美国国家航空航天局(NASA)一直在使用电荷耦合装置(CCD)碎片望远镜(CDT),这是一个位于NM Cloudcroft附近的可移动32厘米施密特望远镜,以帮助表征地球同步轨道(GEO)中的碎片环境[1,2]。CDT系统能够在20秒内检测到17等的物体,这相当于一个直径0.6米,反照率0.20的物体在36000公里处。描述的是1998年420小时观测季节的结果。不相关靶标(UCTs)与相关靶标(CTs)的比例与前人的研究一致。
The National Aeronautics and Space Administration (NASA) has been using the Charged Coupled Device (CCD) Debris Telescope (CDT), a transportable 32-cm Schmidt telescope located near Cloudcroft, NM, to help characterize the debris environment in Geosynchronous Earth Orbit (GEO) [1,2]. The CDT system is capable of detecting 17 magnitude objects in a 20 second integration which corresponds to a ~0.6-meter diameter, 0.20 albedo object at 36,000 km. Described are the results of the viewing season for 1998, ~420 hours. The proportion of Uncorrelated Targets (UCTs) to Correlated Targets (CTs) is in agreement with previous studies.
