Proceedings of 16th Workshop on JAXA Astrodynamics and Flight Mechanics
For each image obtained during from September 30, to October 26, 2006 (Total 139 images from 1 to 11 km distance), the attitude and position of the spacecraft Hayabusa (MUSES-C: Asteroid Sample-return Spacecraft) are estimated relative to the asteroid Itokawa. By combining these attitudes with those determined in an inertial coordinates by onboard star tracker, the asteroid spin axis direction in the inertial space is determined. Additionally, under the assumption of the spacecraft free flight motion, the spin axis, i.e. the asteroid center of mass, is located in the asteroid coordinate. Using these results the Itokawa shape model is created.
