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…

Why these capabilities, if they exist, were not used to send Iranian drones to a wrong target? Maybe because they do not exist. Israel definitely would be happy if thousands of drones were rerouted to a neighbour country or into the sea.

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-...

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.

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.

>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

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.

I’ve briefly been somewhere for a few days with significant GPS interference, and yes, basically phone navigation doesn’t work reliably.

For me it was a minor annoyance while driving but presumably any apps that rely heavily on GPS (Uber, food delivery) just wouldn’t work very well or at all

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.

It doesn't sound that conspiratory: someone of the millions of subscribers of Veritasium watches the video and thinks that is good content suited for HN, but instead of linking the video itself (rarely video links raise upvotes here) it links the primary source.

But even if the paper was "promoted" (i.e. a link submitted), what is bad about it? People seem to find it interesting, and unless there are upvoting bots involved, posting links is the raison d'être of this site.

Forget "state actors", truck drivers have taken out entire airports with GPS jammers: * https://www.cnet.com/culture/truck-driver-has-gps-jammer-acc... People like the Resilient Navigation and Timing Foundation have been trying for years…

The US still has a fairly robust network of VOR's / VOR with DME / VORTAC stations. Good for navigation, but there's no timing component, beyond what's inherent in how they operate. Admittedly, that'll never be of use outside aviation as its line-of-sight only. But if the sun threw a Carrington event (or worse) at us, I think a lot of western aviation could carry on.

A lot of these were getting dismantled until quite recently, but given recent developments they should obviously be kept

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.

> 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.

> frying it with some sort of high powered electromagnetic pulse would seem the smartest option with plausible deniability Realistically, how many people could do this ?

This is not something individuals should be doing.
