   I googled around for a bit and it seems that amateur radio satellites   
   are still in orbit and in use.   
      
   See: http://www.qsl.net/w8dro/   
      
   There appear to be many spacecraft available. The only question is   
   whether you can relay through them from a high altitude.   
      
   For positioning GPS may be the go, as others have suggested. You could   
   look at using VHF localisers, still in use for aviation around the   
   world.
