Even if you have no good GPS system, if you're landing a new, you get  
good terrain maps on the way down. You're going to need them. If you  
don't have that, then you need to play a double blind system with two  
players moving the pieces and telling the two players in the next  
room what and where everything is via a pair of intercoms.

As for navigation. There's still inertial and a host of other cruder  
methods for tracking things. Even if you use ground navigation	
beacons far in your rear for positional data. Think GPS/ ILS and Loran.
