Abstract: The design of guidance system is essential for safe reentry or landing of the spacecraft at the specified region. In this paper, the spacecraft entry models are first summarized. Then, the establishment and difficulty of entry guidance are analyzed, and the research status of spacecraft entry guidance methods is reviewed. The advantages and disadvantages of various entry guidance methods are analyzed. The adaptive predictor-corrector guidance method which has been applied to reentry of China's spacecraft is introduced, which can be used as a general guidance method. Facing the urgent problems needed to be solved for the future development, the importance of fast online feasible trajectories planning is highlighted. The problems needed to be solved for online trajectory planning are analyzed, and possible development directions of spacecraft entry guidance method are also given.

Key words: spacecraft, entry guidance method, predictor-corrector, trajectory planning, general guidance method
