One of the most important and complex issues in the field of aerospace engineering is the returning to the atmosphere. Many flying objects do not experience returning to the atmosphere. The study of this topic is relevant only to those flying objects that have left the atmosphere and their return to the atmosphere is important for some reason. Different missions and constraints in the discussion of entering the atmosphere have led to the development of different methods, each of which has its advantages and disadvantages, which is currently one of the current aerospace research scopes. This article introduces the most important atmospheric reentry guidance methods based on trajectory generation. This paper only considers closed-loop guidance methods
