RFID/GPS tracking

Anyone used GPS or RFID to track objects within a space, I don’t need mm accuracy, +/- 50-100cm would probably be fine, within a space (outside) in a radius of approx 25m
Any suggestions or success stories gratefully received :)

haven’t tried this myself but stumbled upon this recently:

comes with code for the arduino:

That looks good! I’ll try and check it out…

hi catweasel,

any updates on that? i’m curious…

The project got postponed, and I dont have the budget to get a kit to test just yet, but it did look like it should do the job, so if it happens eventually I will check it out!

I use Pozyx system which is pretty accurate !
