Rules (2024-08-30)
- 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.
- 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 When you post outdated/historic articles, add the year of publication to the post title.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.
- 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.
- No bigotry, sexism, racism, antisemitism, dehumanization of minorities, or glorification of National Socialism.
- 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).
- If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
- Light-hearted content, memes, and posts about your European everyday belong in !yurop@lemm.ee. (They're cool, you should subscribe there too!)
- 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.
- 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.)
(This list may get expanded when necessary.)
We will use some leeway to decide whether to remove a comment.
If need be, there are also bans: 3 days for lighter offenses, 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 mods: @federalreverse@feddit.org, @poVoq@slrpnk.net, or @anzo@programming.dev.

This is an absolute basic necessity for a European Starlink, isn't it?
Well, to be able to independently launch it: yes. But once the satellites are up, who cares about the car dealers-in-chief?
& There's already Eutelsat; their satellites already seem to be providing internet much like Starlink: https://www.eutelsat.com/de/satelliten-dienste/satelliten-internet-breitbanddienst.html
Eutelsat has geosynchronous orbits, which allows them to provide service over a much larger area per satellite and doesn't require very many satellites to serve a consistent geographical area as the earth rotates and the satellites orbit the earth.
Problem is, though, geosynchronous orbit is 35,786 km altitude. Light travels at 3.0 x 10^8 m/s. So any signal takes 120ms to get to the satellite, and 120 ms to return. Any signal is going to have a 240ms latency at a minimum, and that's just physics.
Starlink satellites have an altitude closer to 600 km. Light only takes about 2ms to get to that altitude, and 2ms to return. So the satellites add only about 4ms, which makes for easier and more seamless communication.
In order to compete with starlink for most typical Internet applications, it'll require a bunch more satellites orbiting at much lower altitudes.
Eutelsat merged with OneWeb in 2022, which has satellites orbiting in LEO at 1,200 km.
So I suppose they also have access to that.
