DJI geofencing uses GPS and other navigational satellite signals to automatically help prevent drones from flying near sensitive locations such as airports, prisons, nuclear power plants and high-profile events. In certain locations, a DJI drone cannot take off within, or fly into, a geofenced area without special authorisation. Drone pilots with verified DJI accounts can unlock some areas if they have legitimate reasons and necessary approvals, but the most critical areas require extra steps from DJI to unlock them. DJI has streamlined the approval process so professional drone pilots with authorisation to fly in sensitive locations can receive unlocking codes within 30 minutes by submitting a request online.
