    What happens to GPS if:

    1) Signals are jammed or hacked

    2) Your electronics die

    3) Terrorists or rogue states use the system for targeting and the Government must degrade the signals or shut it down

    4) Killer satellites knock out ours or broadcast false signals

    5) Due to EMP from solar storms or nuclear detonation, the signals die
