    (University of Žilina, 2024) Bejdáková, Natália; Pecho, Pavol
    Unmanned aerial vehicles are a dynamically developing industry. With the increasing number of remotely piloted aircraft, emphasis is being placed on ensuring safe operation in shared airspace with manned aircraft. In the countries of the European Union, including Slovakia, the concept of U-Space is gradually being implemented. The bachelor thesis is focused on the analysis of the current situation in the operation of unmanned aircraft, current legislation, operation rules, and implementation of the U-Space concept in Slovakia. Attention is being concentrated on explaining the concept of U-Space and defining the services, including the responsibilities and obligations of the entities present in this system. The thesis proposes a set of possible implementation solutions to ensure more efficient and faster development in Slovakia. Based on relevant proposals, specific examples of how the situation would change after the implementation of the selected proposals are pointed out. An analysis of the findings based on collected data from the questionnaire is given to determine the level of awareness of the U-Space concept and the improvement of the educational situation in Slovakia. Finally, the technical and economic aspects of U-Space implementation are being evaluated and possible pros and drawbacks are identified.

    Danger of icing when operating unmanned aerial vehicles
    (University of Žilina, 2022) Ondrejková, Ivana; Kandera, Branislav
    The paper examines icing on Unmanned Aerial Vehicles (UAV) during the flight. We chose the Mavic Pro and Mavic 2 Pro UAV by company DJI to carry out the research. Research flights are performed during the early morning hours with meteorological conditions suitable for icing. We use the AirData application to analyse flight data. The aim of the work is to find out how dangerous icing is, what meteorological conditions are suitable for icing, how fast icing is formed during the operation of an unmanned aircraft and how it is possible to suppress or eliminate icing. In introduction of this work elaborated theoretical knowledge about the formation of icing and its types. Subsequently, the negative effects of icing on the flight are described, such as changes in lift, drag, controllability of the aircraft and others. The following section describes the accidents of UAV due to the impact of icing. After analysing the data from the mentioned application, we proposed recommendations for pilots of UAV. Before the flight, we recommend checking the meteorological forecast, focusing on the temperature and humidity at the flight area, usually up to 120 meters above the Earth surface. In-flight recommendations include monitoring rotation speed of propellers and frequent inspection of propellers in meteorological conditions suitable for icing and others.

    Design of UAV detection system utilizing communication monitoring
    (University of Zilina, 2021) Brodniansky, Martin; Novák, Andrej
    Aim of the paper is to design a system capable of detecting unmanned aerial vehicles utilizing radio communication sensing. The need to detect UAVs is caused by combination of their compact size, sensing capabilities, autonomous nature, ways of misusing them or their spread among unprofessional users unaware of their own risky handling of UAV. All these factors can lead to serious security threats and risk to human lives or infrastructure. In this paper, radio communication detection system is proposed as part of a robust system where radio detection is supplemented by other methods, to maximise probability of UAV detection. Significant attention was dedicated to deeper analysis of current progress in the area of radio communication detection systems as well as acoustic, visual and radar detection. Based on this analysis, all systems were compared together based on probability of detection and distances of detection. Comparation together with different properties of detection methods were basic stepping stone for final system proposal. Robust detection system was successfully designed with radio detection as its primary component, radar detection serving primarily as localizer of UAV, acoustic system serving as backup for detection of UAVs without radio communication and visual system for final confirmation of UAV, its model and presence of camera or load
