That jamming near Kaliningrad must surely be impacting the Russian residents as well, right? Unless it is very carefully aimed which seems unlikely since it is also trying to cover a very large volume.

>must surely be impacting the Russian residents as well, right? They don't give a fuck. Was watching a youtube video by a russian the other day talking about war & sanction impact and things like ride sharing apps literally say on screen the location is going to be wrong and to select pickup spot manually. It's just assumed to be fucked as a given even at an app development level

They don't even have internet anymore...

Why lie? It _is_ a tourist location, with > 2mln tourists annually (for their 1 mln permanent population). It also has quite a diverse economy, with Avtotor being a major car assembler (though not quite what it was pre-war), a fishing industry, amber mining, a TV manufacturer, &c. With a significant military presence, of course, but "giant military base in the middle of nowhere" is just ridiculous.

Crazy what the Russians destroyed... (you?) https://en.wikipedia.org/wiki/K%C3%B6nigsberg_Castle

Yes, we Russians are entirely responsible for British carpet bombing.

(I, of course, do not agree with the decision to demolish the remaining ruins in 1968; it could have been handled better.)

Yes, it's very wide spread and not carefully aimed at all. It's also not done by satellite but a ground based station. https://gpsjam.org/

That covers most of Poland, wtf

>I wonder if we can do something now that we know the source. Russia signed the 1967 Outer Space Treaty (OST) in 1967, this may be a treaty violation of this or other treaties, something like that or retaliation regarding it may be possible. You can hack the satellite, or use other electronic warfare options to jam or interfere with it's operations. You can shoot it down with a missile. The X-37B is in space right no…

> You can shoot it down with a missile. Obviously a bad idea, but frying it with some sort of high powered electromagnetic pulse would seem the smartest option with plausible deniability. I wonder if the US already has such weapons in orbit.

Realistically, how many people could do this ?

No one gives a fuck what russian residents are thinking about it. And if they start to talk about issues - police will quickly force everyone to shut up.

Thats true, but its also true that most russians support this war. Maybe they dont say it, but they are the soldiers in the trenches, mechanical engineers building missiles, software developers building their military software, Oil/NG workers that fund the war and so on

I'm sure that if you ask any of them, they would say that they don't have a choice. Same as western IT developers that continue to support the enshittification of the internet. They don't have a choice. /s

If you gave me a million dollars, I could do it. Someone else would have to aim it, but it shouldn't be that hard to do.

Your local cellphone towers already provide a more accurate position beacon signal for GPS modules in most parts of the world. Additional RF beam-forming in G5+ systems also make it impractical for lamers to jam long-distances due to limited coherent signal propagation. Indeed, amateur Hams have caught Russian ships jamming/spoofing local port traffic several years before the various official overseas conflicts start…

Agreed about cellphone towers providing accurate position, but not with enough precision and highly dependent on the number of towers in the vicinity. What i started building is for a highly unlikely scenario which is ; no internet + no GPS + no cell tower.

I have this idea that I'll get Bosch 9-DoF sensors onto every lane of every road, at least twice a month, then any other thing on a road can use a Shazam - like waveform lookup to determine where they are.

I didn't come up with this for dead reckoning, it's more for, um, autonomous cars to be able to avoid potholes and stuff.
