Improving a Nonoptimal Impulsive Trajectory
View through CrossRef
Improving a nonoptimal trajectory is analysed, including adding terminal coasts and midcourse impulses in fixed-time trajectories. Orbit transfer is also analysed. If the primer vector evaluated along an impulsive trajectory fails to satisfy the necessary conditions (NC) for an optimal solution, the way in which the NC are violated provides information that can lead to a solution that does satisfy the NC. The necessary gradients were first derived by Lion and Handelsman.
