An Optimal High-altitude Guidance Law for Reentry Vehicle

Chen Hai

Abstract

An optimal guidance law for reentry vehicle with high altitude maneuvering on downward phase is studied.The optimal high altitude guidance law with reentry constraint conditions is derived by using the optimal control theory,and the algorithm of time to go is also given.The numerical simulation shows the feasibility of this guidance law in high altitude maneuvering of reentry vehicle.
