Microsecond Accurate NTP using PPS signals from a $12 GPS
In this video I demonstrate how to set up this $12 GPS as a microsecond accurate network time protocol (NTP) source driving Chrony via a Raspberry Pi fed by a GPS pulse per second (PPS) signal. This will allow your home and all connected devices to utilize a very accurate time source for precise time synchronization.
