Abstract

A vehicle control system and related sub-components together provide an operator with a plurality of specific modes of operation. The various modes of operation incorporate different levels of autonomous control. Through a control user interface, an operator can move between certain modes of control even after vehicle deployment. Specialized autopilot system components and methods are employed to ensure smooth transitions between control modes. Empowered by the multi-modal control system, an operator can manage multiple vehicles simultaneously.

Claims

1. A vehicle control system configured to accommodate command and control of a plurality of unmanned aerial vehicles (UAV'"'"'s) that are simultaneously in flight, the system comprising:

a transceiver that receives data from the plurality UAV'"'"'s and that transmits data to the plurality of UAV'"'"'s;

a situational display that provides real-time route information for the plurality of UAV'"'"'s and that supports real-time route editing for the plurality of UAV'"'"'s; and

wherein the system evaluates a revised route against a UAV performance capability and registers the revised route based on a determination that the revised route is within the UAV performance capability.

2. The vehicle control system of claim 1 wherein the system maneuvers one of the plurality of UAV'"'"'s according to the revised route.

3. The vehicle control system of claim 1 wherein the revised route comprises moving target tracking.

4. The vehicle control system of claim 1 wherein the situational display provides an operator with real-time information from a map perspective.

5. The vehicle control system of claim 1 wherein the plurality of UAV'"'"'s comprises at least two different types of vehicles.

6. The vehicle control system of claim 1 wherein an operator enters the revised route by graphically editing an existing route on the situational display.

7. The vehicle control system of claim 6 wherein graphically editing comprises adding an orbit pattern.

8. The vehicle control system of claim 6 wherein adding an orbit pattern comprises adding the orbit pattern in a vicinity of a desired target.

9. The vehicle control system of claim 1 wherein real-time route information for the plurality of UAV'"'"'s comprises a symbol for each of the plurality of UAV'"'"'s and a path for each of the plurality of UAV'"'"'s.

10. The vehicle control system of claim 9 wherein the path for each of the plurality of UAV'"'"'s includes an indication of where the UAV has been.

11. The vehicle control system of claim 9 wherein the path for each of the plurality of UAV'"'"'s includes an indication of where the UAV has been directed to go.

12. The vehicle control system of claim 1 wherein the revised route is automatically edited based on a determination that the revised route is not within the UAV performance capability.

13. A vehicle control system configured to accommodate command and control of a plurality of unmanned aerial vehicles (UAV'"'"'s) that are simultaneously in flight, the system comprising:

a transceiver that receives data from the plurality UAV'"'"'s and that transmits data to the plurality of UAV'"'"'s;

a selections panel for each of the plurality of UAV'"'"'s that allows an operator to switch between a range of different manual and autonomous control modes; and

wherein the system initiates a control mode for multiple of the plurality of UAV'"'"'s based at least in part on selections of different control modes from multiple of the selections panels.

14. The vehicle control system of claim 13 wherein the selections panel for each of the plurality of UAV'"'"'s is displayed independently on a graphical user interface and the selections panel allows the operator to switch between selection panels for each of the plurality of UAV'"'"'s.

15. The vehicle control system of claim 13 wherein one of the range of different control modes is sensor slave control.

16. The vehicle control system of claim 15 wherein at least one of the selections is made by inputting a parameter to be applied to a particular one of the range of different control modes.

17. The vehicle control system of claim 16 wherein the parameter includes a loiter point.

18. A vehicle control system configured to accommodate command and control of a plurality of unmanned aerial vehicles (UAV'"'"'s) that are simultaneously in flight, the system comprising:

a transceiver that receives data from the plurality UAV'"'"'s and that transmits data to the plurality of UAV'"'"'s;

a situational display that provides an operator with real-time route information for the plurality of UAV'"'"'s and that supports real-time route editing for the plurality of UAV'"'"'s;

a selections panel for each of the plurality of UAV'"'"'s that allows the operator to switch between various levels of manual and autonomous control modes for each of the plurality of UAV'"'"'s; and

a sensor control window for each of the plurality of UAV'"'"'s that enables selection of a data source and a sensor control.

19. The vehicle control system of claim 18 wherein the selectable data sources include video and simulated video sources.

20. The vehicle control system of claim 18 wherein the selectable sensor controls include automatic tracking, manual control, and fixed body manual control.
