation satellite systems. It gathers information about operation principles of individual systems and evaluates their applicability for Air transportation through own measures.
Digital controlled power source with GSM
Buday, Martin ; Streit, Jakub (referee) ; Bradáč, Zdeněk (advisor)
Content of this diploma thesis is project of the digital control design for a thyristor source with GSM communication. Designed for corrosion protection. The work contain design of the whole device from the initial proposals of the electro diagrams up to finished product. It describes the events that arise in corrosion, explains the principle of operating a thyristor as a power switch. It also describes the creation and structure of a simple menu using the STM32 microprocessor. It explains the principle of controlling a source. Next, it deals with controlled rectifiers using a thyristor.
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.
Analysis of ZED stereocamera in outdoor environment
Svoboda, Ondřej ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
The Master thesis is focused on analyzing stereo camera ZED in the outdoor environment. There is compared ZEDfu visual odometry with commonly used methods like GPS or wheel odometry. Moreover, the thesis includes analyses of SLAM in the changeable outdoor environment, too. The simultaneous mapping and localization in RTAB-Map were processed separately with SIFT and BRISK descriptors. The aim of this master thesis is to analyze the behaviour ZED camera in the outdoor environment for future implementation in mobile robotics.
Augmented Reality on Android - Displaying of Map Features in Terrain
Halás, Timotej ; Kapinus, Michal (referee) ; Herout, Adam (advisor)
The aim of this thesis is to create an application of augmented reality for Android operating system. Based on the preview from the camera, map data and the location of the device determined by the GPS module, a scene is created showing additional tourist information in the field. As a source of information and altitude data, the OpenStreetMap map and the Google Elevation API are used. The position in the Cartesian coordinate system is determined by geographic location using the WGS84 geodetic system. LibGDX game framework is used for rendering. The resulting application was tested in the field and it is useful in getting to know the surrounding landscape. It has also helped to navigate to points of interest by displaying their distance from the point of observation. The result of this thesis is an application suitable for exploring the observed environment.
