  Recent advances in space technology provide an opportunity for small
satellites to be launched in cislunar space. However, tracking these small
satellites still depends on ground-based operations. Autonomous navigation
could be a possible solution considering challenges presented by costly ground
operations and limited onboard power available for small satellites. There have
been various studies on autonomous navigation methods for cislunar missions.
One of them, LiAISON, provides an autonomous orbit determination solution
solely using inter-satellite measurements. This study aims at providing a
detailed performance analysis of crosslink radiometric measurements based on
autonomous orbit determination for cislunar small satellite formations
considering the effects of measurement type, measurement accuracy, bias,
formation geometry, and network topology. This study shows that range
observations provide better state estimation accuracy than range-rate
observations for the autonomous navigation system in cislunar space.
Line-of-sight angle measurements derived from radiometric measurements do not
improve the overall system performance. In addition, less precise crosslink
measurement methods could be an option for formations in the high observable
orbital configurations. It was found that measurement biases and measurements
with high intervals reduce the overall system performance. In case there are
more than two spacecraft in the formation, the navigation system in the mesh
topology provided better overall state estimation than the centralized
topology.
