That covers most of Poland, wtf

Why wouldn't it? The behavior will continue until a consequence is imposed. Not on regular Russians, mind. Their ruling class. They're still free to move about the continent, make investments, do whatever. Currently Europe seems to be more interested in breaking away from the US than dealing with the power that has killed hundreds of thousands on their own continent.

Europe seems to be interested in neither. As a rule, elites in any country are not concerned about hundreds of thousands of their citizens being killed. I have yet to be proven wrong.

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.

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/

Why is Ukraine not jammed in this map? Shouldn’t that be Russia’s priority?

Because the video is based on the research done in this article, it even specifically calls out the article's authors in the description

Is that normal? To promote a research paper in ArXiv so heavily? I think the parent comment’s concerns still apply, saying a large, well-funded YouTube channel is specifically releasing coordinated content to promote this prompts more questions than it answers, in my mind.

Yes it is common, just not always to the scale of a Veritasium video. Usually it’s just the press office for a university putting out a press release or a summary article in Scientific American.

But in the case where the story is interesting to a larger audience, having a push behind a story across non-academic media is not unheard of. If you can get some media coverage of an academic topic, it can be very beneficial to the researchers’ careers. One goal for a researcher is to bring notoriety to their research, to their institution, and to the field in general. This is the main motivation I see.

The authors may have pushed the arxiv paper out earlier due to the timing of the release of the video.

There is definitely value in having a demonstrated as opposed a simply supposed capability, though. And actions that are 'almost-certainly-but-not-completely-provably-us' is very much something Russia likes to do. (One question I would have about the comms theory is whether the amount of power being used would be reasonable for that use-case. Jamming tends to be much higher power than just communicating, but also GNS…

> One question I would have about the comms theory is whether the amount of power being used would be reasonable for that use-case. Jamming tends to be much higher power than just communicating, but also GNSS signals are very low bandwidth as comms channels go GPS is suprisingly low power. I believe the satellites themselves transmit between 20W and 50W, and in general the signal is quieter than the background noise…

FWIW this is how almost every communication system works. They're all weaker than background noise (e.g. sunlight) but you extract them by correlating with some kind of carrier signal (often but not always a sine wave)

>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... https://www.bbc.com/news/articles/cr510de17jlo

Bit of a reach, their internet may be restricted to a degree, but they sure do have internet... my partner calls and video calls their family back in Russia daily from half way around the world.

Kaliningrad is one big military base.

Doesn't sound like you have actually been there. Military is a major employer, but in a territory inhabited since 1944 there are generations of people born there who didn't see a reason to live, the same foreign gastarbeiter as in any Russian city, etc. I.e plenty of ordinary people who could be inconvenienced.

reason to leave, sorry.

I don't think you meant it like that, but Kaliningrad, or Königsberg is inhabited since a bit longer. For example Immanuel Kant lived and taught there.

Obviously. But since the Russian occupation infamously expelled the natives completely, when I talk about “inhabited since 1945” in the context of people living there now, I’m obviously referring to the Russian population.
