Summary

NAB/trade-show blog notes on Broadcast Positioning System (BPS) tied to ATSC 3.0 / NEXTGEN TV, comparing TV-broadcast timing signals to GPS PPS on a scope (demo claims ~10 ns alignment in the write-up). Positions BPS as a potential terrestrial backup to GNSS for timing-critical infrastructure; includes consumer PPS/TGPIO motherboard teaser.
