Item Využitie mobilných sietí pre ovládanie a prenos videa z UAV(University of Žilina, 2025) Harasin, Adrián; Novák, AndrejUnmanned Aerial Vehicles (UAVs) are increasingly used in various fields, with reliable communication and data transmission being key aspects of their effective deployment. This paper explores the use of mobile networks for remote UAV control and real-time video transmission. It analyzes the advantages and limitations of different mobile network generations, particularly 4G LTE and 5G, in terms of latency, stability, and bandwidth. The results highlight optimization possibilities and potential applications of mobile networks in areas such as monitoring, security operations, and autonomous systems. Additionally, the thesis examines technological challenges and security aspects that impact the reliability of this solution.Item Urban Air Mobility ako ďalšia dimenzia dopravy v mestách(University of Žilina, 2025) Malaník, Artúr; Novák, AndrejThis thesis analyzes Urban Air Mobility (UAM) as an innovative solution to urban transport challenges in the EU, focusing on technologies, infrastructure, regulations, and benefits for transport and logistics. UAM, utilizing eVTOL aircraft, can reduce traffic congestion, create jobs, and lower CO2 emissions. In the EU, countries like France and Germany lead in infrastructure development and certification of models like Volocopter VoloCity. UAM could generate 90,000 jobs and a market value of 4.2 billion EUR by 2030, while cutting emissions by up to 52% per passengerkilometer. In logistics, it shortens delivery times to 15–30 minutes and reduces costs by 20–30%. Mathematical modeling estimates UAM adoption at 0.5–2% of trips in London could save 31–124 minutes annually per driver. Challenges include high vertiport costs (500,000–2 million EUR), regulatory harmonization, and public safety concerns. Recommendations include infrastructure investments, unified regulations, and public campaigns to enhance acceptance.Item Analýza využitia lietadiel ľahších ako vzduch na obchodnú leteckú prevádzkovú činnosť a analýza prechodu lietadiel ľahších ako vzduch z pilotovaných na bezpilotné(University of Žilina, 2025) Sabadoš, Marek; Novák, AndrejThis bachelor thesis includes a breakdown of definitions related to the classification of aircraft, primarily into lighter-than-air and heavier-thanair categories. The theoretical section focuses on the history and development of lighter-than-air aircraft. The next section discusses the technological challenges and regulatory requirements for transitioning from manned to unmanned lighter-than-air aircraft. In the final section, the economic efficiency and environmental impact of lighter-than-air aircraft are compared with heavier-than-air aircraft. The Skyship 600 and Cessna 208B Grand Caravan G1000 are specifically compared. Lastly, we assess these aircraft in the context of photogrammetry, forest liming, and environmental monitoring of habitats.Item Detekcia rušenia GNSS signálu prostredníctvom ADS-B prijímačov(University of Žilina, 2025) Trnkus, Oliver; Novák, AndrejIn this thesis, the detection of GNSS interference by ADS-B receivers and its impact on the accuracy of air navigation is investigated. GNSS systems are important for modern aviation and can be jammed, which threatens the safety of air traffic. ADS-B is a GNSS dependent system which allows monitoring and identification of areas of increased interference. As GNSS jamming events become more frequent, there is an increasing need for reliable approaches to detect jamming and minimise its impact. ADS-B can help to identify unusual deviations in navigation and contribute to improving the safety of air traffic. The survey highlights the need to protect GNSS signals and develop technologies for their detection.Item Měření parametrů větru na palubě ultralehkého letadla(University of Žilina, 2025) Kaltman, Lukáš; Novák, AndrejThis article addresses the issue of measuring wind parameters onboard ultralight aircraft with the aim of increasing pilot safety by providing relevant information about current weather conditions, specifically wind speed and direction. The theoretical part of the article analyzed the influence of wind on the flight characteristics of ultralight aircraft and examined existing wind monitoring options. Subsequently, an analysis of aircraft accident and incident data involving ultralight aircraft in the Czech Republic and Slovakia between 2019 and 2023 was conducted, revealing that wind negatively influenced 41 % of the analyzed events in the Czech Republic. Based on these findings, three potential solutions were proposed: establishing RADIO service at airfields for sport flying devices, installing windsocks at the ends of runways, and installing onboard electronic flight instrument systems capable of indicating the wind component. Using multi-criteria analysis, the installation of onboard instruments was evaluated as the most suitable option, as it offers the most accurate and up-to-date information directly during flight. In the experimental part, this option was preliminarily verified through two control flights at Sazená airfield using Garmin G3X systems. Comparison of data from the onboard instrument with data from ground meteorological stations showed that while the first flight yielded unrealistic results, the second flight showed better agreement, especially for wind direction, and the data from the onboard instrument corresponded more closely with the pilot's observations and the METAR report. It was concluded that onboard systems represent a promising solution, but more extensive research is necessary for definitive confirmation of their reliability. The article successfully identified a key risk factor, proposed a promising technical solution, and provided a theoretical and methodological basis for further research, thereby contributing to the main goal of increasing the safety of flying ultralight aircraft.Item Dopady emisných systémov na letecké spoločnosti(University of Žilina, 2025) Velčický, Ján; Novák, AndrejThis paper analyses the impact of emission systems on airline operations, with emphasis on EU measures (ETS, ReFuelEU) and global mechanisms (CORSIA). It compares regulatory frameworks, technological options and airline strategies in the context of reducing emissions by 2050. A combination of methods was used, including qualitative analysis of documents, scenario comparisons (LTAG), and quantitative assessment of economic effects. The findings show that EU tools alone are insufficient without additional measures. The thesis proposes a combined approach that integrates technological, operational and behavioral components, including fuel diversification, compensation schemes and innovative policies. The result is a realistic strategy for the decarbonization of European aviation, aligned with long-term targets and taking into account SAF, hydrogen, and infrastructure risks. The objective of the thesis to propose an effective decarbonization rajectory while minimizing financial impacts on carriers was achieved.
