With the development of China’s lunar exploration project, China will implement manned lunar landing and lunar base construction mission. However, the existing ground-based communication and navigation (C&N) system will not be able to satisfy the needs of users and the accuracy of C&N services between the earth and the moon, as well as lunar surface. By constructing a C&N constellation at the Earth-Moon libration points, it improves the DOP of the navigation mission of Earth-Moon transfer space users. The C&N constellation support the formation of C&N capabilities in the Earth-Moon space and on the moon surface with a small number of satellites. In this paper, the C&N constellation scheme of the Earth-Moon libration point is adopted, which deploys the C&N satellites at the L2 ~ L5 libration points. Aiming at the link planning problem between satellites and users in the constellation, beam scheduling and topology planning strategies are adopted through heuristic algorithms, and theoretical simulation is carried out.
