The World Economy Runs on GPS. It Needs a Backup Plan

The most insidious tactic on the ground is GPS spoofing, using malicious software to broadcast phony signals and fool the receiver on, say, an aircraft into thinking it’s somewhere, or somewhen, that it isn’t. Such methods “would certainly work against Ubers, Waymo’s self-driving cars, delivery drones from Amazon,” and more, says Todd Humphreys, an aerospace engineering professor at the University of Texas at Austin.

Happy to see the article discuss the problem of GPS jamming and spoofing. That could become an increasing threat, especially against self-driving cars.

I thought aviation didn’t rely on GPS for navigation?

They still need GPS for periodic correction.
