The US government is working on PNT (position, navigation, and timing), communications, awareness (tracking objects, the beginnings of 'space traffic control' (my term), etc.) and much more via multiple agencies, in order to 'domesticate' (my word) cislunar space, defined as from geosynchronous orbit out past the Moon. The best starting point I know of:
The Artemis program's infrastructure is expected (per some plans, at least) to be the foundation of permanent communication and PNT. The US Space Force is also working on 'Space Situtional Awareness'.
