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.

Russia leaves thousands of planes without GPS in northern Europe (english.elpais.com)

Several NATO members accuse Moscow of deliberately jamming positioning signals

GPS is no longer reliable around the Baltic Sea and northern Norway. Interference in the Global Positioning System (GPS), which has affected all NATO members bordering Russia for two years, has worsened in recent months. Alternative systems to GPS have had to be activated on tens of thousands of flights and the main Finnish airline has suspended one of its routes due to the problem, which is also disrupting maritime navigation. Several of the affected countries accuse Moscow of intentionally jamming signals with its electronic warfare systems.

Since the Russian invasion of Ukraine in February 2022, GPS interference has been recurring in Estonia, Latvia and Lithuania. These types of disruptions are common in and around conflict zones. Even so, in the last half year, the airspace of the three Baltic countries — in addition to that of Finland, Sweden and Poland — has been much more affected than at the beginning of the war. What’s more, thousands of ships have been navigating the Baltic without GPS since December, when the Russian army’s electronic warfare began in the Kaliningrad enclave. And in remote northeastern Norway, near Russia’s Northern Fleet base — which has eight of the 11 Russian submarines capable of launching long-range nuclear missiles — outages are almost daily.

They do, but compounding errors are always a problem with inertial navigation.

Instead of GPS, they can use fixed radio beacons like VOR and TACAN (which I think are both just US systems, but there are similar systems around the world and at major airports). This is basically the system that was in use before GPS.

EDIT: grammar

VOR is international, my local airport has one. TACAN is military only (though some can be used as a VOR by civilian aircraft), also international, and by the way originally British as per Wikipedia.

I understood everything in your comment! All those years playing FSX instead of going to school finally paid off!
