摘　　要：基于中国科学院国家天文台空间碎片试验望远镜,联合“仰望一号”“吉林一号”卫星,设计并开展了近地小行星天地基协同监测试验,利用图像处理和定轨方法,实现了天地基观测图像的目标检测和天文定位,完成了近地小行星轨道的精确确定。经分析,基于现有的天地基设备可实现对近地小行星的协同监测和轨道编目,为研判近地小行星撞击风险提供轨道数据支持。Based on the Space Debris Experiment Telescope of the National Astronomical Observatories of the Chinese Academy of Sciences,together with the Yangwang-1 and Jilin-1 satellites,a space-based and ground-based collaborative monitoring experiment for near-Earth asteroids was designed and carried out.By using image processing and orbit determination methods,target detection and astronomical positioning of observation images were realized,and the orbit of near-Earth asteroids was precisely determined.Based on the analysis,the existing equipment can realize space-ground collaborative monitoring and orbit cataloging of near-Earth asteroids,and provide orbital data support for the study and estimating of impact risk of near-Earth asteroids.
