Iran is likely jamming Starlink
- ggm 9mo agoUnder packetloss my assumption is text is king, but I wonder if forward error correcting audio and video is actually better in some ways? Media is information rich. Maybe we're beyond a samzdat moment and the value in comms is contextual immediacy of live feeds, text can squeeze alongside. Long ago, broadcast quality TV was shipped as slow feed. Maybe a tiktok generation goes back there: use a phone on the street (probably surreptitiously) do post production and upload asynchronously on 30% packetloss or worse for redistribution.
- bawolff 9mo agoYou are acting like people dont upload videos anymore. The people filming protests in iran are probably not in range of their home starlink connected wifi. They are almost certainly filming stuff offline then uploading it later, not livestreaming.
- ggm 9mo agoYes. thats broadly what I think people will be doing. My concern was, under 30% to 80% packetloss, how well this works. I think the answer is, if you want to get media out, it works well enough, given enough time. I would be surprised if GPS blocking is enough to completely can starlink. It improves positioning but if you don't jog the antenna, given these things are in predictable orbit, you can probably get good-enough S/N without GPS info.
- tkel 9mo agoWhich governments are referred to as "regimes" is usually propaganda about how you should feel about them. Consider: all articles written about US using the words "The US regime".
- IlIlIlIIlIlIlI 9mo agoYes, a "regime" is basically a country where they wants to have control but can't for some reason
- epistasis 9mo agoI don't think I've ever read an article using the term "US regime," as that usually refers to an undemocratic or authoritarian government. You might want to clean up your information diet if you're reading lots of articles over the years with that term... Yes it is a value judgement, but Iran's government is nothing if not oppressive and authoritarian. Until recently the US had taken pride in being nothing like a regime, but that may change in the coming years.

- bulbar 9mo ago> Until recently the US had taken pride in being nothing like a regime, but that may change in the coming years. I tend to believe the US is already past that point. It's just people are not really realizing that yet. Might take the next election for them to realize. That will be to late however. I hope so much that this is wrong and the US turns out to be more resilient than it looks like from the outside though.
- codezero 9mo agoThis is my belief as well. My friend fled Syria after her mother was shot in the stomach by the police at the police station for asking to see her brother (I’m sure more was involved) and I have always kept in mind to look out for red lines being crossed at faster rates than before.
- ThePowerOfFuet 9mo ago>I don't think I've ever read an article using the term "US regime," as that usually refers to an undemocratic or authoritarian government. Pretty fuckin' big rock you've been living under for the last couple years.
- stein1946 9mo agoHow likely is it that those "protestors" are US and Israel propped and the plan is to do another regime change via this route? Isn't this "son of the late Shah" a guy from the US?
- Mikhail_Edoshin 9mo agoIt is 100% that.

- jeltz 9mo agoVery, but at the same time the Iranian leadership have been a really shitty government and ran the country into the gutter. People have genuine grievances.
- HauntingPin 9mo agoThe only way to believe this is if you're a Westerner being fed a purely US-centric media diet. Otherwise you'd know all the ways that the Iranian government has been failing their people recently and for a long time now, and how unhappy Iranians are with their government. You people act like people can't be upset at how they're being treated by their own government without being incited by an external actor. That's honestly quite the dehumanising and insulting way of looking at it. Also, if the US wanted to do a regime change, they'd just move in militarily a la Venezuela and Trump would be talking about it non-stop. He's not the subtle type, I promise. We'd already know if they were involved.
- Mikhail_Edoshin 9mo agoStarlink is primarily a military technology that is used both on a battlefield and to coordinate USA-backed "protests". Why, for instance, it just become free in Venezuela? Every country needs to be able to to defend itself from Starlink.
- CamperBob2 9mo agoEvery country needs to be able to defend itself from Russia, too, apparently.
- Mikhail_Edoshin 9mo agoNo, only US-backed puppets that US uses against Russia. For example, Russia has very good relations with Belorussia where the government wasn't lured into this role and did not let US to overthrow it.

