> The demo on the show floor was also using eLoran to distribute time from a site in Nevada to the transmitter facility on Black Mountain outside Vegas, showing a way to be fully GPS-independent (though the current eLoran timing was sourced from GPS).
There's been a consistent call by many people that there needs to be a diversity of options for navigation and timing:
Well... and there's the electricity grid which can be used for timing needs accurate enough to a single second, and in Europe there's DCF77 [1] which can not just be used as a 2*10^-12 seconds-accurate timing standard but also a frequency standard.

China has GNSS (BeiDou, plus plans for LEO), plus terrestrial navigation (eLoran), plus a fibre-based network for accurate timing:
