    Using SDR receivers for UAV detection
    (University of Zilina, 2021) Dianovský, Robert; Novák, Andrej
    As the number of unmanned aerial vehicles (UAV) increases, new dangers arise for airports and other facilities. Because of this, the need for UAV detection and monitoring in areas, that might be endangered by their operation, is becoming an important topic. Introductory chapters are dedicated to the identification of potential risks posed by UAV operations and research of existing monitoring methods. The main goal of the paper, about which is this article, is to research the possibility of UAV detection by using accessible amateur SDR (Software-Defined Radio) for intercepting radio communications between UAV and its control station. Possible radio detection and localization methods were proposed based on the analysis of radio transmissions used in unmanned aerial systems. A simple theoretical design of SDR-based detection and localization system for monitoring unauthorized UAVs was developed by choosing appropriate methods. The principles and methods used in the design were experimentally demonstrated in several laboratory experiments. Successful realization of this design would possibly improve the availability of drone monitoring systems and reduce their production costs.

    The use of unmanned aerial vehicles in the mountain rescue service
    (University of Zilina, 2021) Gánovský, Martin; Kandera, Branislav
    The theme of paper is the use of unmanned aerial vehicles in the Mountain rescue service. At the beginning, a brief summary about the history and development of unmanned aerial vehicles is made, starting from the very beginning to their gradual integration into the rescue systems all around the world. This part is followed by an analysis of the currently valid Slovak legislation regulating the rules of flying with unmanned aerial vehicles on the territory of Slovak Republic, which also affects the flight operations of mountain rescuers. Author also included an analysis of the European legislation, which should gradually replace the currently valid Slovak legislation and unify the rules of operation of unmanned aerial vehicles on the territory of the member states. The third chapter describes the use of specific types of unmanned aerial vehicles used by the Mountain rescue service of Slovak Republic and also of other European countries. We focused on the operational advantages and disadvantages compared to other types of aircraft technology used in the mountain rescue systems. The last part consists of an analysis of available equipment used in conjunction with unmanned aerial vehicles during avalanche accidents. Part of the work is also researching the possible extensions of mountain rescue operations by the implementation of modern avalanche beacons attached on the unmanned vehicles. In a research we focused mainly on the possible interference caused by the operation of unmanned aerial vehicle in close vicinity of an avalanche beacon.

    Anti-collision systems of unmanned aerial vehicles
    (University of Zilina, 2021) Višnai, Kristián; Kandera, Branislav
    The main goal of the paper is to summarize the knowledge about anti-collision systems of unmanned aerial vehicles. In the work are also described currenly used anti-collision systems of unmanned aerial vehicles. The work contains practical research in which we tested anti-collision systems of DJI Mavic 2 Pro. The purpose of the research was to find out how this unmanned aerial vehicle can avoid static obstacles. The second part of practical research is the analysis and comparison of systems that provide anti-collision actvity between unmanned aerial vehicle and aircraft in the vicinity. Part of the work is also the evaluation and selection of a cooperative anti-collision system for DJI Inspire 2. The conclusion of the papercontains a summary of the findings that we have obtained based on the analysis of available facts and using operational experience.
