Zusammenfassung:The availability of gun-hardened guidance and control systems has made highly accurate gun-launched rocket-assisted guided projectiles feasible. A composite guidance algorithm is presented for such vehicles. The algorithm is capable of extending range and cross-range capability of the projectile, and allows it to be retargeted after launch. The algorithm also employs model predictive control to control time of flight to allow a salvo of projectiles to arrive simultaneously. The time-of-flight control achieves its objective by trajectory shaping and corrects for winds, off-nominal launch conditions, and rocket motor variations. [PUBLISHER ABSTRACT]
