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 There are probably several fatal flaws with this approach. In particular, the following are required: 1) Ability to maintain constant lock to WWV 2) Common-mode error. Will the propagation from WWV be similar enough for all stations to it be a practical common reference. 3) Adequate resolution. Even if, for some reason 1 and 2 are possible, would the result be good enough to use. Like I say, probably completely unworkable, but what are your thoughts?
