Reusable launch vehicles require fuel-efficient boost-back burns. Existing laws underperform in RTLS missions and lack a theoretical background. This paper proves constant-attitude burn is optimal and offers a predictor-corrector algorithm using null-space optimization. It achieves near-optimal results with minimal computation, providing a robust, real-time guidance solution for diverse missions.
