Abstract

Systems, methods, and devices are provided for providing flight response to flight-restricted regions. The location of an unmanned aerial vehicle (UAV) may be compared with a location of a flight-restricted region. If needed a flight-response measure may be taken by the UAV to prevent the UAV from flying in a no-fly zone. Different flight-response measures may be taken based on the distance between the UAV and the flight-restricted region and the rules of a jurisdiction within which the UAV falls.

First claim

What is claimed is:

1. An unmanned aerial vehicle comprising:
one or more processors individually or collectively programmed to (1) obtain a location of the unmanned aerial vehicle, (2) calculate a distance between the location of the unmanned aerial vehicle and a flight restricted region, and (3) assess whether the distance falls within a distance threshold, wherein the one or more processors, individually or collectively, are further programmed to permit taking off of the unmanned aerial vehicle when the distance exceeds the distance threshold, and prevent taking off of the unmanned aerial vehicle when the distance falls within the distance threshold; and
one or more propulsion units in communication with the one or more processors, the one or more propulsion units configured to effect the taking off of the unmanned aerial vehicle in response to one or more signals instructing the taking off of the unmanned aerial vehicle.

2. The unmanned aerial vehicle of claim 1 , wherein the location of the unmanned aerial vehicle comprises coordinates of the unmanned aerial vehicle at rest on a surface.

3. The unmanned aerial vehicle of claim 1 , wherein the location of the unmanned aerial vehicle is approximated using coordinates of an external device in communication with the unmanned aerial vehicle.

4. The unmanned aerial vehicle of claim 3 , wherein the coordinates of the external device are received with aid of a GPS signal at the external device.

5. The unmanned aerial vehicle of claim 3 , wherein the external device is a mobile terminal capable of receiving data from the unmanned aerial vehicle.

assessing, with aid of the one or more processors, whether the distance falls within a distance threshold; and
preventing, with aid of the one or more processors, the unmanned aerial vehicle from taking off when the distance falls within the distance threshold.

16. An unmanned aerial vehicle comprising:
one or more processors individually or collectively programmed to (1) obtain a location of the unmanned aerial vehicle, (2) calculate a distance between the location of the unmanned aerial vehicle and a flight restricted region, and (3) assess whether the distance falls within a distance threshold, wherein the one or more processors are further programmed to effect automatic landing of the unmanned aerial vehicle when the distance falls within the distance threshold; and
one or more propulsion units in communication with the one or more processors, the one or more propulsion units configured to effect the automatic landing of the unmanned aerial vehicle in response to one or more signals instructing the landing of the UAV.

17. The unmanned aerial vehicle of claim 16 , wherein the location of the unmanned aerial vehicle is received with aid of a GPS signal at the unmanned aerial vehicle.

18. The unmanned aerial vehicle of claim 16 , further comprising a local memory that stores the location of the flight-restricted region and further stores locations for a plurality of flight-restricted regions.
