Meshtastic GPS

[Albert Margolis]

I just got one of these tracker / transceivers to play with.

One of its interesting characteristics is that it seems to get a solid gps lock indoors. Much faster than the typical robotics sensors I have used. Has anyone used one of these on a robot?

Without looking too hard (assuming, there is a understandable serial
protocol of the GNSS data;-), I would go to the bare GNSS module directly:

That's all a robot would need;-)

But while most newer modules report a fix even indoors, you won't get
very good accuracy. There is simply too much interference &
multi-path-ing going on:-(

L1 + L5 receivers are a bit better, but don't expect to navigate indoors
based on GNSS. You might get 'the room' +/-1 right, but not much better
consistently.

Have fun;-)
