It is actually quite easy. You measure the satellite carrier and code phases relative to the output signal of the Cs, collect all the data, wait a couple of weeks until the IGS final product becomes available, then you calculate the frequency and phase difference and steer the Cs accordingly using a control loop with a tau in the order of 3 weeks at minimum (due to the delay in IGS data), rather 10 to 50 weeks. Simple, right? :-) Attila Kinali -- It is upon moral qualities that a society is ultimately founded.