- jonway 9mo agoWow this sucks! however if i were iranian brass i would do it too. IT/OT and IoT is not safe full stop. Pull the plug. It wouldnt be pretty over here either, also china already got us good (Volt Typhoon, OPM hack, why bother to list 30 or 40 more?)
- bawolff 9mo agoThe article seems quite speculative. I'm sure the Iranian regime would live to jam starlink, but i don't think we have any ability to know what is actually happening here. The article claims 80% packetloss. That's still 1 in 5 packets getting through. That is annoying but not going to stop information getting out. I also wonder, if all other coms are cut off, is it possible star link in the country is just overloaded?
- XorNot 9mo agoIn my experience 80% packet loss makes most common protocols basically unusable. Yes you can still get data out...but many apps will just fail due to timeouts and other things.
- bawolff 9mo agoI imagine the people with illegal starlink terminals are fairly tech savy and can use custom protocols. Living in Iran they probably already have a lot of experience with vpns and lower level protocols to evade censorship.
- aaomidi 9mo agoI wouldn’t imagine that no. It’s “illegal” but not hard to obtain
- onesociety2022 9mo agoIllegal just means there’s a black market. You pay some guy in cash and he gives you a smuggled Starlink terminal. Neither buyer or seller is likely to be anymore sophisticated here than someone trading in any other smuggled goods (cigarettes, alcohol, drugs, etc).
- queenkjuul 9mo agoI'm a programmer and even i wouldn't know where to start implementing a custom network wire protocol.

- deleted 9mo ago[deleted]
- dlenski 9mo agoHow do these tens of thousands of Starlink terminals get smuggled into Iran?
- aaomidi 9mo agoIran has a thriving black market through its borders
- HDThoreaun 9mo agoTrucks I assume
- Yaser_Amiri 9mo agoIran has a huge black market. Many things from refrigerator to small things are being smuggled to Iran, mostly from the mountains on Iraq border (also from Turkey border and from other Gulf countries. The government is not peaky about smuggling since Iran is under heavy sanctions and it's hard for the government to provide USD to legit traders on official channels.
- ACCount37 9mo agoNot too surprising, given that Starlink operates in Iran without a permit, "space pirate radio" style, and has something of a habit of making the access free when major protests happen and the government imposes a network blackout. Iranian government and Starlink have no love for each other, clearly. It's a pattern by now: whenever a government wants to do something awful, it shuts down internet access - so that no one can hear it, see it or coordinate a response. And Starlink becomes a lifeline that the regime would rather people didn't have. This is why all of those "national great firewalls" shouldn't exist in the first place. If you give a government a capability to restrict access to whatever it wants and enact a network blackout whenever it wants, it's a matter of time until it gets abused.
- ece 9mo agoIt's weird how Apple and Google don't get it, while SpaceX does.
- ACCount37 9mo agoStarlink isn't perfect, but at least it doesn't go for "it's so not our problem, we'll just make sure that every single VPN exit point Iranians use is GeoIP'd as Iran in our systems" like Google tends to, or "let's lick every authoritarian boot, we control the app distribution and our users will suck it up" like Apple does. Not even Starlink has the balls to oppose the likes of Russia and China directly - they aren't operating there without a permit, sadly. But at least they don't kneel before every two-bit dictatorship and cave to every single "we want you to do censorship on our behalf" demand. Way better than what most tech companies do now.
- ozlikethewizard 9mo agoI'm unfortunately inclined to not look at their actions so favourably. They operate solely in jurisdictions where the US state supports open destabilization, and dont where the political ramifications would be too high for the US. Makes them little more than an extension of the US imperialist structure. And this makes sense for an organization thats so highly reliant on federal support, vs Apple and Google who only have to just stay somewhat in the states good graces.
- hartator 9mo agoI candidly thought it wasn’t possible to block Starlink. I guess with motivated actors anything is possible.
- drivingmenuts 9mo ago[flagged]
- fridek 9mo agoWho is "we" and "them"? Don't you find it ironic, such a comment on a thread about protesting a regime which tries to control who does what?
