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 covari

The ballistic category of atmospheric vehicles includes missiles, launch ve- hicles, and entry capsules. Some missiles and launch vehicles incorporate fi ns as aerodynamic stabilizing and control surfaces. The spacecraft are also catego-
