Guidance with traditional trajectory correction scheme usually starts from the trajectory apex time to reduce drag penalties early\nin flight; however, this method cannot get the max trajectory correction capability of canards according to our analysis. This paper\npresents an optimized trajectory correction scheme by taking different control phases of canards in ballistic ascending segment and\nballistic descending segment. Simulation indicates that the optimized trajectory correction can improve the trajectory correction\ncapability greatly. The result of an example trajectory and Monte Carlo simulations with the predictive guidance law and the\ntrajectory tracking guidance law testifies the effectiveness of the optimized trajectory correction scheme.
