Maybe? It'd probably harder than you think: https://www.youtube.com/watch?v=BVxOb8-d7Ic

I think that is the whole point of bringing wikipedia along. Pretty sure you could reconstruct most of civilization from it...

Not sure, it's high on modern theoretical content but not very on low-tech practicals, e.g. no information on how to go about prospecting for copper or iron.

You won't need to prospect for iron or copper if civilization collapsed, the fact of the matter is we could never be "bombed back to the stone age" as there is soooo much processed iron just lying around - everywhere.

We just need technicals on recycling and smelting, cooling, rolling, machining, etc.

Myself and a couple other guys did the due-dillegence for a proposed documentary about Stone Age to building a functional electric calculator.

The starting point would have various ores as they came from the Earth.

Glass and metal working are key.

Or your cached copy of OpenStreetMap to find your way around.

Hopefully the satellites will continue to operate for GPS. Could it be possible to approximate gps with ground radio stations (cell phones)?

GPS relies (heavily) on the satellites knowing their own orbits, which they get from a ground station, which means the satellites would very quickly get very inaccurate (and GPS with 200km accuracy is somewhat useless).
