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.
>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
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.
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
Jamming in general will affect everything using those frequencies (and potentially more besides) in a given area, so if you're using it you're weighing up the effects it'll have on your stuff as well. (early in the current Ukrainian invasion, reportedly Russian electronic warfare units were screwing up their own side more than the Ukrainians)
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.
1) with the exception of probably a few pensioners (who also depend on gov’t funding), everyone in the area is dependent on the military. It’s a giant military base in the middle of nowhere.
2) anyone not military (and hence in on it), is a pensioner or the like and won’t give a shit about GPS.
This is not a thriving urban metropolis or tourist location.
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.
The city has half a million residents and the oblast has a million residents. There's restaurants, museums, grocery stores, car dealerships, parks, zoo's, malls, stadiums, factories, train stations, an airport, ports etc etc. It's a real place.
>That jamming near Kaliningrad must surely be impacting the Russian residents as well, right?
Russia does not care, nor does it care about its population.
Where are you from?
I ask because you have western privilege, like me, and assume our governments care about its people. Why I lucked out being born in Sweden, the more I learn about the world, the more I am convinced I lucked out ahahaha.
Yeah, same with traveling by boat in the Baltic Sea, been continuously GPS-jammed since 2022 or something annoying like that, basically the entire South East-coast of Sweden been unnavigatable with GPS since then.
>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 now and interfering with space assets is a pretty obvious possibility for why it exists at all, but it's secret so nobody says these things.
If you start shooting down stuff in orbit, it'll invite retaliation, but even without retaliation there's a huge risk of a Kessler syndrome (especially with all the stuff that SpaceX has put into orbit in recent years).
No, Kessler syndrome is pretty unlikely in this case. All of the guilty satellites are in Molniya orbits. Debris from destroying them would not greatly effect geosynchronous orbit or the low earth orbits used by Starlink.
> especially with all the stuff that SpaceX has put into orbit in recent years
I've heard this repeated a lot but I've never seen anyone do the maths. StarLink satellites are all in very low orbits, so intuitively it seems like most debris from a collision would just end up deorbiting.
90% of starlink satellites are >400km in altitude. They aren't in very low earth orbits where that intuition even might be correct. They're above the space station.
I've definitely seen math done - though I'd have to dig it up again. I think in FAA filings.
I've thought about this before - do you actually need to "shoot it down" (make it explode)? What if you just nudge it a little and either make it spin or change its orbit? If your missile can reach the satellite then these seem like things that should be possible, no?
Depends, if you nudge it only a little, its own onboard stabilizers / thrusters should be able to correct it. It'd have to be more than its own systems can correct for.
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.
I doubt it based solely on that there are multiple interviews including from one of the paper’s authors. Given that Veritasium is a very well known channel at this point I wouldn’t be surprised if they were contacted instead and then roughly coordinated the timing of the paper and video release together.
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 communication. Right?
> The theory that they broadcast communication on a band near GPS in order to discourage jamming of their early warning system sounds likely.
Is it? If it is an early warning system, could it be jammed briefly so it would fail to warn, couldn't it? It will be a global disruption of GPS, but a brief one and I'm sure people wouldn't be concerned of it due to other news.
> Flexing the ability to jam GPS is pointless
Do you believe that cutting sea cables is a sensible action? Or sending drones to neighbors? It is what they call "hybrid asymmetric warfare", I'm not sure how it is supposed to work, but presumably it may let them take over the world or something.
Probably they just strive to normalize deviations, to boil frog slowly. When people become used to some stupid actions they widen their repertoire, until everything short of tanks crossing the borders became just normal news noise nobody reads twice.
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 GNSS signals are very low bandwidth as comms channels go)
> 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 threshold. It's only by correlating with the PRNG stream [1] that the data signal can be detected at all [2].
[1] The PRNG stream is 1023 bits at 1.023Mbps, so repeats every 1ms, and only autocorrelates with the correct stream when they are aligned. When the streams are not aligned, the data looks like random noise, and each transmitter has a different LFSR configuration to provide a different sequence such that each stream has a low level of correlation with another.
[2] The PRNG stream bits at 1.023Mbps are exclusive-or'd with the data stream at 50bps, so when the decoder is using the correct PRNG and sequence offset, exclusive-or'ing with that produces detectable long pulses at the expected 50bps.
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)
> 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.
Forget "state actors", truck drivers have taken out entire airports with GPS jammers:
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.
> 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 […]
I'm aware of the FAA's MON, Minimum Operating Network.
Exactly: that doesn't help boats. Or people in cars. Or farmers:
yeah, I have to admit I was commenting on possibilities here without having gone into the article yet -- having now looked for real, I agree that the disruptions don't seem very useful for actual jamming and repeatedly like this for years across satellites and bands in this specific way doesn't make sense for some mistaken targeting either.
