Processing of localization data and its accuracy
Návara, Marek ; Chromý, Adam (referee) ; Jílek, Tomáš (advisor)
This work is focused on correction of localization data, relative to them location of the sensor on robot. Also solves the conversion between coordinate systems WGS-84, ETRS-89 and local coordinate system. For localization data are designed error characteristics and thier transformation.These points have been implemented in C# as individual classes for position sensors and sensors orientation. Classes were firstly developer for single-axis sensors and they are base for multi-axis sensors. The implementation has been verified in the experiment with the robot envMap. Experiment results show that the correction is implemented properly and can be further used. Error characteristics listed in the work characterize the measurement uncertainty of location data and can be used in further processing.

Development of astronomical telescope control system with satellite tracking
Juráň, Jakub ; Musil, Vladislav (referee) ; Háze, Jiří (advisor)
The focus of this thesis is a development of an electronic guiding unit for a mount of an astronomical telescope allowing observations of artificial satellites orbiting the Earth. It contains a theoretical study of methods developed for the description of positions of objects observable on the celestial sphere, including systems used for storage of this information and regaining it in order to point the telescope in a specific direction. The work includes an analysis of the present supply of commercial devices, followed by a detailed description of the design developed here and its components. Finally, there is outline of possibilities of a future development of the system, focusing on software components.

Attitude and Heading Reference System
Chotaš, Kryštof ; International, - Honeywell (referee) ; Klusáček, Stanislav (advisor)
This thesis deals with inertial navigation systems issues. It describes basics of reference frames, coordinate systems and matrix calculations for AHRS. There are also basic information about inertial sensors, inertial measurements units and its mistakes. One of the purposes of this paper could be explanation of inertial navigation systems terms. The main object of this thesis is to explore the influence of using multiple sensors of same type to enhance measurements of AHRS systems.

Internet nodes localization using synthetic coordinate systems
Švéda, Jaroslav ; Jelínek, Mojmír (referee) ; Komosný, Dan (advisor)
This thesis deals with predicting the latency between two network nodes, such as the two stations, two servers or server and station. The main reason for adoption of effective latency prediction techniques is the elimination of network load caused by unnecessary repeated transmissios or by direct measurement of the latency. Of the many proposed methods of latency estimation, this thesis is focused on methods using artificial coordinate systems with primary focus on the Vivaldi algorithm. Characteristics of the latency prediction methods and properties of various coordinate systems used in practice are evaluated. The issue of the number of dimensions of space defined only by the latency matrix between nodes is also mentioned. Furthermore, some other systems, based on logical clustering of nearby nodes, are mentioned. Description of simulation software VivaldiMonitor developed as part of the thesis is included. The primary purpose is analysis of the behavior of overlay networks implementing Vivaldi algorithm with less than a few hundred nodes. The Vivaldi algorithm is assessed by several simulations carried out using the aforementioned software.

3D Demo for Holographic Display
Kulda, Lukáš ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
The result of this thesis is a 3D demo for holographic display visualizing satellite data on Earth surface. The Earth Engine API from Google was used to obtain visualized data. The 3D model scene and user interface were created using the Unity development environment and displayed on the Looking Glass holographic display to bring the scene into space.

Web-Based GPS and Meteorological Data Publishing System
Šoulák, Martin ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The objective of this bachelor thesis is to develop a web application for publishing and animating a route on hiking maps together with images obtained from a meteorological radar. The thesis includes the basics of the Earth surface description, coordinate systems, GPS and the meteorological radars. The next part of the text describes an analysis of available application interfaces for building rich web-based geographic applications. The application was developed in PHP with using the Javascript OpenLayers open-source library for creating a dynamic map in the web page. The thesis also deals with the problem of different coordinate systems used by the Mapy.cz portal and the recorded track points in a GPX file.
