Have you got a Meraki device (like an MX) on something that moves, such as a marine vessel, vehicle, etc?
Then you should check out my latest project. I marry a GPS chip to a raspberry Pi to form a GPS server (using the common gpsd), and then use a script to get the GPS co-ordinates from this to update the Meraki devices location on the overview map.
If you already have a network gpsd on-board then all you need is the script.

For the GNSS people out there - sorry - I know it should be GNSS but the public know the term GPS better.
