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.
