Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, islamophobia, dehumanization of minorities, or glorification of National Socialism. We follow German law; don't question the statehood of Israel.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in other communities.
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)
  10. Always provide context with posts: Don't post uncontextualized images or videos, and don't start discussions without giving some context first.

(This list may get expanded as necessary.)

Posts that link to the following sources will be removed

Unless they're the only sources, please also avoid The Sun, Daily Mail, any "thinktank" type organization, and non-Lemmy social media. Don't link to Twitter directly, instead use xcancel.com. For Reddit, use old:reddit:com

(Lists may get expanded as necessary.)

Ban lengths, etc.

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 7 or 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the primary mod account @EuroMod@feddit.org

Estonian officials said Russia has bolstered its electronic warfare systems near its border with the Baltic country.

The Russian army brought additional signals jamming equipment to the area around Kingisiepp, a town around 20 kilometers (12 miles) from the Estonian frontier, Interior Minister Igor Taro said at a press conference in Tallinn.

...

Such equipment has been used on the battlefield in Ukraine to disrupt drones’ navigational signals. However, electronic warfare also causes severe interference to the Global Positioning System, or GPS, used by commercial airplanes and ships.

Can't we counterjam them? They have more to lose in that area of the globe.

Being on the ground, they're a lot closer to the GPS receivers and basically overpower the real signal that has to come all the way from space. Satellites also have to very careful with their power use, so counter-jamming that method would be almost impossible.

You could install your own ground stations, but then it becomes a game of who has more electricity to burn.

Edit: Better antennas can help, but get very expensive very fast. Since they're really just adding more and more and more antennas.

The nice thing about jammers is that they're basically giant homing beacons though. Unfortunately, using them as such is pretty much an act of war.

Which is the whole point: provocation.

Oh no doubt. They're just baiting a response so they can play the victim again.
