Operating in the highly dynamic Earth-Moon libration point orbit (LPO) region,which is predominantly perturbed by the Earth, the Moon, and the Sun, isa challenge. The Artemis mission operated by the NASA Goddard Space FlightCenter and the University of California at Berkeley recently became the first toever maintain orbits in this regime. The resulting operational data provides significantopportunity for analysis to better understand these orbits and their operationalconstraints. Future efforts to quantify orbit determination results, recoverun-modeled accelerations, realistic uncertainty propagation, and ultimatelyLPO utilization will grow out of an ability to post-process this operationaldata for further understanding of the dynamics involved. To prepare forpost-processing of this data, this paper quantifies the effects of various contributorsto the dynamic models, experimentally models errors in a simulated environment,and outlines areas of future focus. Realistic spacecraft ephemerisand attribute information will be used to the maximum extent possible. Simulationsof orbit determination efficacy are performed using the Analytical GraphicsInc. Orbit Determination Tool Kit (ODTK) with appropriate tracking andspacecraft characteristics and known error sources.
