Good morning, there are reliable solutions with a GPS module, the <<NTP Time Server Monitor>> software and the file configuration <<ntp-4.2.8p15-v2 >> from Meinberg on a recent PC. Just copy these few lines into the NTP configuration file here:
# Add GPS clock server 127.127.20.3 minpoll 4 maxpoll 4 mode 16 prefer fudge 127.127.20.3 refid gGPS time2 0.1275 # Add PPS driver server 127.127.22.3 minpoll 4 maxpoll 4 fudge 127.127.22.3 time1 0.004 refid kPPS
Accuracy is +/- 1ms With this method your PC is on very precise time after 5 minutes, no need to wait like other software 30 minutes to 1 hour..
Your module generates a COM port number that must be entered in NTP(configuration) from the start of the configuration just below the country. Ex: 127.127.20.(com port number)
If you have any questions..
