Atomic clocks are not precise enough, they need nuclear clocks, which are not developed yet: https://thoriumclock.eu/ https://thoriumclock.eu/

  GPS uses atomic clocks, not sure why we'd need something more precise for a timing reference on any other satellite system, unless you wanted to get like millimeter-level accuracy using nothing but satellites (and that would require a lot more than just a better clock on the sats).

    The clocks aren’t even the biggest source of error in the pseudo ranges.

    With nuclear clocks, GPS will be unnecessary.
