Symptoms
Inaccurate GPS
Latitude Rugged Systems using the 2.30 or higher U-Blox sensor driver will receive inaccurate GPS data.
This happens because the U-Blox sensor driver sends specific messages that are not being read correctly. This causes some software applications using the GPS COM port to not see the connection correctly.
Note: This applies to all Rugged Latitude Systems that shipped with a U-Blox module, except the Rugged Latitude 7202.
Resolution
To fix this behavior, the U-Blox driver version 2.30 or higher needs to be uninstalled and replaced with either the U-Blox version 2.24 (On the Dell Support site for Windows 7 & Windows 10) or rolled back to the "USB serial device" driver (Windows 10 only).
Note: Any persistent failures after rolling back the driver will not have further support by U-Blox.