There is a very good reason to do this. Suppose you had a device that would make the shoplifting detectors at stores go off. The first time you did it everyone would get hassled. And the second time and so forth. But if you kept doing it eventually the employees would stop caring. Then you just walk out the door with your stuff.
The video did not settle on the jamming of von der Leyen plane on approach to Plovdiv, but AFAIR it was a (likely unintentional) lie.
Never acknowledged by von der Leyen nor by her press secretary because it exposed the lack of basic world knowledge around von der Leyen and her office.
TLDR: Neither von den Leyen nor her office knew about ADB-S nor about the multiple services that collect ADB-S broadcasts and republish, and there was none around who could stop them from announcing an embarrassing lie.
Probably because some missing mention of some specific thing you care deeply about doesn't imply "lack of basic world knowledge" for an entire political office, really strange thing to say and most likely why people are downvoting. It's neither kind, curious and definitively a snark/swipe that doesn't really add anything to the point you were trying to make.
If you listen to the press conference, Podesta (the press secretary) spoke about the plane circling and not being able to land. When preparing the press conference, she should have checked if this obvious lie can be obviously disproved, but she did not. This probably means that she did not know this was a lie, but then someone who ordered this to be announced knew.
My bet is that von der Leyen or her close aide told Podesta to announce the lie in these terms, and the thing that worries me as a European is that there was none to warn these war-mongering ladies that they are making a mistake. This whole situation screams for an intern that sets up the mics and has a callsign and who can stop Podesta as she walks to the pied de stal of shame and explain that the position of planes is monitored all the time and is public information.
But I bet that all their interns are servile 3rd generation eurocrats.
P.S. The whole press conference (and many others) are fascinating to listen to. The language these people use is softened by the media. What do you think von der Leyen was doing on that plane? She was going "along the frontline" to inspect our preparedness for war where "the frontline" is the Eastern EU border.
P.P.S The story made rounds in EU circles, and there was a parliamentary question offering a chance to apologize, but von der Leyen chose to ignore it.
I don't care about Ursula von der Leyen nor her plane, merely explaining that if you try to extrapolate that a group of people don't have "basic world knowledge" based on not knowing a specific technology nor how/why it's used, the community is actually doing the rest of us a favor by downvoting it.
Want to discuss her office's use of a plane and how it's related to inspecting ammunition factories or whatever tirade you're going on about? Do create a new submission where that can be discussed, hardly related to the interesting story and methods of trying to track down GNSS interference.
It's a 9 months old story, even the MEP who wrote the question got over it.
I raised it because it was mentioned in the Veritassium video, but they stopped short of calling it a lie. They wanted to stay on topic, but the beauty of HN is that we can wander slightly off-topic and discover curious facts without being punished.
Yeah, curious facts like "it exposed the lack of basic world knowledge around von der Leyen and her office". Go outside brother, and get some fresh air before that too disappears :)
This thread seems an intended call for all NAFO warriors to quickly gather with anti Russian speech. Fair enough, there's a war, GPS jamming is to be expected. Maybe annoying for some, but a need for others. Hope the war to not escalate further, it will be more than GPS inconvenience.
I do not see any discussion of the power required for such wide-area jamming. Even as the useful GPS signal is quite weak at the ground level, this satellite would require power in kW range, right?
TLDR (conclusion from the paper):
"By a combination of these techniques the satellite Cosmos 2546 (NORAD ID 45608) was identified with high confidence as
one source of the interference. Further analysis pointed to the Russian Edinaya Kosmicheskaya Sistema, an early warning
constellation to which Cosmos 2546 belongs, as collectively responsible for the wide-area transient interference causing GNSS
degradation across Europe since 2019."
> Note that Cosmos 2546 was launched in May 2020 and so cannot be responsible for the interference events that occurred in 2019. Moreover, Cosmos 2546 was not over Europe during some interference events after May 2020. But during all events on the 75 days shown in Table 1 there was at least one EKS satellite above a 35∘ elevation angle with respect to every reference station that observed the interference. Thus, it is highly probable that the EKS constellation is collectively responsible for the wide-area transient GNSS interference events noted since 2019.
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 started. Not sure if it is government sponsored, or just various smuggling schemes like some ships spamming China harbors. =3
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.
You can likely bet that Space X with their thousands of sats deployed in space already has among them a few hundred stealth US military sats strategically placed and ready for the command to deal with the few Russky sats causing these problems ... think our Space Force.
It may not have attacked intentionally the EU yet, but a week ago there was an incident when a Russian drone apparently strayed away from whatever Ukrainian target it may have had, and it hit an apartment building in the city of Galati, in Romania, in the EU, injuring two people.
In the past there have been other incidents with Russian weapons reaching the neighboring countries from the EU, like Poland and Romania, but this was the first time when they hit a populated area, causing human injuries.
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.

