How wide is the PPS?  If it's tiny (10 microseconds) some serial port setups 
won't catch it.  If so, a one-shot pulse stretcher would be handy.

Does the PPS signal stop ticking when it runs out of satellites?  If so, I 
think you can use the other one-shot in the package so that the LED is on 
when the PPS is ticking and blinks when the PPS is off. and is off if there 
is no power).
