Abstract

What Hayabusa demonstrated was, first of all, a pin-point landing whose size is just 20 to 30 meters in radius. This required an extraordinary accurate orbit estimation during the descent, since just one centimeter per sec dispersion may have resulted in 36 meters in one hour. And the flight needed almost Worms' speed control and management. What contributed to this was in the landmark tracking navigation. Conventional landmark tracking took a lot of time. But the Hayabusa project team developed a new tool that combines human's assist with the computer aided terminal display. A real-time landmark navigation did contribute to the successful precise navigation to the specified area on the surface. This paper presents the essence of it.
