Hey,
According to wikipedia ( http://en.wikipedia.org/wiki/GPS ), every GPS
satellite carries an atomic clock, providing every receiver on earth
with really precise clock. The radio clock systems you describe are
different and kinda useless when you have GPS onboard.
As an engineer I'm stunned by the level of performance achieved of the
GPS system : the description of Einstein's relativity compensation on
the WP article is really scary :)
