Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

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.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

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.

Unprecedented GPS jamming attack affects 1600 aircraft over Europe (www.newscientist.com)

A 63-hour-long marathon of GPS jamming attacks disrupted global satellite navigation systems for hundreds of aircraft flying through the Baltic region – and Russia is thought to be responsible

Russia is suspected of launching a record-breaking 63-hour-long attack on GPS signals in the Baltic region. The incident, which affected hundreds of passenger jets earlier this month, occurred amid rising tensions between Russia and the NATO military alliance more than two years since the start of Russia’s full-scale invasion of Ukraine.

“We have seen an increase in GPS jamming since the start of Russia’s war against Ukraine, and allies have publicly warned that Russia has been behind GPS jamming affecting aviation and shipping,” a NATO official told New Scientist. “Russia has a track record of jamming GPS signals and has a range of capabilities for electronic warfare.”

I work developing the next generation GPS satellites, and half of my job is dealing with defeating jamming. Without giving specifics that can only be shared in a SCIF, jammers are for small regional use, not for large scale usage. RF power drops off at 1/r^2, so doubling the distance requires 4 times the power. A normal person can buy a jammer that handles a few hundred feet around their house or car. It is 100x harder to cover a city block of buildings and is mostly restricted to governments (my math could be off on that, since RF isn't my specialty). Going from jamming a city block of government buildings to jamming flight traffic in a small neighborhood is roughly 100 times as much as that power. Going from that small neighborhood to blocking a very small country is 100 times as much as that power (or 10,000 as much as the power of a big jammer). Doing the same thing but with multiple RF signals is even harder.

I can't talk about Russia's specific capabilities, but even for Russia it wouldn't be easy outside a small region.
