World News
A community for discussing events around the World
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.
-
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 OCTOBER 19 2025
-
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.

I watched a video on this recently. Really interesting, especially how the researchers figured out it was a Russian satellite in a really high orbit. All it takes is a low-power burst to overwhelm the GPS network because it runs on such low powered, sensitive signals. They theorize the Russians were testing for very brief windows to see how well it world work. They could jam these signals anywhere over the Earth. Same for other nations too.
I watched the Veritasium episode on it just yesterday! The other theory is that it was actually being used for covert signals and the disruption was secondary.
Considering the impact of these tests, that doesn’t seem likely. You wouldn’t be sending covert messages in a way that would be so heavily scrutinized. I know it was a theory presented during the video, but that’s just journalistic integrity.
And ultimately, even if they were covert messages, now they also know they can disrupt gps
I think the point was less about making the messages undetectable as it was about making them unjammable. In order to stop their transmission, we would have to essentially shut down GPS for the entire EU. So you might use that frequency to send critical, must-have messages.
Especially once a second signal was noticed that was almost exactly the frequency used by the Chinese GPS system, as mentioned in the Veritasium video.
I thought that was the cover story. They deliberately used a channel partially in the bandwidth for some deniability. It isn't like they didn't know what bandwidth GPS used when they designed the satellite.
If I recall correctly, the idea was that they might have used that part of the band deliberately so that it couldn't be jammed without also jamming GPS. Either way, we're just guessing.
Yes, that's the video I watched. Good stuff.
last I checked that channel was owned by private equity so take it with a grain of salt
The signals aren't very sensitive, quite the opposite, they're chosen because they can be very easily detected even at low powers. If you want to jam GNSS from the ground you don't need a lot of power because the satellites are so far away and their signal is so low. If you want to jam it from a satellite you need quite a lot of power, especially if you consider that the suspected satellite constellation has twice the apogee of the GPS constellation. Also you don't need a burst of power, you need sustained power to really jam GNSS, the suspected satellites only did bursts because they're suspected of just testing their system.
GPS satellites send at like 25W of power. Naively I would think you could make that 2.5kW on a satellite without issues, probably even more.
I deal with this every day with the dark fleet using four enterprise AIS tracking systems and can 100% confirm this is accurate about GNSS systems.
please by all means share this video
It was probably this one by Veritasium.
Yes, that was it. Thanks.
