A NEW APPROACH FOR RE-ENTRY VEHICLE TRAJECTORY PLANNING AND GUIDANCE

摘要

A new approach based on path constraint control is proposed in this paper for re-entry vehicle trajectory planning and guidance. A unified formula has been obtained which reveals the inherent characteristic of path constraints in r-V plane. And an analytical trajectory planning method with fewer parameters is developed. Dynamic inverse guidance law is designed to tracking the reference trajectory. Simulation results verify the feasibility of the approach.
