Autonomous navigation methods for spacecraft formation flying in cislunar space

Abstract. Due to the increasing number of deep space missions in following years, focus on methods and strategies that enable a spacecraft perform critical operations autonomously is becoming crucial. In context cislunar space, this research aims investigate state estimation for such highly nonlinear dynamics environment order identify best operational scenarios constraints accurate performance autonomous navigation. particular, LiAISON navigation method considered formation satellites moving exploiting presence other cooperative exchange inter-satellite signals get range measurements.
