A method for the autonomous guidance of a spin-stabilized artillery projectile (2; 25) toward a target (12). To ensure that an autonomously guided, spin-stabilized artillery projectile (2; 25) hits a target (12) with high precision, even at distances of .gtoreq.35 km, previously determined target data are transmitted to the projectile (2; 25) and stored therein before it is fired, and, following the firing of the projectile (2; 25), these stored data are compared with projectile position data, detected with the aid of a satellite navigational receiving station (23). The correction data resulting from this comparison are then used for the projectile (2; 25) guidance. Shortly before reaching the guidance phase, the velocity of the projectile is reduced by the use of spin-stabilized brakes and the projectile flight is changed for purposes of guidance from a spin-stabilized to a fin-stabilized flight state, wherein the projectile (2; 25) is then guided aerodynamically by means of rotating fins (9), arranged on the nose side, which can swing out, and wherein the spin-stabilized brakes function as lift surfaces once they are locked in place.

[ What is claimed:] [4.] An autonomously guided, spin-stabilized artillery projectile, comprising:a) a projectile body;b) a parachute brake that is jettisonable and a spin-stabilized brake, composed of several fold-out fins, arranged at a tail region of the artillery projectile body,c) a plurality of rotating fins, designed for the projectile guidance, located in front of a mass center of the projectile and distributed over the circumference of the projectile body, with the fins being mounted to be pivoted outwardly via servomotors and to be swing back and fitted, via slots in the circumference of the projectile body, into the projectile body;d) at least one satellite navigational receiver system arranged in the projectile body as a sensor for determining the projectile position; and,e) an electronic control device which is disposed in the projectile body and which determines trajectory correction data, as well as the respective roll position of the projectile from target data transmitted to this projectile prior to firing and stored in a memory of the device as well as from projectile position data determined during flight by the satellite navigational receiver system, and which then determines control data for the servomotors during a guidance phase from the resulting data and subsequently transmits said control data to the servomotors for guiding the projectile after it has slowed down, the spin-stabilization of the projectile has ended and the rotating fins are extended.