- TMWNN 9mo agoStarlink has no ground stations on Iranian soil and is formally prohibited by its government, so there is nothing being "provided" to Iran, per se. Iranians smuggle Starlink dishes in, at great personal risk.
- jeroenhd 9mo agoIf it were impossible, China would've had reason to blow up their satellites in orbit. The US would do the same thing for Chinese satellite ISPs. Jamming on such a large scale is expensive, but it's hardly impossible.
- gordonhart 9mo agoThere’s no evidence that China (or anybody else) has the capacity to meaningfully harm the 9000+ satellite Starlink constellation.

- curiousObject 9mo agoIs this not only a side effect of Iran doing widespread GPS and GNSS jamming or spoofing?
- consumer451 9mo agoI am curious if there are any implications for the Russian invasion of Ukraine from this tactic working.
- GrowingSideways 9mo agoBoth sides are using starlink, yes? Also there's now guowang to contend with. I'm not sure how widely available access to it is. I would assume both sides are heavily jamming the frontlines. But presumably long range drone operations are more likely to use it.
- throwaway85825 9mo agoJamming is subject to the inverse square law.
- GrowingSideways 9mo agoYes, this is why it happens only on the front line
- Etheryte 9mo agoWhat do you mean, Russia has been doing the same thing for most of the war? The success relies on you controlling the territory, or at least territory close enough, so the results vary.
- krona 9mo agoIsn't Iran doing this from the air? That would be far more effective. In a contested space with AA everywhere that wouldn't be feasible (i.e. large parts of Ukraine)
- SXX 9mo agoIn a war zone any large high power jammer will be like supernova in the darkness visible for detectors from tens of kilometers away. So its gonna be immediately destroyed. Iran protesters cant find or destroy jammers though.
- perihelions 9mo agoSeems like a big flaw that low-orbit constellations have a dependency on GPS, which are high-altitude satellites. They're 40x further away and so have 1,600x greater path loss. Why can't they use their own satellites for this? > "But Starlink receivers use GPS to locate and connect to satellites. “Since its 12-day war with Israel last June," The Times says, “Iran has been disrupting GPS signals.”"
- archerx 9mo agoIf the GPS satellites are above the starlink ones how is Iran able to disrupt the GPS signals?
- BoardsOfCanada 9mo agoBy jamming the receivers on the ground
- archerx 9mo agoOk that makes a lot of sense, thank you.
- Neywiny 9mo agoFor legal reasons I base this off of nothing but just turn your jammer to the sky. Could get fancy and point out directly at the satellites since my understanding is it's pretty easy to know where they are. Edit to add: I do not mean the GPS satellites or the starlink ground terminals. That was not the question so that is not my answer. I mean the starlink satellites
- wizzwizz4 9mo agoThat doesn't work. GPS is broadcast, not bidirectional communication, so preventing the satellites from seeing the GPS receiver does nothing: they're not looking to begin with.

- almogo 9mo agoDoes anyone know how Iranians are _actually_ communicating right now? I remember seeing here on HN (admittedly a long time ago) some Bluetooth-mesh technologies that promised decentralized solutions to these very type of problems
- BurningFrog 9mo agoThe only working communication I see mentioned on X is Starlink.
- Imustaskforhelp 9mo agoI think IPv4 services are still present no? So like they are very heavily DPI censored though and maybe govts able to spy on any messages you send right now but I feel like there is a still possibility that for the average communication, they might still exist but although heavily heavily censored/bad and I feel like protestors might not be able to communicate (which I feel like is the question you meant to be asking) https://radar.cloudflare.com/routing/ir https://radar.cloudflare.com/routing/ir So TLDR: protestors must have a hard time sadly and they may be using bluetooth mesh or other tech, only they can tell after we figure things out but also lets say some major services websites might still exist after all if they bypass the dpi censorship for IPv4 services. In my opinion, I feel like Protestors must be using mesh based technologies as you mention. We'll see what really ends up happening after we get some reports from Iran.
