Unmanned Aircraft Systems

lt;p>This spin-off hardback volume, is devoted to the current state-of-the-art and recent advances in Unmanned Aircraft Systems (UAS). The area of UAS has seen unprecedented levels of growth over the last decade, and it is also expected to be one of the most dominant areas of research and development in the future. Although the main focus of UAS applications was in military domains, we now see a shift of UAS use in civilian/public domains. However, it will be long before UAS are extensively utilized in civilian domains, but their importance in applications related to earth science, environment/pollution monitoring, land management, civil infrastructure, health management, public security, fire detection, emergency response, search and rescue, etc., is obvious. Despite the tremendous progress in UAS, there are still major challenges and obstacles to be overcome, which relate, among other things, to: navigation, control and communication issues; levels of autonomy; fault-tolerance; sensors; payloads, range and endurance, and, integration of UAS into the national airspace. This volume aims at discussing some of the current challenges in UAS by publishing peer reviewed, archive and original papers from research groups all over the world. The papers have been divided in the following areas: UAS operations, regulations and airworthiness; Energy efficient UAV systems and UAS management; UAV design, modeling and validation; UAV control; UAV mission and path planning; UAV tracking; UAV vision systems and vision-based navigation; Quadrotor UAVs; Micro Air-Vehicles (MAVs); UAV formations and swarms; Cooperative UAVs; UAS testbeds; and Applications. The list of topics is by no means exclusive and complete, but it does provide an indication of the wide spectrum of problems scientists, researchers and engineers work on. An important part of this volume is conducted research in cooperative UAVs and UAV formations, which hints a move from a single UAV to multiple UAVs. Regardless, the list of topics is very wide and diverse, and the Applications section papers give the reader nothing but an idea of where UAVs may be used.
