Abstract:

A device for correcting the flight path of an air to surface missile and ding said missile to a target. A first map of a strip of ground which is transverse to the direction of flight is provided on a rotatable drum along with a second map of a strip of ground which is parallel with the direction of flight. A live image of the ground over which said missile is traveling is projected first through the first map to provide a position fix of the missile in range and azimuth relative to a target and after a correction has been made to the flight path of the missile, the live image of the ground is projected through the second map to provide guidance correction to direct the missile to the target.
