> if there's enough sky visibility

Which is a thing we shouldn't be requiring here. Picking up a single satellite without any position data is enough to drive a clock.

You need enough sky visibility to discern signal from a single satellite from the background noise without having accurate time and recent enough almanac already.

That 'three words' grid-hex system seems a lot cheaper and doesn't rely on time-space constraints in this light
