OK, stop me if this is really stupid. The initial site is in Colorado.
Would it be possible to use WWV? In particular:
1) Lock a reference to the carrier of one of the WWV signals
2) Generate PPS off of WWV-locked reference
3) Periodically send difference of GPSDO PPS and WWV-locked PPS home,
along with GPS lock indication
4) When GPS goes away do the math at home and correct for the timing drift
of the GPSDO compared to WWV-locked reference
I don't think a received WWV (or WWVB) signal is stable to 30ns...
