中文摘要：

利用内符合精度和外符合精度两种精度判定方法,对国内首台基于APOSOS亚太地基光学空间物体观测系统）项目安装在国外的15 cm地基空间碎片光电观测望远镜获得的观测数据进行了观测精度计算分析。经过计算分析,得到内符合精度在5″左右;利用全球激光测距服务系统提供的综合激光测距数据格式标准点资料对Lageos1、Lageos2和Ajisai卫星进行精密定轨,进而获得这些卫星的精密轨道,并以此精密轨道作为APOSOS 15 cm光电望远镜观测数据外符合精度的评定依据,得到外符合精度大约在6″左右。计算分析结果表明：系统的观测精度较高,达到了设计指标,能够满足科研和工程应用的需要。

英文摘要：

Based on APOSOS（asia-pacific ground-based optical space observation system） project, the first 15 cm ground-based space debris photo-electric telescope manufactured by China was firstly installed abroad and obtained much observational data. The paper calculated and analyzed the observational accuracy of observational data using two accuracy estimation criterion-internal fitting accuracy and external fitting accuracy estimation, and the result of internal fitting accuracy is on 5 arc seconds; then, obtained precise orbit of satellite Lageos1, Lageos2 and Ajisai derived from precise orbit determination which made use of satellite laser ranging normal point data from International Laser Ranging Service（ILRS）, and the analysis of external fitting accuracy was based on the precise orbit, the result of external fitting accuracy was around 6 arc seconds. All the results indicate that APOSOS 15 cm opto-electric telescope has relatively high observational accuracy and reaches the design specification,which can satisfy the demands for science and engineering application.
