    Study of wireless communication links in the C-band and S-band for V-BAT type UAVs
    (ΔΙΠΑΕ, 2026-07-29) Angelopoulou, Maria-Stamatina; Αγγελοπούλου, Μαρία-Σταματίνα; Efstathiou , Dimitrios; Ευσταθίου, Δημήτριος; Πολυτεχνική Σχολή, Τμήμα Μηχανικών Πληροφορικής, Υπολογιστών και Τηλεπικοινωνιών
    Unmanned Aerial Vehicles (UAVs) have become important assets in modern military operations, providing Intelligence, Surveillance, and Reconnaissance (ISR) capabilities while reducing operational risk to personnel. The effectiveness of these systems depends strongly on the reliability and resilience of their communication links, which support both Command and Control (C2) and payload data transmission. This thesis examines the wireless communication links and network architectures used in tactical UAV systems, with emphasis on S-band and C-band frequencies used for line-of-sight UAV communication. The study analyzes the communication requirements of UAV operations, the propagation characteristics of these frequency bands, and the network architectures that enable reliable connectivity between the UAV and the Ground Control Station. Key communication technologies examined include wireless mesh networks, Mobile Ad Hoc Networks (MANET), and phased-array radio systems, with particular emphasis on directional beamforming techniques that enhance link reliability and improve resistance to interference. The V-BAT Vertical Take-Off and Landing (VTOL) UAV is used as a representative case study to illustrate how these communication technologies are implemented in practical UAV communication architectures. Finally, the thesis examines electronic warfare threats affecting UAV communication systems, including jamming, interception, and spoofing, and discusses mechanisms that improve communication resilience in contested electromagnetic environments.
