In this research a perturbation based guidance method is developed for non-Keplerian problem. Problem is linearized in the presence non-gravitational forces like aerodynamic, so it can improve the performance of C* guidance for reentry problems. In this study developed method is used for a reentry guidance accuracy and performance. Results showed significant increases in accuracy compared to Keplerian approaches.
