Image-based navigation and guidance of spacecraft


Accurate and safe landing is required for future lunar and planetary exploration. Our laboratory studies image-based navigation which uses pattern matching between terrain map of the surface and onboard camera images. In Hayabusa project, operator-based landmark navigation system on ground could help the spacecraft to land on the safe area of asteroid Itokawa. In near future lunar exploration, the system will be installed in onboard computer and spacecraft performs landmark navigation autonomously. Moreover, we study autonomous hazard detection and avoidance for safe landing.
