Yeah the civilian signal has no cipher / integrity-checking. The military signals do have those (and it chirps at 10x the rate of the civilian signal).

- amelius 7y agoMakes you wonder if nobody considered that an attack of civilian systems could be used strategically in warfare.

- GhettoMaestro 7y agoOh absolutely they do. That's why they reserve the right to turn off the civilian signals in an extreme time of war. In reality would that happen? Probably not. There are multiple GNSS constellations these days, so just denying GPS is probably not a safe bet (you can buy civilian uBlox chips for $<50 that are tri-band...) I love reading about the military aspect of GPS. It is really fascinating the use-cases they plan for. Hopefully they never actually are used in such an extreme scenario.
