UNMANNED AERIAL VEHICLE ANGULAR REORIENTATION
First Claim
1. An unmanned aerial vehicle (UAV) comprising:
- a processor having addressable memory, the processor configured to;
determine a body roll angle error based on a target location in a body reference frame and an orientation of the UAV in the body reference frame; and
determine one or more aileron actuator commands based on the determined body roll angle error.

Abstract
A system comprising an unmanned aerial vehicle (UAV) having wing elements and tail elements configured to roll to angularly orient the UAV by rolling so as to align a longitudinal plane of the UAV, in its late terminal phase, with a target. A method of UAV body re-orientation comprising: (a) determining by a processor a boresight angle error correction value bases on distance between a target point and a boresight point of a body-fixed frame; and (b) effecting a UAV maneuver comprising an angular role rate component translating the target point to a re-oriented target point in the body-fixed frame, to maintain the offset angle via the offset angle correction value.

10. A method of unmanned aerial vehicle (UAV) body re-orientation comprising:
-
determining , by a processor, a boresight offset angle error correction value based on a distance between a target point and a boresight point of a body-fixed image frame; and effecting, by the processor, an onboard control surface actuation maneuver comprising an angular roll component to translate the target point in the body-fixed frame to thereby maintain the offset angle via the offset angle correction value. - View Dependent Claims (11)
