High performance lunar constellation for navigation services to Moon orbiting users

In order to assist the ever growing number of missions planned to visit the Moon, an international effort is being made to design and commission a communication and navigation lunar constellation of satellites. To this purpose, the goal of this study is to provide first a strategy to help the design of a small-sized lunar constellation, entailing different objectives and users to assist. Then, various optimised constellations are tested including the orbital users’ filtering architectures, extracting insights on the state estimation achievable and its capability to support critical GNC tasks.
