Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for unmanned aerial vehicle authorization and geofence envelope determination. One of the methods includes determining, by an electronic system in an Unmanned Aerial Vehicle (UAV), an estimated fuel remaining in the UAV. An estimated fuel consumption of the UAV is determined. Estimated information associated with wind affecting the UAV is determined using information obtained from sensors included in the UAV. Estimated flights times remaining for a current path, and one or more alternative flight paths, are determined using the determined estimated fuel remaining, determined estimated fuel consumption, determined information associated wind, and information describing each flight path. In response to the electronic system determining that the estimated fuel remaining, after completion of the current flight path, would be below a first threshold, an alternative flight path is selected.

First claim

What is claimed is:

1. An unmanned aerial vehicle (UAV) system, comprising one or more processors and one or more computer storage media storing instructions that are operable, when executed by the one or more processors, to cause the one or more processors to perform operations comprising:
displaying, via a user interface, a current flight path of the UAV;
determining based on information a contingency prediction of the UAV to recommend an alternative flight path for the UAV;
displaying, via the user interface, the alternative flight path for the UAV; and
performing the alternative flight path for the UAV.

2. The system of claim 1 , wherein the current flight path includes a plurality of waypoints and the alternative flight path excludes one or more waypoints from the current flight path.

3. The system of claim 1 , wherein the information includes estimated fuel remaining and estimated fuel consumption.

4. The system of claim 3 , wherein the estimated fuel remaining is battery charge and the estimated fuel consumption is power consumption.

5. The system of claim 3 , wherein the UAV periodically determines the estimated fuel remaining.

6. The system of claim 1 , wherein the contingency prediction is an estimated insufficient fuel situation such that the UAV would be unable to perform the current flight path.

7. The system of claim 1 , wherein the operations further comprise:
receiving an approval of the alternative flight path for the UAV.

8. The system of claim 1 , wherein the operations further comprise:
determining at least an updated landing location for the alternative flight path or determining a minimum safe altitude for the alternative flight path.

9. The system of claim 1 , where the alternative flight paths includes a flight path to return to a point of takeoff location.

10. A method, comprising:
displaying, via a user interface, a current flight path of an unmanned aerial vehicle (UAV);
determining based on information a contingency prediction of the UAV to recommend an alternative flight path for the UAV;
displaying, via the user interface, the alternative flight path for the UAV; and
performing the alternative flight path for the UAV.

11. The method of claim 10 , wherein the current flight path includes a plurality of waypoints and the alternative flight path excludes one or more waypoints from the current flight path.

12. The method of claim 10 , wherein the information includes estimated fuel remaining and estimated fuel consumption.

13. The method of claim 12 , wherein the estimated fuel remaining is battery charge and the estimated fuel consumption is power consumption.

14. The method of claim 12 , wherein the UAV periodically determines the estimated fuel remaining.

15. The method of claim 10 , further comprising:
receiving an approval of the alternative flight path for the UAV.

16. The method of claim 10 , further comprising:
determining at least an updated landing location for the alternative flight path or determining a minimum safe altitude for the alternative flight path.

17. A computer program product, encoded on one or more non-transitory computer storage media, comprising instructions that when executed by a system, comprising one or more computers, cause the system to perform operations comprising:
displaying, via a user interface, a current flight path of the UAV;
determining based on information a contingency prediction of the UAV to recommend an alternative flight path for the UAV;
displaying, via the user interface, the alternative flight path for the UAV; and
performing the alternative flight path for the UAV.

18. The computer program product of claim 17 , wherein the current flight path includes a plurality of waypoints and the alternative flight path excludes one or more waypoints from the current flight path.

19. The computer program product of claim 17 , wherein the operations further comprise:
receiving an approval of the alternative flight path for the UAV.

20. The computer program product of claim 17 , wherein the operations further comprise:
determining at least an updated landing location for the alternative flight path or determining a minimum safe altitude for the alternative flight path.
