Big fan of Geerling, precisely because he goes down these obscure rabbit holes. Found out about Meshtastic through him, and now BPS.
There are lots of applications to having a super-accurate time source, without having to have antennas and view of multiple satellites.
Synchronizing time is tricky. WWVB is too coarse resolution. NNTP requires access to the internet and all the inherent lags and delays. GPS was the only accurate source, but the super high resolution time signal is classified, and you are at the mercy of view of the sky. Also, signal jamming, thanks to what's going on in Europe and Ukraine.
BPS could be a niche experiment, or a Big Deal.
Even having a semi-decent fallback from GPS time signals is a Big Deal.
