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 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 pack…

The 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.

I 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…

I 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?

You 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.

Why not? Has Musk shut off Starlink? The reporting out of Ukraine was almost entirely wrong. https://en.wikipedia.org/wiki/Starlink_in_the_Russian-Ukrain...

Nobody brought up Ukraine

From your link, with good sources:

In 2022, Elon Musk denied a Ukrainian request to extend Starlink's coverage up to Russian-occupied Crimea during a counterattack on a Crimean port, from which Russia had been launching attacks against Ukrainian civilians; doing so would have violated US sanctions on Russia.[18] This event was widely reported in 2023, erroneously characterizing it as Musk "turning off" Starlink coverage in Crimea.[19][20] SpaceX executives repeatedly stated that Starlink needed to remain a civilian network;[21][22][12] in late 2022, as Starlink was being used as a tool in combat in Ukraine, SpaceX announced Starshield, a Starlink-like program designed for government customers.[23][21] Musk is reported to have said that Ukraine was "going too far" in threatening to inflict a “strategic defeat” on the Kremlin.[24]

Musk, like Trump, has an interesting relationship with Russia. The investigations into that have been quashed, so we don’t get to find out about the rumoured Kremlin calls he was making.

Seems 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.”"

This whole stalink for military use (Starshield) was a scam Elon sold the military from the beginning. Just like his dumb ass tunnels and his self driving cars. He is putting the military at risk.

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

The GPS satellites aren't receiving anything. The GPS satellites transmit signals, and the starlink terminals (and other users of GPS) receive those signals.

Ok they said the GPS of the starlink satellites is being jammed, and the question was how. The comment I was replying to did not say the terminal, it said the satellite. Maybe that's the confusion

I candidly thought it wasn’t possible to block Starlink. I guess with motivated actors anything is possible.

The Russians have developed rather efficient GPS jamming equip., as we know, Iranian Gov't is partners with Russians, providing drone technology, so no great mystery where likely the jammers originated from.
