Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

As another commenter said, I don't think cryptography is the main problem.

You've got to be able to modulate some numbers out of the radio signal first before you need to be concerned if it's encrypted or not.

GPS signals from power conserving satellites are so weak that I'd imagine that overwhelming them with noise on all frequencies would be the easy answer. (Although there's a Big Brain hyper-cunning answer to that...).

Some GPS jammers are known to transmit, instead of noise, a bad signal which creates an offset in the timing to calculate a false position. But with encrypted military GPS, that's not as effective.

I don't think PGMs with M-Code GPS capabilities are being provided to Ukraine, but that is definitely something well outside of my casual knowledge base, so I'm open to being corrected.
