This script is supposed to run periodically from scheduler and send GPS position data to a server for tracking.
A hardware GPS antenna is required.
Just install the script:
$ScriptInstallUpdate gps-track;
... and create a scheduler:
/ system scheduler add interval=1m name=gps-track on-event="/ system script run gps-track;" start-time=startup;
The configuration goes to global-config-overlay, the only parameter is:
GpsTrackUrl: the url to send json data to
The configured coordinate format (see / system gps) defines the format
sent to the server.
