Replying to my own last post!
If we had homemade sextants, watches and basic self generated sun dec and EOT tables, + home made reflector telescope and Jupiter moon tables (for correcting the watch on land in distant parts), then we would have nearly a "self contained" cel nav system.
I say "nearly", because we would still need accurate charts, without which, knowing lat and long is a bit pointless.
I've no idea how you could have good worldwide accurate charts without the cast of hundreds/thousands you have already hinted at.
So for me, it is the charts that are the impossible thing for the lone navigator to be truely "self sufficient".
Still good fun.
