pretty sure there is a relativistic correction to the GPS clocks.

I believe that the original WAAS repurposed transponders intended for
other L-band satellite signals (e.g. Sirius/XM/LightSquared).
As noted earlier in the discussion, the new satellites might have a
specialized payload, which could have a purpose specific coherent
transponder, rather than a linear translator.
If it is purpose specific and single channel, then making it immune to
the local oscillator is straightforward.
