    Re: Measuring time in small boat CN: what devices do yourecommend?

     From everything I've read, actually 3 atomic clocks on the old birds, and 4 
    on the new birds. So "GPS time" will be the result of what one bird has 
    decided three or four atomic clocks really say, and a normal 3D fix that has 
    polled 4 birds will be presenting a time "concurrence" from 12-16 atomic 
    clocks. Which are corrected as needed from ground control, I believe. I think 
    the compensation for leap seconds, etc, is in the signal that is sent, what 
    is it, once every 14 minutes by the satellites?
    
    Not a bad way to access that many million dollars worth of clocks.
