This study evaluates the potential observability benefits of space-based passive RF systems compared to other ground-based and space-based observers for cislunar Space Domain Awareness. TDoA and FDoA observations are used for orbit determination of objects in the lunar vicinity using observers in GEO and XGEO. The results are compared to ground-based observations in order to analyze the performance gains over existing architectures. Results show using space-based systems result in faster filter convergence and more accurate state estimates.
