Abstract: As a significant component of the cislunar space infrastructure（CSI），lunar surface communication and navigation infrastructure（LSCNI） provides more convenient communication networking services for the surface local users within hotspot areas，and also provides reference of surface local positioning and navigation as well as certain positioning，navigation and timing（PNT） capacities.On the basis of trend analysis，overall architectures of lunar surface communication and navigation infrastructure are proposed focusing on the medium and long-term strategic development of current major projects as well as future large-scale lunar activities.The architectures contain the network architecture and the lunar surface-space interfaces.Then，the solutions to some core issues such as lunar frequency planning，radio wave channel modeling，network access，high-speed transmissions，positioning and navigation methods are analyzed.Finally，suggestions for phased construction and technological development roadmap are proposed，providing reference for the planning and construction of communication and navigation systems for future lunar exploration missions.
