I cannot retrieve any GNSS data, whereas I’m in open air. #

Please make sure that you plugged a male antenna into the port 5 on the side of ZED Box. Then reboot, and run cgps.

gpsd has know incompatibilities when working with systemd, which is the default behavior. For that reason, we strongly advise you NOT to use gpsd with systemd. Usual trouble are that your host will need to reboot every time you want to stop your application and run it again.

The easiest way to run gpsd is with

sudo gpsd -nG -P /run/ /dev/ttyACM0

You can run this in a CRON job :

@reboot sleep 10 && /usr/sbin/gpsd -nG -P /run/ /dev/ttyACM0
