Virtual Fence

Has anybody looked at building DIY virtual fence?

To do what?

The ublox F9P natively supports geofencing of up to 4 round areas. You can upload and configure these with ucenter. One of the GPIO pins is GEOSTAT.

AOG also has an in/out of boundary indicator. I don’t know for sure, but I suspect that it’s in the PGN and available over Ethernet.

Yes pgn 239 to the machine board…
