Which term describes delineating geographic boundaries to enforce safe UAS operations?

• A. Waypoints
• B. Orbit
• C. Satellite Link
• D. Geo-fencing

Answer: (D)

Delineating geographic boundaries to enforce safe UAS operations involves creating virtual fences around areas where flying is restricted or requires special authorization. This approach is called geo-fencing. By establishing these boundaries, a drone’s control system can warn the operator or automatically prevent flight into restricted zones, or trigger a safe action like returning to home or landing if the boundary is crossed.

Waypoints are just specific navigation points used to guide a flight path; they define where the drone should go, but they don’t establish enforced geographic limits on a wider area. An orbit describes a circular flight path around a point, which is a mission pattern rather than a boundary. A satellite link refers to how data is transmitted between the drone and its controller or base, not to enforcing geographic restrictions.
