Indoor localization based on UWB technology
Bauer, Jan Jiří ; Vyroubal, Petr (referee) ; Čech, Ondřej (advisor)
This bachelor thesis is exploring ways to localize an object in space, primarily using UWB technology. Diverse ways to determine distance (TWR, RSSI, TDoA), location in space (triangulation, multilateration, particle filter), and filters (LSM, Kalmann filter) are explained. Using development board ESP-32 UWP Pro localization system is realized, using TWR and particle filter. This system was calibrated and tested in a real environment.

Algorithm Development for Automatic Placement of Positioning System Reference Units
Průdek, David ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This diploma thesis describes designing and implementing the algorithm for automatic placement of the real-time localization system reference units. The algorithm is supposed to work with RTLS of the company Sewio Networks. The content of this thesis covers localization options in sensor networks and it is focused on UWB wireless technology. This thesis defines the use case of the designed feature and the principles of the most important parts for the correct outcome. Furthermore, the thesis contains implementing details and the way of integration into the Sewio RTLS. The last part presents the testing results of the created function and proposes future improvements.

UWB Locator
Jančiar, Marek ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
The subject of this work is the implementation and evaluation of the parameters of the localization system using UWB technology. This work focuses on two localization methods, namely TWR and TDoA. To compare the capabilities of UWB with other wireless techno- logy, this work also includes an implementation using BLE technology, specifically a method that uses the RSSI value. Parameters such as the accuracy or energy consumption of the implementation of these methods on specific hardware were practically measured and in- corporated into the text of this work. With the help of this work, the reader can create an image of the capabilities of the mentioned technologies and the way of implementing the localization methods.
