GPS-Disciplined NTP Server on Raspberry Pi 4

GPS-Disciplined NTP Server on Raspberry Pi 4 Hi guys, In this video I'll explain how to install a GPS USB module to get precise time and date information from GNSS (GPS, GALILEO, GLONASS, BEIDO) satellite constelations to provide it to our local network servers, workstations and/or other gadgets and appliances. Check more about GNSS constelations at ESA space agency webpage. Check link below: https://www.gsa.europa.eu/european-gn... I'll be using a GPS usb receiver you can get from ALIEXPRESS. Check link below: https://www.aliexpress.com/item/32969... The main computer hardware on the video was a Raspberry Pi 4 with Raspberry Pi OS. The main commands on Linux prompt were: apt install gpsd apt install gpsd-clients cd /etc/deafult nano gpsd [EDIT] START_DAEMON="true" USBAUTO="true" DEVICES=#/dev/ttyACM0" GPSD_OPTIONS="-n -D 1" ENABLED="yes" GPS_BAUD=9600 [END_OF_EDIT] systemctl restart gpsd systemctl status gpsd systemctl stop gpsd #Tools to check gps raw data: gpsmon /dev/ttyCM0 cgps -d apt install ntp cd /etc/ nano ntp.conf [EDIT] server 127.127.28.0 minpoll 3 maxpoll 3 fudge 127.127.28.0 refid GPS pool 0.debian.poool.ntp.org iburst [END_OF_EDIT] systemctl restart ntp #NTP monitoring: ntpq -p ufw allow 123 ufw enable I hope you enjoyed this video.