- tucnak 9mo agoIt is said they pulled the plug for all peering on Thursday, although I would assume some kind of government-run ISP may be operational still (I haven't checked Cloudlfare radar)
- Imustaskforhelp 9mo agoPardon me but can you please provide me more context regarding it. I am genuinely confused about the ground state of reality in Iran right now regarding Internet access at all can you please take a look at cloudflare radar and see what the current ipv4 connectivity means? Even Ipv4 was blocked for sometime but then it got back to normal in the graph shown in cloudflare radar Can you please tell me what you mean by plug for all peering? Like complete internet blackout?
- embedding-shape 9mo agoFunny considering the top comment from the two-day old "Iran Goes Into IPv6 Blackout" (https://news.ycombinator.com/item?id=46542683 https://news.ycombinator.com/item?id=46542683): > Fortunately, the government cannot enforce complete blackout because thousands of startlink terminals are active inside the country. They have been complaining about it to no avail. Seems they finally figured out a way. Seems like yet again, you shouldn't shout hello until you've crossed the stream.
- Imustaskforhelp 9mo agoI wouldn't consider it funny though when you realize the gravitas of the situation though but yea. I just wanted to point out that it felt rude to call it funny but I understand what you mean and what intention but please be more sincere about such issues. > Seems they finally figured out a way. Seems like yet again, you shouldn't shout hello until you've crossed the stream. Someone mentions that there is a huge packet loss but its still possible. Other mentions that its possible to do this in rural villages and there are many nuances. I genuinely dont know the technological reasons or know how of what it is or what the ground state of reality is and what's actually happening but I hope that starlink still works or can have a work-around for the activists. We will see in sometime what really happens in the ground state as I must admit I still don't know if its 100% censored or what the reality is.
- embedding-shape 9mo agoThe situation as a whole is in no way funny, sorry I gave you that impression. What is funny to me, is a confidently incorrect comment from a related story just two days ago that also ended up the highest upvoted one, which quickly seemed to have been proven wrong. This is still funny to me, yet the situation itself remains helplessly depressing.
- falaki 9mo agoI left the comment on starlink on that thread. I should note some personal observations as I am in touch with a few folks inside Iran through Starlink. 1. The jamming/disruption is local to large cities most notably the capital, Tehran 2. Even in Tehran it is not complete and my friends are able to send and receive messages. Uploading videos is harder. 3. The regime is now raiding homes that they suspect have Starlink terminals. I don't know how they identify them but I do wonder if they are using technology to locate them.
- malchow 9mo agoSatellite signals are just weak RF signals and can be disrupted easily. There is nothing 'hardened' about them. It's funny that people think Starlink or any of its many incipient competitors are any different.
- Rover222 9mo agoBut it's in extremely difficult to disrupt the signals across the whole country? I person go go out with a battery and setup a starlink terminal in the middle of nowhere in 2 minutes (exactly how I'm writing this post right now from Boliva)
- notahacker 9mo agoIf your objective is to stop or at least slow coordination of protests and flow of information about things the regime is doing in the major cities of Tehran and Mashhad, you're a lot less worried that plenty of rural villages get completely unhindered signals, if anyone in them happens to have a Starlink terminal.
- Imustaskforhelp 9mo agoAgreed, the only way to get starlink terminal is via smuggling it into the country and it costs 1000's of $ or 500$ or more which is more than many months of average iranian income let alone rural villages I hope though that perhaps rural villages can shelter activists but who knows what happens in the ground level, perhaps news development from tehran doesn't reach the villages in the first case, maybe they block anyone entering and leaving the city I am not sure This seems to be a really bad development for protestors. There were reports that some protestors were killed by the govt and now I am genuinely worried about them even more. This tyranny needs to be stopped.
- Rover222 9mo agoSome videos are still leaking out and it’s likely via starlink (from what I’ve read). Better than nothing.
