Or you could add a radio transmitter to each of the clocks in lower, almost 
circular orbits, and then use the differences between the times recieved from 
multiple orbiting atomic clocks to pinpoint your locations. You'd need a lot 
of them, though, probably something like 24 clocks in 3 orbital planes. OK, 
maybe you could get by with 21, if you beleived you don't need any spares.

But naah, that would never work ;>.
