据外电报道:在1981年4月的航天飞机处女航行中,航宇局为了确保首次飞行万无一失,要求动用空军的“绝密级”高分辨力望远镜跟踪相机来拍摄航天飞机腹部防热瓦的照片。至于是否拍摄了照片,人们不得而知。但这座绝密级的跟踪站到底是一座什么样的地面跟踪系统?它有哪些性能?人们作了不少的猜测。现将有关内容摘译如下。一、系统概述如何对轨道高度达四万公里的空间物体及时发现、观测和轨道状态的判断,已经成为空间监视和空间目标鉴别的有关机构的一
According to a foreign report: In April 1981, the space shuttle virgin mission, the NASA in order to ensure that the first flight foolproof, requiring the use of the Air Force’s “top secret” high resolution telescope to track the camera to take photos of the abdomen of the solar thermal tile. As to whether the photo was taken, people do not know. However, this top-class tracking station in the end is what kind of ground tracking system? What are its performance? People made a lot of speculation. The relevant content is now extracted as follows. I. System Overview How to detect, observe and determine the orbital state of space objects with a height of 40,000 km or so has become one of the relevant agencies for space surveillance and identification of space targets
