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.
For lunar spacecraft to have the ability to receive long-distance signals, it needs a large antenna, and from the point of view of spacecraft development and launch, the smaller the antenna, the better, which is a contradiction that cannot be solved for the time being can best question the above conclusion.
