Regionalized Lunar South Pole Surface Navigation System Analysis
Apollo missions utilized Earth-based assets for navigation because the landings took place at lunar locations in constant view from the Earth. The new exploration campaign to the lunar south pole region will have limited Earth visibility, but the extent to which a navigation system comprised solely...

Apollo missions utilized Earth-based assets for navigation because the landings took place at lunar locations in constant view from the Earth.
