Answer 1

GPS involves receiving and amplifying tiny microwave signals from satellites, decoding them and identifying the satellites, comparing the signals from them, and finding your postion from the analysis. Obviously, it's possible for you to make a GPS, since other humans had to make the first ones, but ti sounds pretty serious. Try the links on this page:

I didn't find much else on this, but you might try looking though Bowden's links to see if there are any there:
