 I agree that the way it is currently phrased is misleading (to the point of being wrong), but some "location systems" use multiple factors to increase their accuracy.  A good smartphone will use GPS together with signal strengths to wifi routers with known locations together with its compass to increase accuracy above that which it could obtain from GPS alone.  I've only taken little glimpses into the issue professionally but if I were making an algorithm for such a thing I'd also use input from the accelerometers.  In any event, I'd most certainly use the built-in compass.  Cheap estimation of direction of travel.  Of course I'm just being pedantic with all of that.  The difference in accuracy for such a scenario would most likely be minor to the point that nobody would notice.  I just kind of think the algorithms that try to combine all that sensor data are cool. --[[Special:Contributions/162.158.62.51|162.158.62.51]] 01:24, 15 January 2019 (UTC)
 Granted no one has ever experienced and documented a magnetic reversal event, however, would it be possible for the magnetic flux to cause errors on magnetic media? (eg HDD, credit cards, floppies, cassette, VHS, etc) If it were a cause for alarm, would a faraday cage be useful in protecting against the effects?