Does ukrainians and romanians give a fuck, 'cause not many russians live in the north-west part of Black Sea? And the jamming there's from who?
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/
How far is the horizon from the tallest antenna mast in Kaliningrad?
Why is Ukraine not jammed in this map? Shouldn’t that be Russia’s priority?
That covers most of Poland, wtf
Why wouldn't it?

Crazy what the Russians destroyed... (you?)

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.)
Hey, old military installations (albeit ancient) are still a type of tourist attraction lol.
Most places in Russia are hunting and fishing locations too, hah.
The city has half a million residents and the oblast has a million residents. There's restaurants, museums, grocery stores, car dealerships, parks, zoo's, malls, stadiums, factories, train stations, an airport, ports etc etc. It's a real place.
I never said it wasn’t.
Killeen, Texas is also a real place.
How many people do you think don’t have at least a 2 degree connection to the US military?
Do you think anyone there is going to think twice about going along with what the military is doing? Or could if they wanted too?
And Killeen is far, far less isolated geographically.
It is like saying Detroit is military base because there are some military related buildings.
Uh huh
It is not. I.e. there is one of the largest passenger vehicle assembly line Autotor.

Nudge it long enough to deplete it's fuel reserves? Or just wrap the emitting antenna in tin foil...
> 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 ?
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.
I assume that satellites have protection against that - because of solar flares.
Kessler event oops, you know. I guess I know someone with several disposable satellites, I wonder if they could be bothered (but I guess not)

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.

I'm aware of the FAA's MON, Minimum Operating Network.
Exactly: that doesn't help boats. Or people in cars. Or farmers:

It doesn't help those that use GNSS for precise timing (TCXOes can only 'free run' for a finite amount of time before drift compounds 'too much').
Unless the actor happens to be a state that puts a great deal of emphasis on flexing & appearances regardless of how pointless it is
Or actual jamming mistargeted for some reason, or used because it was deemed necessary.
Repeatedly, over years, only for 2 to 5 seconds at a time? Seems unlikely
yeah, I have to admit I was commenting on possibilities here without having gone into the article yet -- having now looked for real, I agree that the disruptions don't seem very useful for actual jamming and repeatedly like this for years across satellites and bands in this specific way doesn't make sense for some mistaken targeting either.
There is a very good reason to do this. Suppose you had a device that would make the shoplifting detectors at stores go off. The first time you did it everyone would get hassled. And the second time and so forth. But if you kept doing it eventually the employees would stop caring. Then you just walk out the door with your stuff.
>Flexing the ability to jam GPS is pointless
No, Russia does these "tests" all the time to see and gauge the reactions. Ex flying just a bit into EU airspace.

The video did not settle on the jamming of von der Leyen plane on approach to Plovdiv, but AFAIR it was a (likely unintentional) lie.
Never acknowledged by von der Leyen nor by her press secretary because it exposed the lack of basic world knowledge around von der Leyen and her office.
Why downvotes?
Here's the press conference where it was announced: https://audiovisual.ec.europa.eu/en/media/video/I-276341
FlightRadar24 disproved the story shortly after: https://twitter.com/flightradar24/status/1962565122326700178
TLDR: Neither von den Leyen nor her office knew about ADB-S nor about the multiple services that collect ADB-S broadcasts and republish, and there was none around who could stop them from announcing an embarrassing lie.
> Why downvotes?
Probably because some missing mention of some specific thing you care deeply about doesn't imply "lack of basic world knowledge" for an entire political office, really strange thing to say and most likely why people are downvoting. It's neither kind, curious and definitively a snark/swipe that doesn't really add anything to the point you were trying to make.
I think you normalize the deviation, here.
If you listen to the press conference, Podesta (the press secretary) spoke about the plane circling and not being able to land. When preparing the press conference, she should have checked if this obvious lie can be obviously disproved, but she did not. This probably means that she did not know this was a lie, but then someone who ordered this to be announced knew.
My bet is that von der Leyen or her close aide told Podesta to announce the lie in these terms, and the thing that worries me as a European is that there was none to warn these war-mongering ladies that they are making a mistake. This whole situation screams for an intern that sets up the mics and has a callsign and who can stop Podesta as she walks to the pied de stal of shame and explain that the position of planes is monitored all the time and is public information.
But I bet that all their interns are servile 3rd generation eurocrats.
P.S. The whole press conference (and many others) are fascinating to listen to. The language these people use is softened by the media. What do you think von der Leyen was doing on that plane? She was going "along the frontline" to inspect our preparedness for war where "the frontline" is the Eastern EU border.
P.P.S The story made rounds in EU circles, and there was a parliamentary question offering a chance to apologize, but von der Leyen chose to ignore it.
> I think you normalize the deviation, here.
I don't care about Ursula von der Leyen nor her plane, merely explaining that if you try to extrapolate that a group of people don't have "basic world knowledge" based on not knowing a specific technology nor how/why it's used, the community is actually doing the rest of us a favor by downvoting it.
Want to discuss her office's use of a plane and how it's related to inspecting ammunition factories or whatever tirade you're going on about? Do create a new submission where that can be discussed, hardly related to the interesting story and methods of trying to track down GNSS interference.
It's a 9 months old story, even the MEP who wrote the question got over it.
I raised it because it was mentioned in the Veritassium video, but they stopped short of calling it a lie. They wanted to stay on topic, but the beauty of HN is that we can wander slightly off-topic and discover curious facts without being punished.
Yeah, curious facts like "it exposed the lack of basic world knowledge around von der Leyen and her office". Go outside brother, and get some fresh air before that too disappears :)
This thread seems an intended call for all NAFO warriors to quickly gather with anti Russian speech. Fair enough, there's a war, GPS jamming is to be expected. Maybe annoying for some, but a need for others. Hope the war to not escalate further, it will be more than GPS inconvenience.
"aybe annoying for some, but a need for others."
Who needs it? Russia? I guess Russia does not need war but it started it anyway.
I do not see any discussion of the power required for such wide-area jamming. Even as the useful GPS signal is quite weak at the ground level, this satellite would require power in kW range, right?
Satellites have multi kW solar panels
TLDR (conclusion from the paper): "By a combination of these techniques the satellite Cosmos 2546 (NORAD ID 45608) was identified with high confidence as one source of the interference. Further analysis pointed to the Russian Edinaya Kosmicheskaya Sistema, an early warning constellation to which Cosmos 2546 belongs, as collectively responsible for the wide-area transient interference causing GNSS degradation across Europe since 2019."
Additionally:
> Note that Cosmos 2546 was launched in May 2020 and so cannot be responsible for the interference events that occurred in 2019. Moreover, Cosmos 2546 was not over Europe during some interference events after May 2020. But during all events on the 75 days shown in Table 1 there was at least one EKS satellite above a 35∘ elevation angle with respect to every reference station that observed the interference. Thus, it is highly probable that the EKS constellation is collectively responsible for the wide-area transient GNSS interference events noted since 2019.
Hmm - the timing is uncanny that only 2 days ago I started building a dead reckoning system.
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 started. Not sure if it is government sponsored, or just various smuggling schemes like some ships spamming China harbors. =3
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.
There's a live map too: https://gpsjam.org
You can likely bet that Space X with their thousands of sats deployed in space already has among them a few hundred stealth US military sats strategically placed and ready for the command to deal with the few Russky sats causing these problems ... think our Space Force.
Completely different orbits to make this possible
Being engaged to warfare with Russia and being jammed in response. So weird.
Russia is the aggressor. What do you propose?
Eat more propaganda.
Russia attacked Europe, this is just another reminder that they are our enemies and we should be sabotaging their systems in turn.
Relax, Russia didn't attacked Europe yet (if you mean EU).
It may not have attacked intentionally the EU yet, but a week ago there was an incident when a Russian drone apparently strayed away from whatever Ukrainian target it may have had, and it hit an apartment building in the city of Galati, in Romania, in the EU, injuring two people.
In the past there have been other incidents with Russian weapons reaching the neighboring countries from the EU, like Poland and Romania, but this was the first time when they hit a populated area, causing human injuries.
The GPS jamming has been measured since 2019.
tl;dr - it was Russian satellites
How unsuprising.
This tl;dr is actually in the tl;dr on the linked page. We're doing tl;drs for tl;drs now?
In the future abstracts will be called Tilldars and no one will remember it came originally from trying to pronounce "tldr"
