ABSTRACT:
A spinning projectile is described including a roll rate sensor for providing a spin frequency signal, a nutation frequency signal and a precession frequency signal and a seeker for providing a boresight angle signal. The spinning projectile further includes a torquer assembly, responsive to a control signal, for selectively providing a force in a desired lateral direction and a digital signal processor, responsive to the spin frequency signal, the nutation frequency signal, the precession frequency signal and the boresight angle signal, for providing a control signal to the torquer assembly to control the desired direction of the force. With such an arrangement, a projectile is provided having greater maneuverability wherein an increase in maneuver footprint is obtained by having the maneuver force equal the sum of the rocket force and the body force rather than being a difference as in known projectiles.
