I love these incredibly simple and elegant classic technologies. GPS is one of the best. It seems like it would be incredibly complicated and mysterious, but it's actually quite straightforward.

I'm working on a presentation now to explain how GPS works to second graders. If they understand it, I'll take some photos and do a write-up.
