Abstract

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.
