This article discusses a situation where certain FortiGate-40F-3G4G do not report GPS coordinates.
When running the command 'diagnose sys lte-modem gps-info', the output only shows 'GPS daemon enabled: Yes' without displaying latitude and longitude values.
Follow the steps below to verify and isolate the cause of missing GPS coordinates.
Verify GPS configuration: Ensure that the GPS service is enabled:
config system lte-modem
set gps-service enable
end
Confirm GPS daemon status:
Expected working output example:
LTE Modem GPS information:
GPS daemon enabled: Yes
Latitude: 21.0355 N
Longitude: 32.9239 E
UTC fix time: 07:29:35 A,-E
Local fix time: Mon Mar 11 10:29:35 2346
If only the following line is displayed, GPS data is not being received:
Check antenna connection: FortiGate-40F-3G4G uses a passive GPS antenna.
Make sure the GPS antenna is securely connected and positioned with a clear view of the sky. If the FortiGate is installed indoors, move it near a window or outdoors to test satellite reception.
The following are the troubleshooting commands that should be sent if the ticket needs to be opened:
get system status
show full-configuration system lte-modem
diagnose debug crashlog read
diagnose sys lte-modem modem-details
diagnose sys lte-modem sim-nfo
diagnose sys lte-modem signal-info
diagnose sys lte-modem data-session-info
execute lte-modem wireless-profile list
diagnose debug disable
diagnose debug reset
diagnose debug console time enable
diagnose debug app lted -1
diagnose debug duration 0
diagnose debug enable
(After Observed the wwan down).
