A system for target designation by laser comprises circuitry for precise alignment of the aircraft and pod lines of sight. The alignment circuitry operates digitally in a computer in which the director cosine data of the aircraft and pod lines of sight are compared to provide error signals fed to corresponding servo-controls. Alignment is obtained by the introduction of corrective data utilized for producing vector rotations, the corrective data being produced by means of a manually controlled stick device, integration circuits and a non-volatile memory.

An airborne target-designation system installed partly on an aircraft and partly on a pod carried by said aircraft, comprising: target-predesignation means aboard the aircraft for generating a first set of off-aim signals representing angular deviations of a first line of sight from a first reference direction based upon the structure of the aircraft; monitoring display means aboard the aircraft; automatic acquisition equipment in the pod including a laser illuminator and a pick-up camera trained upon a common second line of sight, said camera feeding video signals to said display means for producing thereon an image of a target lying on said second line of sight, said equipment further including orientation means controlled by first servo circuitry and operatively linked with optical means in line with said camera and said illuminator for keeping said second line of sight trained upon the target in response to said first set of off-aim signals in a search mode and in response to said video signals in a tracking mode, said orientation means generating a second set of off-aim signals representing angular deviations of said second line of sight from a predetermined second reference direction based upon the structure of the pod; selector means for establishing either one of said modes; and alignment means for correlating said lines of sight with each other, said alignment means including pilot-operated means aboard the aircraft for generating corrective signals upon observation of an offset of the target image from a reference point on said monitoring means, processing means switchable by said selector means to receive said first set of off-aim signals from said target-predesignation means and to translate same into error signals fed to said first servo circuitry in said search mode to slave said second line of sight to said first line of sight, said processing means being switchable by said selector means to receive said second set of off-aim signals from said orientation means and to translate same into instruction signals fed to second servo circuitry in said target-predesignation means in said tracking mode to slave said first line of sight to said second line of sight, and a connection extending from said pilot-operated means to said processing means for supplying said corrective signals thereto, said processing means vectorially combining the received set of off-aim signals with said corrective signals to produce said error signals in said search mode and said instruction signals in said tracking mode, said connection including a non-volatile memory for storing said corrective signals and switch means operable to disconnect said memory from said pilot-operated means upon mutual alignment of said lines of sight whereby the corrective signals thereafter supplied to said processing means have the value required to achieve said mutual alignment.
