The system and method of spin stabilizing a guided munition where a motor provides necessary de-spinning torque. The despun PGK portion of a guided projectile is already at high rate of spin relative to the projectile body and the motor is operated to maintain that rate. The spin stabilization system comprises at least a pair of permanent magnets embedded into a spinning section, at least one reflective reference marker on the spinning section, a pair of coils, and an optical encoder to detect the reflective reference marker. The spinning stabilization system also includes a powered controller with a timer and transistor.

    Système et procédé de stabilisation de rotation d'une munition guidée dans lesquels un moteur produit le couple de freinage de rotation nécessaire. La partie PGK à rotation freinée d'un projectile guidé se trouve déjà à une vitesse de rotation élevée par rapport au corps du projectile et le moteur est exploité pour maintenir cette vitesse.
