Unmanned Aircraft Systems (UAS) refer to aircraft that operate without a human pilot on board. These systems, commonly known as drones, are controlled remotely or autonomously and have a wide range of applications in fields such as military, agriculture, surveillance, monitoring, and disaster response. Research in the area of UAS focuses on improving their capabilities, safety, efficiency, and integration into the national airspace system. Additionally, researchers are exploring new technologies and techniques to enhance UAS performance, increase their autonomy, and address regulatory and ethical considerations.
