Improvements to Optical Track Association with the Direct Bayesian Admissible Region Method

摘要

The direct Bayesian admissible region approach is. an a priori state free measurement association and initial orbit determination technique. When this approach was initially applied to tracklets from a survey of geostationary objects taken at the Zimmerwald Observatory of the Astronomical Institute of the University of Bern, difficulties with both false associations and missed associations were encountered. In this paper, ideas to improve the association of tracklets are proposed and analyzed. It aims to close the loop on the short-arc optical track association problem by enhancing the survey strategy based on the association results and vice versa.
