Equilibrium points in Earth-Moon system for continuous communication with far-side station and lunar orbiter

摘要

In order to continuous communication with lunar orbiter and even far side station at the back of Moon, Lagrange points L_1, L_2, L_4 and L_5 is considered to be candidates for relay satellites or orbiters in the Earth-Moon restricted three body system. Positions of Lagrange points in solar system including Earth-Moon system were calculated and missions before and future around these points, especially Sun-Earth L_1 and L_2 were listed. Lagrange points satellites, orbiters and local networks on the ground of a celestial body will constitute a planetary networks connected by an interplanetary backbone in the whole architecture of InterPlaNetary Internet.
