GPS and other Global Navigation Satellite Systems (GNSS) are used in everything from cellular communication networks, to basic consumer goods, high-end military systems, and stock trading inputs. But these systems are vulnerable: by attacking positioning, navigational, and timing (PNT) data through electronic warfare (EW) capabilities, state and non-state actors can cause significant damage to modern militaries, first-world economies, and everyday consumers alike.

I was just thinking the other day that we are getting close to the time when a small state or a big non-state actor could take out the GPS system with cheap rockets.
However, with cheap, low-earth satellites coming on board, we may also be close to the point where a large military power could launch their own network quickly and in a way that could not quickly be taken out short of massive EMP.
This is a new wrinkle
