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/ https://gpsjam.org/

  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.

    Maybe there are reasons Europe is pulling away from the US? The current US president has threatened to invade European territory, is attempting to impose Russia's preferred "peace" plan on Ukraine, and has recently relaxed sanctions on Russia. He also consistently denigrates the military support Europe's given to the US in the recent past. The US has basically cut aid to Ukraine to zero, while Europe continues to supply them, which is currently the best way of dealing with Russia, sucking their military power into a war their not going to win.

      And? When the Russians invaded Georgia in 2008, Europeans inked a deal for a second gas pipeline with them, Nordstream 2. When they annexed Crimea in 2014, Europeans went to the Sochi Olympics (which happened that same year) and went to the World Cup in 2018. And this is before you take into account the dozens of smaller incidents. Those aren't "threats to invade European territory", not even ones that were ignored by the military. Those were shooting wars that got people killed and redrew the map in Eurasia. Europeans continued to do business with Russia more-or-less unimpeded until 2022. Many Russians still live, work, and do business in the Schengen area. The US Congress passed a bill to fund Ukraine this week.

        Remind us, why US Congress funds a country on literally the other side of the planet?

        Because the world is actually very small and Ukraine winning helps the US

        It is in this position thanks to US in the first place.

    US has got itself compromised by Russia. US president is a Russian asset. Breaking away from unreliable former ally is the logical thing to do for Europe's security. Funny how Ukraine situation started improving once they have severly limited sharing information with the US.

  Not only Poland, they have jammers around St Petersburg as well which affects Finland, there have been reports about boats losing GNSS reception in Swedish waters, etc. This has been going on for years. Don't worry though, it's been condemned in a sternly worded letter: https://www.icao.int/news/icao-assembly-condemns-gnss-radio-frequency-interference-originating-dprk-and-russian https://www.icao.int/news/icao-assembly-condemns-gnss-radio-...

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

  GPS interference is estimated from ADS-B data which is broadcast by airplanes so that they can be tracked. The lack of data over Ukraine is because their airspace is closed to civilian flights.
- sorenjan 4mo ago
  The GNSS jamming in Ukraine is mostly from Ukraine themselves, to defend against Russian drones and guided bombs. Just as Iran jams GNSS, and Venezuela jammed GNSS ahead of the attack. Didn't really help though. https://arstechnica.com/gadgets/2026/05/nasa-satellites-can-spot-gps-jammers-on-earth/ https://arstechnica.com/gadgets/2026/05/nasa-satellites-can-...
  - codedokode 4mo ago
    Probably because Wester jammers are used from ground and drones have antennas on the top side. For comparison, Russian satellite can jam the signal from above and on a large area. Russian technology is superior.
    - sorenjan 4mo ago
      If Russian GNSS receivers wasn't affected they wouldn't need fiber optic drones, Ukraine is jamming both the small and large drones. Russia have both their own Kometa system to try to filter out the jamming signals, and plenty of Chinese tech as well. Russian technology is very dependent on both western and Chinese tech, yet they couldn't even defend their own oil refineries in St Petersburg or make any relevant progress along the front in years.
      - codedokode 4mo ago
        To be fair, USA also could not defend their allies and their bases, and didn't move the frontline in Iran as well. And if Iran buys a submarine capable to launch missiles from a friendly country the situation might get worse.
