Definition

A strategy for constructing an LPO communication and navigation constellation in three phases: Phase 1 uses a single NRHO satellite to achieve single coverage of the Earth-Moon transfer critical region; Phase 2 expands to 7 satellites distributed on L1, L2, L4, L5 and NRHO orbits to achieve quadruple coverage of both regions; Phase 3 adds 2 L3 libration point satellites to reach 9 satellites, achieving quadruple coverage across the entire cislunar space.

Application Value

This concept has practical applications in cislunar space science and engineering. Related research supports the planning, implementation, and operations of cislunar missions, forming an integral part of the knowledge system in this field.
