Only as good as the oscillator.

I need an analog waveform that encodes the date and time to within the resolution needed.

We assume the existence of terrestrial and celestial radio sources with a band of interest between 0.1 and 1000 Megahertz.

We assume that all radio sources, modulation of phase, frequency, or amplitude is possible according to  signal(A,w,p) = A sin(wt + p).

For a single radio source located anywhere, what is the greatest difference in time of arrival possible.

For a single receiver, no difference in time of arrival is possible. (draw this)

To build up this capability in a modular and reuseable fashion we wish to design and produce a frequency generator with the following specifications.

1) GPS disciplined
2) 

Two such frequency generators must be synchronized to within 20 nanoseconds.

Adjustment must be possible to improve synchronization over long running times to account for drift, systematic and random errors.
