| Popis: | For the development of the optical observation technologies for space debris, Institute of Aerospace Technology (IAT) of JAXA has preliminary constructed an optical observation facility at Nyukasayama mountain in Nagano Prefecture. 35 cm Newtonian optical telescope with 2K2K CCD camera is a main equipment. The telescope is located at an altitude of 1,870 meters. The optical environment of this observation site provides good condition for faint objects detection; 21st magnitude asteroids can be detectable by this small aperture telescope. One of the most important study items in our R& D is to develop an automatic small size GEO debris detection software. In usual case, a long exposure time is necessary to detect faint object by accumulating weak light energy during the time. On the contrary, short exposure observation is necessary for GEO debris detection to avoid the influence of the fixed star streaks image. We have proposed a stacking method for detecting noise level faint GEO debris by accumulating the signals of a number of images, for example, a hundred frames. This paper describes the facility and the developing software. 資料番号: AA0049500040 レポート番号: JAXA-SP-06-006 |
