This paper analyzes orbit families for the mission of space-based cislunar domain awareness and evaluates a novel set of metrics that can be used to inform the specific orbit parameterization for cislunar SDA constellation design. We present a dynamic simulation of the cislunar environment for use in numerical analysis of various pairings of resident space objects and sensing satellites intended for cislunar space domain awareness. Then we apply numerical observability analysis to calculate the local estimation condition number of observations of satellites on trajectories in the Earth-Moon system. Using our catalogue of simulated cislunar orbits as well as our heuristic and empirical metrics, we describe which orbit families provide the best observability of other cislunar orbit families and suggest a method for architecting constellations of observers in different cislunar orbits to perform the general cislunar space domain awareness mission.
