A cannon launched guided projectile having a gyro based electro-optical target finding and guidance system which includes an optical system carried by a gyro to provide target location information for an electronic system to produce gyro rotor torquing signals and for producing projectile guidance signals from gyro pickoff outputs is disclosed. The electronics system includes two difference channels for processing pitch and yaw signals responsive to the electrical output of a light detector and a sum channel for controlling the two difference channels responsive to target acquisition and master trigger signals.

A method for guiding to a target a cannon launched guided projectile having a timer, stabilizing fins, a direction finding signal processor electronic means, a gyro-optical system, a gyro, an electrical drive means and projectile guidance means comprising: (a) activating the timer upon setback to time an unguided portion of the projectile\s trajectory; (b) deploying the stabilizing fins during the unguided portion of the projectile\s trajectory to stabilize the projectile against spin; (c) sequentially activating the direction finding signal processor electronic means to determine, responsive to signals generated by the gyro-optical system, target acquisition, while delaying the output of projectile guidance signals of the processor electronic means and during the delay, activating the gyro of the gyro-optical system and the projectile guidance means; (d) precessing the gyro through pitch and yaw signals received from the direction finding signal processor to align the gyro with the target; (e) providing pitch and yaw angle signals from the direction finding signal processor electronic means for producing pitch and yaw guidance signals; and (f) applying the pitch and yaw guidance signals to an electrical drive means to selectively actuate the projectile\s guidance means to align the projectile with the target.
