Screening of GEO Objects with Space-based Optical Short Arc Observation

A novel method for screening of GEO objects through space-based optical short arc observations is proposed in this paper.The concepts of measurement attributes and admissible regions are introduced.A plane of admissible region is established to make use of effective short-arc observations,taking the distance of the observer to the target and variation ratio as its axes.Considering the characteristics of GEO objects,the method screens GEO objects through energy constraints and hypothesis of orbit elements.Simulation indicates that the method can screen GEO objects with short arc observations even in cases of lack of accurate information in space objects databases.
