    Brooke-
     
     I'd call that semantics. You may no longer need one physically installed in 
    your nav station, but when any one of us uses the GPS system we do indeed 
    need atomic clocks--plural. The typical GPS user is using 9-16 atomic clocks 
    at all times, three or four of them on each of three or four satellites being 
    used for the GPS to get a fix.
    
     Much more economical to put a couple of hundred atomic clocks in orbit, than 
    to deploy one to each ship or user. Clever of them gummint boys.
