Sure, a US invasion of Iran would undoubtedly lead to good things. And how can you say the Kurds are friends of the USA (I'm presuming you mean friends of the USA) given how many times they've been abandoned? Just take a look at what happened to Libya, sometimes removing a "bad person" will cause a far worse situation to evolve. Like literal human slavery. I will never cease to be amazed at the amnesia that arises wh…

You also forget how panama Germany, Japan, South Korea are better now after removing their authoritarian regimes.

Unfortunately, that was 75+ years ago and all the more recent examples were disasters as of my knowledge.

Where are the ground stations Iranian traffic is using? Starlink usually lacks the bandwidth to tunnel traffic very far. In most countries the ground station is in the same country. My bet is, a neighboring country, within reach of Iranian missiles. Oman and Turkey are listed but that data is old. But its not about censorship in the usual sense really. Its about preventing peer to peer communication. With less than a…

yes

Can't wait for a certain dictator to get a cellmate, so that our Persian and Kurdish friends can have freedom, including free unrestricted internet access. And for fellow HN users from there, here's some great stuff: https://yggdrasil-network.github.io/ https://bitchat.free/

how does Yggdrasil work if ipv6 is dead?

It forms its own IPv6 network separate from the internet. It can peer over any IPv4 or IPv6 network, including the internet, LAN, or PTP.

Yes, but it is more difficult than jamming a typical radio antenna because the starlink uses a directed beam rather than a omnidirectional radio broadcast. This either requires enormous amounts of power, targeting the satellite itself with a directed radio beam, or getting between the satellite and the ground station by bouncing a signal off the ionosphere. The above is for jamming directed beams in general. It is li…

Just to add more details. Beamforming is essentially yet another way to achieve gain, just like one does with a directional antenna. The Starlink terminal achieves a gain of roughly 33 dB, which means it talks (and also listens) in the peak direction at power levels that are around 2000x higher than what one would achieve with isotropic antennas. 2000x sounds like a lot, but it is actually not impossible to reach. Co…

This assumes you're jamming very close to the dish. The trouble with jamming is you have to deal with the inverse square law so you really can't deny very much area. If they have a fleet of hundreds of high power modern directional jammers they could degrade this or other networks, but they're just not going to have that kind of sophistication.

It worked out poorly for America — we got stuck in a long expensive war that we got basically nothing from — but for the average Iraqi? I'd much rather be an Iraqi citizen than an Iranian one, and that wouldn't have been true in the 90s. Saddam was pretty evil — and a bad leader. Iraq's GDP per capita is 6x higher today than it was in 2002, a year before the invasion.

It worked out pretty poorly for the average Iraqi. Hundreds of thousands of Iraqis were killed (some estimates put it at around 1 million), and millions of people became refugees. Citing the relative GDP per capita number is reductive and doesn’t give a good picture of the average person’s life.

The GDP should be banned as a metric for being a life quality proxy, it's insane how so many people still refer to it although proven to neglect so many parts of what counts into LQ. To OP: Go check out Doughnut Economics - the book does a good job clearing up economical fallacies & mismodelling of such things.

They are almost completely inaccessible to the average Iranian. A friend of mine who has come a long way to fight Iranian censorship told me that they essentially don't exist.

They must be smuggled inside the country and the dictatorship can say anything they want and charge if they get caught so they must be very few in numbers I don't know too much about starlink but is there a way that someone can pay for other person's usage and then build a starlink receiver or something from spare parts or like easy accesible parts from the world? Because how would people get starlink device. I dont…

Starlink receivers aren't built out of common readily available components. It's fancy RF stuff.

Huge idiot here with an honest question: with starlink, could a rogue actor just point a bunch of high-powered lasers at the satellites and brick them?

Cheaper to launch a barrel of metal trash to the Starlink orbits. Or a few barrels. Iran has rockets for that.

There are 9400 active Starlink satellites & they can be launched 28 at a time on a partially reusable rocket. The orbit they operate on is largely self cleaning due to being quite low. The satellites operate in many planes and bands + form a mesh network with laster interconnects.

Sure, if you want to try that and bankrupt Iran even more via its militarry rocket program, you can do that and maybe destray a handfull satellites, provided you can actually hit them and the rocket/s does not fail. And you might even get a nice casus belli as a free extra.

Iran does not have that capability. But that would also be an act of war.

Flinging spacejunk pollution into orbit is extremely simple if you have rockets. Iran has lots of rockets. Iran also has basically zero of their own satellites in orbit that they care about. Spacejunk is a highly asymmetric tactic.

They don't have that many rockets that are capable of orbital flight let alone an ASAT capability.

Imagine trying to hit a specific speeding car by throwing a dart from another moving car, except Both cars are invisible most of the time. They’re moving 17,000 mph. The dart has no steering wheel only tiny nudges. If you miss by a few feet, you miss by miles.

Countries that can do this reliably aren’t showing off missiles they’re showing off navigation, sensors, computing. The weapon is the least impressive part.

Can you provide a source for this claim?

Start here: https://en.wikipedia.org/wiki/Starlink_in_the_Russian-Ukrain... Scroll down to Russian use. Starlink receivers have been found in use in drones by both sides in the war. There's a lot of Open Source intel on this.

I guess it is to a degree unavoidable - ukrainian units are using a lot of crowdfunded starlink terminals on the front, so even if you geo fenced usage only to the virtual cells outside of Russia controlled territory, you would also disable ukrainian sets at the front. So if Russians smuggle sets from other countries, they might not be really easy to tell from the "good" sets crowdsourced by the ukrainians and used at the front.

As for use in long range strike UAVs I'm sure ukrainian units have specially registered units that will work anywhere but again, Russian long range kamikaze drones you have a smuggled unit that only activates once on ukrainian territory and be used for terminal guidance or reconnaissance. By the time the system spots a new terminal moving quickly in the wrong place the thing would have rammed into a civilian building somewhere.

Isn't it possible to jam the starlink receiver?

I've got to think it's easy to find starlink receivers--I know they use a directed beam but they must give off a bunch of lateral noise, right? Or does Starlink use the same frequency bands as other common equipment such that it would be difficult to distinguish starlink signals from others? If the government was motivated they could surely start finding these receivers, right?

I read the satellite has an omnidirectional antenna?
