The dynamics of orbit uncertainty in an unstable orbital environment are discussed with specific application to the orbit determination of a halo orbit about the Earth{Sun L1 point. This article documents a simplified orbit determination covariance program developed under Telecommunications and Mission Operations Division Technology support. The program is ideally suited to investigate spacecraft trajectory navigation in challenging environments, where the basic dynamics of the trajectory can no longer be modeled using near-Keplerian motion.
