In order to land on the moon, some scientists have begun to carry out the verification of lunar navigation  They say that the signals transmitted by GPS satellites in Earth orbit can be received and used on the moon, and the positioning accuracy can reach 200m to 300m
Some researchers believe that lunar navigation can be achieved soon
The most direct and effective way of lunar navigation is for all countries to work together to build a time and space benchmark with positioning and timing functions in the near lunar space, so as to build a set of lunar navigation satellite system
