4. Set-up a GPS dongle and Time Sync

a. Prepare USB connected GPS device

b. Install the following software:

sudo apt -y install gpsd gpsd-clients python-gps chrony python-gi-cairo

c. Make changes to the gpsd configuration file as follows:

sudo nano /etc/default/gpsd

d. In the file that opens, add or amend lines to make sure the following is present:

START_DAEMON=”true”

USBAUTO=”true”

DEVICES=”/dev/ttyACM0″

GPSD_OPTIONS=”-n”

Hit ctrl-x followed by y to close and save the file.

e. Reboot the Pi and check that the following services are active:

systemctl is-active gpsd

systemctl is-active chronyd

f. Use any of the following three commands to check that the GPS is visible and delivering NMEA words.

cgps – s or

gpsmon -n or

xgps

g. Next, make a change to the chrony configuration file:

sudo nano /etc/chrony/chrony.conf

Add the following line to the end of the file:

refclock SHM 0 offset 0.5 delay 0.2 refid NMEA

Hit ctrl-x followed by y to close and save the file.

h. Check chrony’s sources with the command:

chronyc sources -v

- You will see a list of available time servers plus the GPS source which will be shown as NMEA. Without the network connection, you will just see the NMEA source listed.

Symbols in MS "#*" where # means the GPS is recognized as a local clock, * means that it’s being used to synchronize the Pi system time.

i. use chronyc to provide a more detailed view using the command:

sudo chronyc tracking
