Wait, did that article fail to mention cruise missiles? ’Cause, today I learned that some buildings have cruise missile shields around them (implemented as anti-GPS emanations).
I know nothing about this topic, I’m just curious. I would think that would be fairly easy to counter because I would think that the last, say, 1/2 mile of a cruise missile’s flight would be more or less ballistic, or could be. Do cruise missiles actually require guidance right up to the moment of impact?
Many of them use active guidance in the final stages, but that guidance is often informed by computer vision and 3D map fitting; I agree that is seems unlikely that jamming GPS would interfere with the terrifying accuracy of modern missiles.
But perhaps its good enough for north korean ones.
Ah, yet another arms race. They could be using a targeted anti-UAV system instead of such heavy-handed blanket interference. Meanwhile, vision-based UAV guidance is a hot research topic.
