International ClassF41G 007/34Foreign Application Priority Data1997-09-17 DEAbstractA 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 ࣙ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.Field of SearchMISSILE STABILIZATION OR TRAJECTORY CONTROLRemote control Automatic guidance Optical (includes infrared) Radio wave Inertial Sliding Externally mounted stabilizing appendage (e.g., fin) Radially rotating Stabilized by rotation Attitude control mechanisms Removable Longitudinally rotating Collapsible Fluid reaction type | |
