Unmanned aerial systems (UAS), also known as drones, are aircraft systems that operate without a human pilot on board. These systems have gained popularity in various industries for applications such as surveillance, reconnaissance, aerial photography, package delivery, agriculture monitoring, search and rescue operations, and more. UAS technology has rapidly advanced in recent years, leading to improved capabilities, longer flight times, and increased payload capacities. Research in this area focuses on developing new UAS designs, improving autonomous navigation and control systems, enhancing sensor capabilities, optimizing energy efficiency, and addressing regulatory and ethical concerns surrounding their use.
