Solving Lambert problem is the key step in the closed-loop guidance loop. However, only the regular gravitational attraction is considered in the commonly used Lambert algorithm. To further improve the guidance accuracy, an efficient correction strategy is proposed in this paper by introducing a feedback function. The feedback function is derived analytical based on linearization technology with parameters described in the LVLH frame. Different from the classical correction method based on virtual target point, this method is suitable for all kinds of terminal constraint problems. Simulations conducted in this paper have verified the effectiveness and robustness of this modified closed-loop guidance method.
