  1. well wat if a nuclear bomb is air bursted and the EM burst breaks your gps? or your gps battery dies? I still use a compass and a map when back packing and it hasnt failed me in about 10 years (thats how long ive backpacked)

  2. Why use a sextant when GPS is available?

    In practical terms, you wouldnt. But, then again, being lost in the arctic, or lost on the ocean after a storm killed your electronics… times like that when “practical” is lost in the “unlikely event” splatter. Its nice to know how celestial navigation works – GPS is really not much different conceptually. Its also nice to be able to independently verify the accuracy of your GPS.
