The theory that they broadcast communication on a band near GPS in order to discourage jamming of their early warning system sounds likely. Flexing the ability to jam GPS is pointless, since it's obvious that any state actor who has military satellites in orbit has considered this option or have the capability already. Therefore, the disruptions must either be regular tests of the capability, or just actual communica…

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
Don't worry though, it's been condemned in a sternly worded letter: https://www.icao.int/news/icao-assembly-condemns-gnss-radio-...
tl;dr - it was Russian satellites
This tl;dr is actually in the tl;dr on the linked page. We're doing tl;drs for tl;drs now?

>This paper analyzes and identifies a space-based Global Navigation Satellite System (GNSS) interference source that has caused scores of powerful transient wide-area interference events over continental Europe, Greenland, and Canada since 2019. While terrestrial or near-terrestrial sources are primarily responsible for the recent uptick in GNSS interference worldwide, space-based interferers are of special concern given their potential for vast geographic reach and their portent of a qualitative escalation in GNSS interference. Based on data collected between 2019 and 2026 from a network of terrestrial GNSS reference stations, this paper (1) develops a received-power-based detection framework; (2) details the spatial, temporal, and spectral patterns of wide-area interference events caused by the source; (3) presents and analyzes identification techniques that blend received-power and time-difference-of-arrival measurements; and (4) applies these techniques to confidently identify the GNSS interference source as a constellation of Russian early warning satellites in Molniya ("lightning") orbits.

Why is Ukraine not jammed in this map? Shouldn’t that be Russia’s priority?
Just as Iran jams GNSS, and Venezuela jammed GNSS ahead of the attack. Didn't really help though.

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.
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.

Overall it seems to be an overfitting the observation to the wider intent of a malicious actor.

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)
Err what? No, conventional radio broadcasts can be received with a low noise amplifier and a tuned filter. The received GPS signal, at ground level, is lower than the thermal noise floor. And the 1.023MHz code is modulated on the RF carrier anyway.
So correlating it with a sine wavelet?
Interesting to see that they are able to identify the specific satellite. I wonder if we can do something now that we know the source. Working on construction projects on the Romanian coastline (just South of Ukraine) and on the Polish continental waters (just West of Kaliningrad) we experienced jamming on a daily basis.
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.

> They're still free to move about the continent, make investments, do whatever Except that's not true at all, is it? See: https://en.wikipedia.org/wiki/International_sanctions_during...
It's not completely true, but there are hundreds of thousands of visas given to Russian tourists each year by European countries, something that's hopefully will get corrected soon. > According to data cited in Wednesday's letter, which was seen by Reuters, 477,878 Schengen visas were issued to Russian citizens for tourism in 2025, up from 440,558 in 2024. https://www.reuters.com/world/sweden-urges-eu-tighten-rules-.…
