Raspberry Pi GPS Time Sync | Raspberry Pi Field Computer

Hello Operators
Continuing on with our Raspberry Pi field computer series, in todays video we're setting up raspberry pi gps time sync, for off grid raspberry pi projects or off grid commuications using a raspberry pi. For my project, my softare running on the raspberry pi, requires and accurate clock. Normally that would come from and NTP server when connected t the internet. When we don't have the internet, we need to find some other way to sync the raspberry pi clock, so that our communications applications JS8Call, WSPR and FT8, no when to start and when to stop.

I'll be running a Raspberry Pi 3B+ running Raspberry Pi Stretch, using a cheap USB GPS Dongle from Amazon. Although this tutorial can be used for many different applications. Mine is off grid communications eg ham radio with a rspberry pi.

Normally the time the comes from an ntp server on the internet. When I'm in a remote location operating from the field station, often there are no internet connections available. Naturally GPS coverage is available, so we can update the system click or the real-time clock if you have one.

I found a tutorial from Mike Richards entitled "Raspberry Pi Stretch – GPS Dongle as a time source with Chrony & Timedatectl" https://photobyte.org/raspberry-pi-stretch-gps-dongle-as-a-time-source-with-chrony-timedatectl/
You can find the complete instructions on Mikes website.

Enjoy the world of IOT the Internet of things.
