This guidance provides the steering … Webpaper, we study the guidance problem in the entry phase. There are two categories of entry guidance: reference-tracking guidance and predictor–corrector guidance. Shuttle entry guidance (Harpold and Graves, 1979) is the benchmark for reference-tracking guidance. This guidance plans a longitudinal reference in the drag-vs-speed corridor
