    DETEKCIA A OCHRANA OBJEKTOV PROTI PREVÁDZKE BEZPILOTNÝCH LIETADIEL
    (Žilinská univerzita v Žiline, 2020) Bujna, Erik; Škultéty, Filip
    The main topic of this bachelor thesis is the detection and protection of objects against the operation of unmanned aerial vehicles (UAVs). The necessity of addressing this issue is due to the increasing prevalence of UAVs and increase in reports of airspace penetrations by unauthorised UAV operations. The aim of the bachelor thesis is to analyse the problem and provide an overview of the possibilities and methods of protection against unmanned aircraft. The first part of the bachelor thesis provides a brief overview of the issue, including terminology, an overview of current legislation, the possibility of using unmanned aircraft together with incidents that have also become the subject of the problem. The following chapters examine in more detail the possibilities of detection and protection against unmanned aircraft. The comparative method compares the positive and negative aspects of individual detection methods. In the third chapter are provided specific solutions which are based on the methods of security protection and defined principles to operators of areas with the necessary security protection. The conclusion of the bachelor thesis includes the analysis of the Bratislava airport surrounding, the definition of the protective zones of airport together with the protective zones of navigation devices. The result is a proposal for implementation of detection system, which should to ensure regular and safe operation and to reduce the risk of flying unmanned aircraft over the airport. The proposal of securing the airport against UAVs offers the possibility to protect the nearest surroundings of the airport from the intrusion of unmanned aircraft and in case of disruption of the covered area of early warning and the possibility of responding to the threat.

    ANALÝZA AKTUÁLNYCH TRENDOV URČUJÚCICH SMER VÝVOJA BEZPILOTNÝCH PROSTRIEDKOV V CIVILNOM LETECTVE
    (Žilinská univerzita v Žiline, 2020) Butuk, Yosef; Ažaltovič, Viliam
    This paper describes the current situation in the field of flying unmanned aircraft. It characterizes the legislative conditions in the Slovak Republic and the European Union and the areas of use of unmanned aerial vehicles. The main objective of the work is to analyze current trends that may affect the development of unmanned aircraft in civil aviation. The work also includes innovations in the field of unmanned aerial vehicles that could be implemented in the future. The conclusion of the bachelor thesis summarizes the results of the current analysis and predicting the future development of UAVs.

    VYUŽITIE AUTONÓMNYCH SYSTÉMOV UAV PRE PODMIENKY ZÁCHRANNÝCH ZLOŽIEK
    (Žilinská univerzita v Žiline, 2020) Leitner, Martin; Pecho, Pavol
    The use of drones is slowly becoming an integral part of our lives. They are used every day and new ways of use are constantly emerging in various areas. One of the easiest way is to use them for entertainment, but there are also a large number of professional users. Their largest users include the military, but they are also used for aerial monitoring, mapping and various other services. As in civil aviation, as well as for UAV users, it is necessary to correct the current legislation, which is also included in the work. In the paper we will investigate the use of UAVs by armed force and rescue units. In this area, they have the opportunity to make full use of their main advantage, and that is how to get to places where access is difficult. In addition, their use does not require a pilot on board and does not endanger his life, as is the case with helicopters. In this work, we will design a flight path for a drone to cover the area as effectively as possible and thus help the rescue services to be more efficient in the search for missing persons. The flight path design will be created in the Dronedeploy program and will be planned for three types of terrain at different initial settings to allow comparison of these flights. Tables and figures are added to each flight to help the reader better understand the flight suggestions.

    OPTIMALIZÁCIA VYHĽADÁVANIA OSÔB ZA POMOCI TERMOVÍZNEHO SKENU PROSTRIEDKOV UAV
    (Žilinská univerzita v Žiline, 2020) Nosál, Ľubomír; Pecho, Pavol
    The main aim of the paper is to optimalize person search by using UAV with infrared camera. Author’s goal is to confirm experiment which he came up with and to also confirm theoretical knowledge about the discussed matter. The objective of the paper is to look at the problem from as many views as possible. Every point of view has to be analyzed and optimal solution for the problem should be found. In order to use technical devices one has to understand how the machines work and understand the basic pricinples which the machines are based on. Working principles of infrared cameras are interpreted also the radiation which every object emits and which the camera scans is described. In the master paper are analyzed study cases from real search and rescue missions. The solutions of these study cases are proposed by using UAV with infrared camera. The most important part of the paper is the experimenthal phase. The optimal angle which the camera is mounted under the UAV is solved and discussed. Also the factors which affect the camera during the flight are evaluated. At the end of the paper one can find concept how to fight COVID-19 by using knowledge acquired from the paper.

    RIEŠENIE VTOL PRE UAV S FIXNÝMI NOSNÝMI PLOCHAMI
    (Žilinská univerzita v Žiline, 2020) Sisák, Tomáš; Škultéty, Filip
    This paper focuses on solving the problem of vertical takeoff and landing of an unmanned aerial vehicle with fixed bearing surfaces. The introduction describes the two most commonly used types of UAVs, emphasizing the positive and the negative properties of the UAVs. Furthermore, the work describes vertical takeoff and landing of aircraft and the design of the arrangement of airfoils and fuselage for individual UAV. The next chapter focuses on the selection of correct material and the process of building a UAV. The following chapter is devoted to the used electronics, describing each component separately, but at the same time, describing the electronic components necessary for the vertical takeoff and landing of the so-called pixhawk precisely. The main idea is to introduce the functioning of the sole component and the correct setting using a computer program. At the end of the work, there are calculations that are necessary to determine the operating values such as the speed range and the multiples for safe operations of the UAVs. These calculations are obtained computationally but also by simulation, using the XFLR5 program. With the help of this paper, reader can build, set up and fly with an unmanned aerial vehicle with fixed surfaces and vertical takeoff and landing by himself..
