ABSTRACT:
A method for compensating for pre-reentry errors generated by the weapon ivery system to provide a reduced impact range error dispersion over that provided by a ballistic trajectory after reentry comprising maneuvering the reentry body after reentry so that the terminal flight direction is essentially in line with the line of means of the reentry body's position-error ellipse that exists just prior to reentry. The reentry body trajectory follows a sequence of a ballistic leg from reentry, a dive maneuver including an optional pullup leg and a pulldown leg to establish the required terminal direction, and a terminal ballistic leg to impact. The required maneuvering is accomplished by modulating the aerodynamic lift of the reentry body by controlling the reentry body's roll orientation.
