Minimum-Time Orbital Phasing Maneuvers
2003
Journal of Guidance Control and Dynamics
The minimum-time, constant-thrust, orbital phasing maneuver is studied numerically. Non-dimensionalization reduces the problem to one where thrust magnitude and phase angle are the only parameters. Extremal solutions are obtained for the entire range of practical values of thrust magnitude and phase angle. Plots of trajectories, thrust profiles, and loci of initial costates are used to identify a near-invariance principle that leads to a variety of conclusions about this class of problems. The
