Over really long distances the time inaccuracy makes less difference so indeed a phone can do interesting things. I’m a person that likes extremes so the extremely accurate clock time I could get with a GPS synched Oi really appeals to me. Although it’s not really necessary I want to get an rtk GNSS next year to experiment with. Together with ultrasonic microphones I’m pretty sure it could do a great job localizing bats.

Some ham radio friends pointed out that the easy way to synchronize is to relay the sound over a cheap analog radio.

  In my country the public radio broadcasts a time signal every hour just before the news - three beeps and one long beep for the 00 of the next hour.

    Quite possibly just simple ntp may work as well. The radio signals are intended I assume for human hearing.
