Direct-Shooting

Definition

A direct optimization method in trajectory optimization that discretizes the continuous control problem and iteratively searches for control parameters satisfying boundary constraints. The paper uses direct-shooting to optimize the total velocity increment of impulsive transfer trajectories, with tangential constraints connecting the LEO parking orbit and target DRO, solving for optimal two-impulse and three-impulse transfer parameters.
