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.
