What does the term "geofencing" refer to in UAS technology?

The term "geofencing" in UAS technology refers to a virtual boundary that prevents a UAS from flying into prohibited or restricted areas. This is particularly important for ensuring safety and compliance with regulations, as unmanned aircraft systems must avoid specific zones where their operations could pose risks, such as near airports, military installations, or sensitive wildlife habitats.

Geofencing uses GPS or RF technology to create these virtual boundaries. When a drone approaches a designated restricted area, its onboard systems will recognize the geofencing parameters and take appropriate actions, such as stopping the flight, returning to its launch point, or rerouting to a safer location. This functionality is crucial for both regulatory adherence and the overall safety of UAS operations.

The other choices do not accurately describe geofencing functions. A virtual boundary that enables UAS to fly freely does not align with the purpose of geofencing, which is about restricting access. A physical barrier does not reflect the digital nature of geofencing. Lastly, while flight speed is a critical aspect of UAS performance, geofencing is unrelated to speed enhancements; its primary role is ensuring safe navigation within designated airspace.
