Hey, here is some info regarding non-GPS based guidance. Firstly I would guess you have already read the info in the arducopter wiki but in case you missed it there are four methods listed there.
1 - http://ardupilot.org/copter/docs/common-pozyx.html
2 - http://ardupilot.org/copter/docs/common-optitrack.html
3 - http://ardupilot.org/copter/docs/common-vio-tracking-camera.html
4 - http://ardupilot.org/copter/docs/common-zed.html
There are should be enough info for you to start implementing your chosen method. Also you’ll find links to further info regarding setup for each specific system.
Here is a link to the posxy wiki: https://www.pozyx.io/documentation
which includes setup info, although I would personally focus on the info in the arducopter wiki regarding VIO tracking cameras (link 3 above) as that has a pretty detailed guide to setting up a stereo camrera as a GPS substitute.
Anyway, good luck!
