When GPS fails


Recommended Posts

"Use your eyes" and orienteering are indeed good things for hikers and goecachers - but not always adequate for some scenarios. Particularly not those the original article mentioned, such as guiding a ship like this one:




There's more to GPS than finding caches.


... "Most people think of GPS as the system that runs their car sat-nav and tells their smartphone where it is ... but there is probably no area of industry, of commerce, or telecoms, that isn't now dependent on GPS. And if we lose GPS we lose them all."

Hmm, I didn't pick up that angle at all. The article did mentions several potentials some for outages - from solar storms to intentional jamming - that would affect GPS, GLONASS and other systems. I didn't see US system maintenance as an issue, at least not a key one.
