The increasing maturity of UAS technologies has transformed these systems from simple remotely piloted platforms into complex, autonomous and data-centric systems capable of supporting decision-making processes in dynamic and high-risk environments. This master’s thesis provides a comprehensive analysis of the technological evolution, operational capabilities and future prospects of UAS, with a particular focus on aerial photography, video acquisition and photogrammetry as core components of modern UAS applications. The study adopts a multidisciplinary perspective, combining technical, operational, regulatory and ethical dimensions, in order to assess the role of UAS as critical tools in contemporary crisis management and geospatial information systems. Fundamental Concepts and System Architecture The thesis begins with an overview of the fundamental concepts, definitions and classifications of UAS, highlighting the diversity of platforms and configurations currently in use. Fixed-wing, rotary-wing, hybrid and VTOL platforms are examined in relation to their operational characteristics, endurance, payload capacity and suitability for specific missions. Emphasis is placed on the notion that UAS should be considered as integrated systems rather than isolated aerial vehicles, comprising the aerial platform, onboard sensors, communication subsystems and ground control stations. The historical evolution of unmanned aerial systems is also discussed, tracing their origins from early military and experimental applications to their widespread adoption in civil and commercial domains. This evolution reflects both technological advances and changing operational requirements, particularly the growing demand for rapid data acquisition, flexibility and cost-efficient monitoring solutions. Sensors, Data Acquisition and Photogrammetry A central focus of the thesis lies in the analysis of sensors and data acquisition technologies employed by modern UAS. Optical, thermal, multispectral and LiDAR sensors are examined with respect to their capabilities and limitations, as well as their role in producing high resolution spatial data. Aerial photography and video acquisition constitute the primary sources of information, enabling real-time situational awareness as well as post-processing for detailed spatial analysis. Photogrammetry is highlighted as a key methodology for transforming UAS-acquired imagery into accurate geospatial products, such as orthophotos, digital surface models (DSM) and three-dimensional representations of terrain and infrastructure. The integration of UAS-based photogrammetry into Geographic Information Systems (GIS) significantly enhances the analytical potential of the collected data, enabling spatial visualization, temporal comparison and decision support in a wide range of applications. Technological Advances and Communication Systems The thesis further explores recent technological advances that shape the operational effectiveness of UAS. Artificial intelligence and machine learning techniques are increasingly integrated into UAS workflows, supporting automated object detection, image classification and adaptive mission planning. These capabilities contribute to the reduction of operator workload and enhance the autonomy of UAS, particularly in complex or time-critical missions. Special attention is given to communication systems, which constitute a critical enabling factor for modern UAS operations. The role of emerging technologies such as 5G and future 6G networks is examined in relation to low-latency data transmission and real-time video streaming. Additionally, mesh networks and Flying Ad Hoc Networks (FANETs) are analyzed as decentralized communication architectures that enable cooperative operation among multiple UAS, especially in environments lacking fixed communication infrastructure. Satellite communications are also discussed as a complementary solution for long-range and beyond-line-of-sight operations, particularly in remote or disaster-affected areas. The comparative evaluation of these communication architectures demonstrates that hybrid approaches, combining multiple technologies, offer the highest levels of reliability and operational resilience. Energy Autonomy and Power Management Energy autonomy is identified as one of the most significant constraints affecting UAS performance and mission duration. The thesis examines current energy storage technologies, including lithium-based batteries, as well as emerging alternatives such as fuel cells and hybrid power systems. The relationship between platform type, propulsion systems and energy consumption is analyzed, highlighting the trade-offs between endurance, payload capacity and operational flexibility. Energy management systems and intelligent control strategies play a crucial role in optimizing energy usage and extending mission duration. The integration of predictive algorithms and real-time monitoring allows for adaptive decision-making, such as mission replanning or coordinated operation among multiple UAS, which is particularly important in large-scale disaster response scenarios. Integrated Applications and Crisis Management A significant part of the thesis is devoted to integrated applications of UAS in aerial photography, video monitoring and photogrammetry for civil protection and disaster management. The ability of UAS to provide real-time visual information enhances situational awareness and supports rapid response during emergencies such as earthquakes, floods and wildfires. High-resolution imagery and video streams enable damage assessment, infrastructure monitoring and the coordination of emergency services. Beyond emergency response, UAS applications are examined in the context of smart cities, environmental monitoring and agricultural management. The combination of aerial data with GIS and cloud-based infrastructures enables continuous monitoring and long-term planning, reinforcing the role of UAS as essential components of digital and data-driven management systems. Ethical, Social and Environmental Considerations The widespread adoption of UAS also raises important ethical, social and environmental concerns. Issues related to privacy, data protection and surveillance are critically examined, particularly in urban environments where aerial monitoring may conflict with individual rights. The thesis emphasizes the importance of transparent regulatory frameworks, ethical guidelines and public awareness in ensuring the responsible use of UAS technologies. Environmental impacts, such as noise pollution and potential disturbances to wildlife, are also considered. While UAS can contribute to environmental protection through monitoring and data collection, their deployment must be carefully managed to minimize negative effects. Future Research Directions and Conclusions The final part of the thesis addresses future research directions and technological perspectives. Cooperative UAS swarms, advanced autonomous decision-making and the integration of aerial systems with terrestrial and space-based networks are identified as key areas of ongoing and future research. Advances in photogrammetric processing, sensor fusion and artificial intelligence are expected to further enhance the accuracy, reliability and applicability of UAS-derived data. In conclusion, this thesis demonstrates that Unmanned Aircraft Systems have evolved into indispensable tools for modern geospatial analysis, crisis management and environmental monitoring. Their effectiveness lies in the synergistic integration of aerial platforms, sensors, communication networks and data processing techniques. As technological innovation continues and regulatory frameworks mature, UAS are expected to play an increasingly central role in supporting informed decision-making and sustainable management practices across multiple domains."]},{"key":"dc:title","label":"Title","values":["Καινοτομίες και Μελλοντικές Κατευθύνσεις στα Συστήματα UASs"]}]}],"canonical_facts":{"dc:creator":["Ρήγας Γεώργιος","Rigas Georgios"],"dc:date":["2026"],"dc:description":["Τα Συστήματα Μη Επανδρωμένων Αεροσκαφών (Unmanned Aircraft Systems – UAS) αποτελούν μία από τις ταχύτερα εξελισσόμενες τεχνολογίες των τελευταίων δεκαετιών, με αυξανόμενη σημασία σε τομείς όπως η πολιτική προστασία, η διαχείριση φυσικών καταστροφών, η περιβαλλοντική παρακολούθηση, η γεωργία ακριβείας και η χαρτογράφηση.
