No position fix
TroubleshootingGNSSGPS The router’s GNSS fix details and settings can be accessed from the GNSS page of the router’s web interface: .
Antenna connection problem — Ensure that the supplied smart antenna is connected in accordance with the instructions provided. A GNSS position fix will not be possible if the antenna is not connected or the antenna cables are connected incorrectly.
Internal GNSS receiver disabled — Unless your system uses a different source for GNSS position data (e.g.: an external GNSS receiver) then the router’s GNSS receiver should be enabled. The router’s internal GNSS can be enabled and disabled from the web interface GNSS page.
External GNSS receiver fault — If you are using an external GNSS receiver for position data then ensure it is connected and working correctly. Refer to the troubleshooting guidance provided in your external GNSS receiver’s documentation.
Antenna installation location — GNSS antennas require a clear line of sight to the sky. Check that your antenna is installed in accordance with the antenna location requirements and that there are no obstructions obscuring the antenna's line of sight or no other devices causing interference.
Damaged or insecure cabling — Check that connectors are fully inserted into the unit and locked in position. Check cabling and connectors for signs of damage or corrosion, replace if necessary.
Geographic location or prevailing conditions — Some geographic location and prevailing weather conditions can prevent a position fix. Check to see if a position fix can be obtained in a different geographic location or under better weather conditions.
