Don't worry about the GPS, Bill. If we lose the magnetic field, we'll lose our entire "shielding" and we'll be so badly zapped by all kinds of energy that the GPS will be the least of anyone's concerns. With all the money you save not buying sextant stock, you can buy deep mine shafts. No magnetic field for any length of time would mean some serious problems for life as we know it. Unless it flips real fast...not good at all. No one really wants to spend the money on the basic science needed to look into this in real detail, it just isn't sexy enough, or urgent-seeming enough.
