Coordinatization Effects on Non-Gaussian Uncertainty for Track Initialization and Refinement

Abstract

A comparison between common coordinate systems used for state representation in orbital mechanics is presented for track initialization in orbit determination and follow-on tracking utilizing optical angles-only measurements. A Gaussian mixture parameterized probability density function representing uniform uncertainty across all possible Earth-bound constrained orbits is constructed. This distribution is mapped into each coordinate system, propagated forward in time, and refined via a Bayesian filter. Performance measures related to uncertainty characterization are applied to judge the efficacy of the method in each coordinate system.
