Unmanned Aircraft Systems (UAS), commonly known as drones, are aircraft that operate without a human pilot on board. They consist of a flying vehicle, often equipped with cameras or sensors, and a ground control station that allows operators to control the aircraft remotely. UAS are used in various fields, including agriculture, surveillance, and delivery services. These systems can vary in size and capability, from small hobbyist drones to larger models used for commercial purposes. UAS technology has advanced significantly, enabling features like autonomous flight and real-time data transmission, making them valuable tools for both recreational and professional applications.