- 9mo ago
- anovikov 9mo agoI am wondering if Starlink users can't compensate for it themselves by transmitting a GPS signal using some SDR device locally, just putting in correct coordinates from Google Maps into it? GPS signals are at 1.5GHz which is easily accessible for cheap SDRs. But really, why doesn't Starlink device allow to simply enter coordinates manually? After all, if someone enters wrong coordinates (say to enable operation in a place where Starlink has no service), it won't work because it won't find satellites where it expects them to be. Or is there something here that i'm missing?
- deleted 9mo ago[deleted]
- DoctorOetker 9mo agoI don't own a starlink dish, but I assume one can log in and configure some things. It would be a nobrainer to have a way to enter coordinates and system time. Also the manual could have sane advice like recommendation to use "peace time" to establish the locations GPS coordinates and write them down on some sticker or so. If it can serve a basic web page with a world map, it may be justifiable to include it for the price of the dish (yes will require some flash storage).
- paganel 9mo agoGood for them, as they’re under external attack. For example a US ghoul like Mike Pompeo had this to say recently [1]: > Happy New Year to every Iranian in the streets. Also to every Mossad agent walking beside them so under those circumstances anything goes to defeat the likes of Mossad and associated foreign entities doing their thing on Iranian soil. [1] https://xcancel.com/mikepompeo/status/2007180411638620659 https://xcancel.com/mikepompeo/status/2007180411638620659
- scythe 9mo agoI think this is a major unforced error by the USG, of course we have seen plenty of those of late. There may be Israeli, American or other intelligence agencies present. But history has shown that spies can't just foment a revolution out of thin air. The Americans' first attempt at a coup in Chile, in 1970, failed. It was only after three years of US machinations and missteps by the Allende administration that Pinochet arose — Pinochet was given his fateful promotion by Allende himself! And that was in a "friendly" country where the US had many connections. Iranians wouldn't be on the streets right now if the government had listened to its own water engineers over the years. But the new political culture in our government is more interested in braggadocio than achieving real change. I doubt that if the protesters succeed that Iran would become friendly to the West. At the same time there is probably a not too contrived worry among the Iranians that Netanyahu will seize the opportunity to attack if a political transition occurs. Bluster like this only hurts the cause.
- macintux 9mo agoI have to imagine the protests would stop immediately if Iran is attacked by Israel or the U.S. You can be angry at your government while not welcoming bombers. Ordinarily I'd have faith the governments were smart enough to know better, but at this point I've lost hope.
- kyboren 9mo agoI think that depends very much on targeting discipline. If the bombs are surgically striking key regime figures and sites, hampering C2, reducing the regime's total conspiratorial power, and increasing latency in the regime's OODA loop, I imagine protestors would welcome the help. The mullahs have taken the people of Iran hostage and their goons are out on the streets killing protestors. Israel or the US metaphorically sniping the guns out of their hands would be a judicious and IMO proper application of military force. On the other hand, if the bombing is indiscriminate, or has an unacceptable error rate (oopsie, those weren't IRGC command posts, they were kindergartens), then I would expect a rally-round-the-flag effect. If the sniper misses and hits the hostage, well... people are going to be unhappy.
- ck2 9mo agoI am curious how phones now can reach LEO for enough bandwidth for voice calls but you need a full dish, however small, for starlink? Could you get at least 1mbps from a phone to LEO now for email and non-realtime data?
- bearjaws 9mo agoYou pretty much nailed it, its all about bandwidth. The emergency SOS feature is optimized down to the byte to ensure it can work with poor signal and low bandwidth.
- ACCount37 9mo agoLink budget cuts both ways. If your user terminal sucks, you can compensate somewhat - by building a larger, beefier satellite that has better antenna directionality and pumps out more transmission juice, and throwing the data rate under the bus. This is how it's done now. Having a terminal that doesn't suck puts less strain on the satellite side and, thus, scales better. But for emergencies and serving middle of nowhere, "direct to cell" makes sense.
