The principles of global navigation of spacecrafts on the surface of the Moon

The Roskosmos Agency discusses an opportunity to create a global positioning system for the Moon as analogue of well-done system GLONASS. On the other hand, there is conception of selenographic coordinates system based on artificial point-like signs, which are optical beacons. The system may be made on observations with a single artificial lunar satellite (ALS) on polar orbit. The ALS must be equipped with a high accuracy stellar orientation system and a panoramic camera for picturing the lunar surface. These devices are built-in in all ALS, and an implementation of the conception will not require any correction to the ALS projects. It is expected that as a result of the realization of missions of "Luna-Glob" and "Luna-Resurs" an accuracy of navigation will be attained on Moon at the level of few meters. On this basis, a global navigation system for Moon can include only on one polar ALS and two spacecrafts in Lagrange points L 1 and L 2 of the system "Earth-Moon".
