Abstract
In this paper, we propose methods to estimate positions of `HAYABUSA' during the period of the first touchdown on Itokawa in order to visualize the trajectories of `HAYABUSA'. In this period, there are no reliable ephemeris data of `HAYABUSA'. We used a variety of telemetry data and a shape model of Itokawa to estimate the trajectories. The period is divided into several sub-periods according to the availability of the data. In each sub-period, we propose suitable methods to estimate the positions. The methods are based on the policy that the trajectory should be smooth and continuous in each sub-period.
