The rendezvous and landing missions are very significant for scientific explorations. In such missions, the navigation and guidance based on image data is very important. The spacecraft Hayabusa performed the descent flights to the target asteroid Itokawa in November of 2005. To accurately determine the spacecraft position, a landmark tracking scheme with(More)
Introduction: A telescopic camera on Hayabusa, AMICA (Asteroid Multiband Imaging Camera)[1] brought about 1400 images, 1GB. A part of AMICA science team and GNC team (Guidance and Navigation Control) have made a task team of shape modeling. This team gave two versions for pole orientation and Itokawa's shape on the basis of AMICA images. One is an interim(More)
The locations of the pole and rotation axis of asteroid 25143 Itokawa were derived from Asteroid Multiband Imaging Camera data on the Hayabusa spacecraft. The retrograde pole orientation had a right ascension of 90.53 degrees and a declination of -66.30 degrees (52000 equinox) or equivalently 128.5 degrees and -89.66 degrees in ecliptic coordinates with a(More)
