Loran or GPS, and I guess they will after them, too.

 >> I used to be able to tell the time by observing Polaris and the  
pointers to within fifteen minutes accuracy at any time of year. I  
forget the trick now, but it's fairly easy with a little mental  
arithmetic. Doh! That's today's kids sunk, then.

 >> I've never been south of the equator, but I believe that there  
are very few bright stars or constellations visible down under. On  
the other hand, the Magellanic clouds probably make up for it a bit.