- dsign 9mo agoMy thoughts to the Iranian people, may they get what they need and deserve at a cost that is not too high. As in all conflicts, there's always a "fog of blame" where there isn't absolute certainty about who is right and who is to blame. Though it's not that hard. Because their survival depends on it, dictators are very good at blaming others--anybody, really--for their own shortcomings, and they usually wield the kind of hard power that makes them extremely costly to topple in terms of suffering and human lives. Life is too short to have to deal with despots. We need a better, perhaps less-crowded or less xenophobic world where every person can protect their right to exist by simply packing and leaving as a last resort.

- seanmcdirmid 9mo agoI’m not against the movement, but the last time Iran had protests this bad was in 1979. It didn’t get better afterwards. It’s a huge mess and I hope they figure something out to fix it, but I’m just pessimistic.
- Rover222 9mo agoThanks for the reply. Makes sense.
- tekla 9mo agoI hope the movement succeeds. I've been curious myself about why the activist class seems weirdly quiet on this issue. On a quick scan of media feeds I've seen a couple of things that stand out (I do not confirm or deny how true these claims are) 1) Current Iran is a enemy of the USA and thus activists can't support the destruction of the current regime. Iran is able to create nukes so can put pressure on the USA in Middle East Politics (esp. Palestine and Israel) 2) The uprising and the Shah are CIA/Western Backed and thus supporting the protestors is de-facto colonialism/imperialism. 3) Contrary to popular belief Iran is not actually a Muslim nation, only the leadership is. The population is significantly more varied and people do not want to be seen supporting the firebombing of Mosques because Islamphobia. I don't know how widespread these opinions are, but it IS very strange how I don't see more outrage.
- Rover222 9mo agoI think the left-leaning activist people in the Americas are so against any position that could align with a Trump position, that they can’t think beyond those lines. If Trump supports the revolution it must be bad.

- serf 9mo agoin a country that hostile to you I would be worried about radiating any kind of EM, honestly. It's too easy to track and could cause undue targetting & victimization. my real answer : I think at that point in time effort is best spent trying to arrange escape. my technical answer : depends on the scene. directed optical/laser or microwave is very hard to track if that can facilitate the links you need -- but realistically most war-time off-grid comms historically has been established via runners, dropboxes, or community radio systems ; all options with very real inherent risks.

Maybe more practically in Tibet I had a Thuraya sat phone which you weren't supposed to have but I don't think there's much they could do about those except maybe search you.
- pbasista 9mo agoI would imagine that communicating within urban areas might be possible via some kind of a mesh network where e.g. every phone would act as a node that can forward the packets further. Something like that should be possible over WiFi I assume although I am unfamiliar with the existing protocols that would allow that. There are two main issues with such an application that I can think of: 1. Addressing. How would the nodes know where to send the packet? But I assume there are ways to deal with that which come from the P2P networks like Tor. 2. Edge connectivity. Even if it would be possible to communicate between the regular nodes of the network, those packets would not be able to reach the outside world. So, from abroad or even from the out of town, they would still appear offline. Some kind of edge bridges would probably be necessary to reach connectivity with the outside world.

- tim-tday 9mo agoIf you have the ability to jam a signal you have the ability to triangulate the source of a signal.
- smsm42 9mo agoHow it's related? Jamming is just drowning signal in noise, how does it help locating the source of the signal?
- 15155 9mo agoBecause ostensibly, whoever engineered the jammer (especially at these wavelengths) is capable of designing a capable-enough receiver.
- smsm42 9mo agoPumping out a lot of noise is usually easier than locating a source of a weak signal. That said, Russians likely have the necessary technology. The question would be do they feel like selling it to Iran and are Iranians capable of using it properly?
- 15155 9mo ago> Pumping out a lot of noise is usually easier than locating a source of a weak signal. Not at the frequencies in question - this isn't 2.4GHz where a magnetron ripped out of a microwave oven will wreak havoc, these are highly-directional, beamformed signals. Also, ostensibly, there should be zero unapproved energy whatsoever in those bands.
- smsm42 9mo agoThese things must be big, stationary and likely very sparsely manned (if anything, they must emit a lot of energy which is not healthy). If there ever were some good targets for a surgical application of some B-2s...
