Clock modules get timing from GPS, GLONASS and BeiDou

NEO-M8T and LEA-M8T are precision timing modules from u-blox, that work concurrently from GPS, GLONASS and BeiDou, and are Galileo-ready. Accuracy is said to be within 20ns and the receivers autonomously cold start on a -148dBm signal or, when aided (see below), -157dBm (GPS and GLONASS…
