Abstract

Multiple hypothesis tracking methods are under development for space surveillance and one challenge is the accurate and timely orbit initiation from sets of uncorrelated optical observations. This paper develops gating methods for correlation of optical observations in space surveillance. A pair gate based on the concept of an admissible region is introduced. By implementing a hierarchy from fast, but coarse, to more expensive, but accurate gates, the number of hypotheses to be considered for initial orbit determination is reduced considerably. Simulation results demonstrate the effectiveness of the gating procedure, address gate parameter determination, and study the accuracy of initial orbits.
