Since 2000, observations have been carried out with three telescopes (1 m, 50 cm and 25 cm). Although main targets are GEO objects, the telescopes have the tracking capability for high-speed moving objects at LEO. The accuracy of the positional measurement is about 0.2-0.3 arcsec, which corresponds to the distance of 40 m at GEO. We are also working on research observations of space debris in recently. For example, the figure shows a short-term light curve of a retired satellite. Two light curves were obtained in 2012 and 2014. It shows that the rotation or tumbling status has varied in these two years.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
