How to Use a USB GPS Device (e.g., U-Blox 7/8) on All Juno Devices

This guide shows you how to set up a USB GPS device like the U-Blox 7/8 on any Juno device using auto-gnss-share on Linux.

1. Make Sure the Device Is Detected

Run the following command:

lsusb

You should see an entry similar to this:

Bus 001 Device 008: ID 1546:01a7 U-Blox AG [u-blox 7]

2. Find the Device Path

Check for the serial device path:

ls /dev/ttyACM*

You should see something like:

/dev/ttyACM0

Note: The exact path may vary slightly depending on your system.

3. Install auto-gnss-share

sudo apt install auto-gnss-share

4. Restart the auto-gnss-share Service

sudo systemctl restart auto-gnss-share.service geoclue.service

5. Check Your Location

Open GNOME Maps or any application that uses geolocation. Your device should now detect your position.

Tip: It may take up to 5 minutes to get a GPS fix, especially if it's the first time or you're indoors.
