Patent ID: 7963442

Claim:
An apparatus for controlling a trajectory of a projectile, comprising: a first section disposed on the projectile having a longitudinal axis that is at an axial offset with respect to a longitudinal axis of a projectile body and that rotates about the longitudinal axis of the projectile body; a second section disposed on the projectile that rotates about the longitudinal axis of the projectile body and is rotationally decoupled from the first section; and an on-board processor that controls rotation of the first section and rotation of the second section, wherein the on-board processor receives trajectory information during flight of the projectile and controls the rotations of the first section and the second section to adjust a predicted impact point of the projectile with respect to target coordinates, wherein a direction of the longitudinal axis of the first section is adjustably controllable by the on-board processor, independently of a direction of the longitudinal axis of the projectile body, using the rotations of the first section and the second section to control the trajectory of the projectile during the flight, and wherein a magnitude of an angle of deflection of the longitudinal axis of the first section with respect to the longitudinal axis of the projectile body is caused by the decoupled rotations of the first section and the second section during the flight.
