I am curious if there are any implications for the Russian invasion of Ukraine from this tactic working.
Both 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.

That 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.
What are you talking about? The jammers are on the ground. Just like receivers on the ground can be jammed with bad RF nearby, so can receivers in space. You just point the bad RF towards the receiver

It seems like these smuggle-disguise protocols are almost always trivially detectable.
Does 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
I 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…

If 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.
There’s no evidence that China (or anybody else) has the capacity to meaningfully harm the 9000+ satellite Starlink constellation.
Funny considering the top comment from the two-day old "Iran Goes Into IPv6 Blackout" ( 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…
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.

Gps is free to use. Running your own gnss service requires an atomic clock and possibly separate transmission hardware, which is possible, but adds cost, volume, and weight. According to [1], “[o]ne of the current generation of GPS satellites (Block III) weighs over 2,200 kg (4,850 lb), the weight of an average pickup truck. The body of these satellites are 1.8 m x 2.5 m x 3.4 m (5.9’ x 8.2’ x 11.2’) in size”. In com…

Thanks you provide some great insights on why starlink didnt use gps but still if starlink wants to focus itself as the uncensorable internet in places like protests etc. I feel like they can probably do this after this recent incident I just c…
I’m not sure Musk would actually want that though, especially these days.
Satellite 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.
Antenna arrays aren't perfect so it still picks up some energy omnidirectionally, but it should be possible to shield it with some metal plates in a way that only sky is visible.

It 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)
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?
> 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.
