Geofence¶
The geofence represents a hard limit to where the UAV will not fly beyond. It is useful for preventing runaway UAVs (barring other software/hardware issues). If it breaches the fence the failsafe will be activated, returning it to the home point.
It is represented as an arbitrary polygon of waypoints around the flying area in a fixed-wing vehicle. In ArduCopter, it is a radius and altitude parameter(s) representing a cylinder around the flying area.
A fence menu is available on the GUI console.
