Essentially being synced to each other is critical and being sync to
universal time would be an added bonus, which I would like to include, but
not essential.

Do the outlying units have to be synced to universal time or just to each
other? If they just need to be synced to each other then a centrally
broadcast time operating from an RTC should be sufficient and
would eliminate the added complexity of the GPS sync.
