A lateral guidance method is presented to satisfied long lateral maneuver range for reentry vehicle. The conventional technique for lateral guidance is based on reference trajectory, and the bank sign is determined by the relative position from destination area. A new automated guidance method of lateral maneuver is given based on coverage zone profile, which steers the vehicle to destination without reference trajectory. Database of possible flight paths are calculated off line, the bank angle is related to lateral and longitudinal range. The guidance law predicts position at restrained terminal velocity with different bank angles, and determines one with minimum distance from destination. Simulation in nominal case indicates that lateral maneuver range over half of longitudinal range can be satisfied. Monte Carlo simulations are taken for aerodynamic dispersions. The lateral guidance method is proved with good interference capacity, and taps the potential of lateral maneuver capability by reaching target beyond nominal range.
