N2 - This paper presents a gravity-turn-based precise landing guidance algorithm for reusable rockets with the consideration of aerodynamic drag and necessary path constraints for operation safety. First, a gravity-turn trajectory is found to make the rocket have a soft landing. Then, to eliminate the downrange and crossrange errors, which is required by precise landing, we propose to solve an optimal control problem to correct the thrust acceleration associated with the gravity-turn trajectory. In the end, we can design an algorithm requiring only solving a one-parameter root-finding problem and a small-scale linear programming problem. Numerical examples are provided to demonstrate the performance of the guidance algorithm.
