Abstract

Claims (27)

1 . A system comprising:

a processing unit configured to transition an unmanned aerial vehicle (UAV) from a first trajectory to impact a target to a second trajectory to avoid impact of the target by the UAV, wherein the transition is responsive to one or more of: an external command to transition the UAV from the first trajectory to the second trajectory and an indicator generated by onboard processing of the processing unit as an autonomous determination of scene change.

2 . The system of claim 1 , wherein the processing unit is configured to maintain a divert trajectory outside of a closed maneuver limit cone while in the first trajectory.

3 . The system of claim 2 , wherein the UAV is configured to transfer power from a battery of the UAV to a flight energy of the UAV in the divert trajectory.

4 . The system of claim 3 , wherein the divert trajectory is configured to transition the UAV from the first trajectory to the second trajectory.

5 . The system of claim 4 , wherein the UAV is configured to achieve at least an altitude in the second trajectory as the altitude at a start of the first trajectory.

6 . The system of claim 2 , wherein the processing unit is configured to store at least one of: a pre-terminal commit point and a return waypoint, wherein the processing unit is configured to transition the UAV to at least one of: the pre-terminal commit point and the return waypoint in response to an external command to transition the UAV from the first trajectory to the second trajectory, wherein the external command is configured to cause the processing unit to transition from the first trajectory to the second trajectory, and wherein the external command is configured to be received via an uplink receiver.

7 . The system of claim 2 further comprising:

one or more sensors, wherein the one or more sensors are configured to detect at least one of: a UAV position, a UAV linear velocity, a UAV rotational velocity, a UAV linear acceleration, and a UAV attitude.

8 . The system of claim 2 , wherein the processing unit is configured to transition the UAV from the first trajectory to the second trajectory via the divert trajectory.

9 . The system of claim 2 , wherein the first trajectory further comprises homing on a target to deliver a payload into a target volume.

10 . The system of claim 9 , wherein the second trajectory is configured to avoid the UAV impacting the target volume.

11 . The system of claim 9 wherein the second trajectory is configured to avoid the UAV impacting at least one of: the target the UAV is homing on and the ground.

12 . The system of claim 2 , wherein the divert trajectory is outside of a toroidal volume disposed about the UAV.

13 . The system of claim 1 , wherein the processing unit comprises at least one of: a central processing unit configured to execute computer-executable instructions; electrical circuitry; electronic circuitry; and a logical gate array.

14 . The system of claim 1 , wherein the indicator is configured to be received autonomously based on one or more image change conditions detected via a UAV onboard targeting sensor.

15 . A method comprising:

transitioning, by a processing unit, an unmanned aerial vehicle (UAV) from a first trajectory to impact a target to a second trajectory avoiding impact of the target by the UAV, wherein the transition is responsive to one or more of: an external command to transition the UAV from the first trajectory to the second trajectory and an indicator generated by onboard processing of the processing unit as an autonomous determination of scene change.

16 . The method of claim 15 further comprising:

maintaining, by the processing unit, a divert trajectory outside of a closed maneuver limit cone while in the first trajectory.

17 . The method of claim 16 further comprising:

transferring power from a battery of the UAV to a flight energy of the UAV in the divert trajectory, wherein the divert trajectory transitions the UAV from the first trajectory to the second trajectory, wherein the UAV achieves at least an altitude in the second trajectory as the altitude at a start of the first trajectory.

18 . The method of claim 16 , wherein the first trajectory further comprises homing on a target to deliver a payload into a target volume, and wherein the second trajectory avoids the UAV impacting at least one of: the target the UAV is homing on and the ground.

19 . The method of claim 15 further comprising:

testing, by the processing unit, for the indicator while in the first trajectory.

20 . The method of claim 19 further comprising:

receiving the indicator autonomously based on one or more image change conditions detected via a UAV onboard targeting sensor.
