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.

It wouldn’t matter against jamming though. You just need a jammer that screams louder
Yup. As long as you’re transmitting via radio waves, if something on that frequency “screams” louder, you won’t get the original signal. That’s why the FCC has strict rules against radio interference. About the only way you could get past that would be some sort of laser guided/optical communications, but would be damn near impossible given the number of planes and weather conditions.
Luckily the louder something screams the more easy it is to pinpoint.
I mean, doesn’t matter. We pinpoint russia and then what. Sure, we can retaliate and block their comma, and radio communication doesn’t work for both of us. We can always invade, but a load of political capital is needed, and the west doesn’t exactly have the most ammo ever right now.
Finally, I think the true source is this
It's nice that they "scream" there. It's the way you know that they are hiding their ammo and weapons routes there. Instead of complaining, we should target these routes. Hey... they are outside russian borders... so....
"Our system is unjammable! Just make sure this laser receiver has clear line of sight with three satellites way up in geosynchronous orbit at all times."
"You're fucking with me, right?"
No . That's how it would work. That's why we don't use it, because of things like weather, birds, space debris, and other planes. its more secure but technically very difficult.

It would matter if they chose not to jam certain frequencies due to some agreement.
Thinking only of GPS-like services, there are multiple suppliers who could take advantage of Russia jamming other services. GPS is only one, owned by the American air force. Other suppliers might be more open to making agreements with Russia. Money can make things happen.
I'm not saying it's like that, only that it is possible for bad actors to benefit from playing on both sides in a jamming war, just like any other kind of war.
In a war like this they jam everything and anything they can. No commercial solutions would be loopholed out of it.
... unless money.
Unless they are on a different wavelength from GPS, which is what Xona is doing.
Ok, then they just block that one
Do you think country-wide jamming of a high-power radio signal is easy? The magnitude of difference between jamming a building and jamming at airline altitudes or at long distances is massive. You don't just go out and buy a jammer that blocks GPS for a country.
I don’t think that for an individual it is easy. But for a country as large as Russia (even with a somewhat pathetic economy)
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.
