The U.S. satellite system, AFAIK, is not guaranteed for high accuracy to civilians and also is vulnerable to foreign interference/destruction. Perhaps while we have it as it is now, it might be prudent to accurately track the EFC voltage over time that one needs to maintain a particular oscillator to it maximum stability. Then make an independent oscillator and divider chain that will cycle a digital potentiometer taps or perhaps a DAC to automatically maintain the rate-of - change needed to keep said oscillator at maximum stability. Doing this now with at least one or two oscillators and then comparing to a GPS derived frequency and least gives one a “belt and suspender” back-up. High quality 10 MHz oscillators are available all day on epay for less than $50. Or one could splurge on a HP 10811 or Rubidium for less than $100. Just food for thought.
