What is the difference between a UAV and a UAS?

The distinction between a UAV (Unmanned Aerial Vehicle) and a UAS (Unmanned Aerial System) lies mainly in their definitions and components. A UAV refers specifically to the aerial vehicle itself, the actual drone that is used for flying. In contrast, a UAS encompasses a broader system, which includes not just the UAV but also the components necessary for its operation, such as ground control stations, the communication links, and sometimes additional support equipment. This comprehensive view of the UAS encapsulates everything needed to conduct a mission involving the UAV, making option A the most accurate choice.

Understanding this distinction is essential for professionals in GIS and related fields, as it clarifies the operational framework within which UAVs are deployed. While UAVs are critical for capturing aerial data, the complete UAS system integrates human decision-making and technological support, enhancing the overall functionality and effectiveness of aerial data collection missions.
