Preliminary Orbit Determination for GEO Objects Using Space-Based Optical Observations

Abstract:

Preliminary orbit determination for geosynchronous Earth orbit (GEO) using two short arcs of space-based optical observations plays a key role in the space-based space surveillance systems. The concept of attributable is introduced to represent the information in a short arc of observations. Using two-body integrals, the polynomial equations for distance and radial velocity between the surveillance satellite and the GEO object at two epochs are constructed. By variables transformation, multiple solutions of these equations are obtained. By covariance analysis, a penalty function is given to select the practical solutions for computing preliminary orbits. The simulation results show this algorithm can successfully obtain preliminary orbits with certain accuracy.
