空间碎片观测精度分析

Observational Accuracy Analysis of Space Debris

文章分别用内符合精度和外符合精度两种精度指标对云南天文台SBG望远镜的观测数据进行判定,确定了其观测精度。得到高轨空间碎片的观测精度约为2″,和低轨空间碎片的观测精度约为7″,并对观测误差的来源作了一些初步的分析。

The SBG telescope at Yunnan Observatory has already had the observational ability of the space debris, and has obtained abundant observational data. The internal fitting accuracy and external fitting accuracy with the observational data obtained by the SBG telescope are introduced in this paper. The observational accuracy of the space debris in high orbit is 2＂ approximately, but the observational accuracy of the space debris in low orbit is 7＂ approximately. Some preliminary analysis of factors of observational error are given.
