It's ridiculous to need to add that many hops just to do something as basic as receive a packet from someone else on the internet.
Well, as was said, you could just pay more for the service that includes a routable IP address.
No one in Asia or Africa or India seem to be using it. Are we just polluting LEO for the sake of a handful of Americans? I feel like in the US it's not even widely used...
In India satellite services are illegal except Inmarsat because they have a deal with them for surveillance. That's probably why. You can get in serious trouble there for carrying a satellite phone too.

I believe the current implementation of the network requires the satellite to see both you and a ground station at the same time. So ground stations are the limiting factor.
It was this way until very recently, google "starlink lasers". The newer satellites have satellite-to-satellite laser links which can form a chain until they reach a satellite that is presently overhead of an earth station. SpaceX has now started selling the global ocean maritime product version of starlink which specifically advertises full ocean coverage worldwide. I recently saw a person's first hand experience of…

I believe so - its a very small niche. If I understand correctly, the target audience is: - remote places, with - people who need internet but dont have a wire or fiber running to them, and - who can afford a super expensive starlink (have disposable income), and - for who 3G/4G isnt good enough Thats not a lot of people outside the US
You don't need to be in "remote" places for Starlink to be a big benefit. My brother lives about a 10 minute drive from about a 10K person city in coastal Maine and he could not get wired Internet at all and the other wireless options are poor and data limited. There are a ton of places like that. You could argue that there should be a program at the national level to get wired Internet to anywhere that gets electric…

> Are we just polluting LEO for the sake of a handful of Americans? I feel like in the US it's not even widely used... It is quite popular in Ukraine. Granted, Ukraine is neither in Asia nor in Africa.

They will. This technology will do a lot to bring the internet to low index of development countries. It's pretty cool to think about the impact of all the kids who will go from no access to having the world at their fingertips.

That's interesting-- I didn't know this.
China's another one that doesn't permit them. Which, together with India, means that the majority of the world's population lives in countries where they are (mostly) banned.
I wonder what's going to happen now that sat features are becoming ubiquitous on mobile phones. Apple has it (with Globalstar), Motorola/Bullitt is introducing it right now (with Inmarsat), and Qualcomm is introducing the features in Q3 this year (with Iridium)
This means that banning sat phones will no longer be as easy as it once was, as most visitors will carry one right in their pocket.

Bullshit. Space is definitely 3D and has 3D packing. Starlink is at about 550km. That has an orbital period of 1.5917hrs. Satellites are 7m (as suggested above, but this sounds large). So let's space the next group by 10km. Now the orbital period is 1.5952hrs. We have to go to 580km (+30km) to get to 1.6hrs, which is a difference of 37 seconds. So you got 60km (520km-580km) where you have an error rate of under 1% (0…
The problem with your model is all orbits at a given altitude intersect. You can orbit at the equator, or orbit above and below the equator thus crossing the equator. There’s nothing special about the equator here. All polar orbits meet at the poles, and any non polar obit is forced to cross all polar orbits etc. In practice this is not be a significant problem because you can pack a great deal of satellites at a giv…
> In practice this is not be a significant problem
Which is really why I didn't bring it up. We didn't even talk about eccentricity. My model is simple but this is HN, so I added magnitudes of error.

> People don't invest into supporting things the instant they release. Virtually every other aspect of the tech world, including networking, has managed to update multiple times in the intervening years. We don't (mostly) use dialup; we switched from 2G to 3G to 4G and now to 5G mobile telephony since then; HTTP has been mostly deprecated for HTTPS and the cryptography standards for the latter have changed; etc. > Wh…
>has managed to update multiple times in the intervening years. Not fully though. There is typically some amount of people who still haven't updated and at name point you just end up ending support for them. >we switched from 2G to 3G to 4G and now to 5G mobile telephony since then; HTTP has been mostly deprecated for HTTPS These solves real problems for consumers. IPv6 doesn't. CGNAT has turned out to be good enough…
Apart from the problem of "we literally can't have all of you online at the same time in v4, y'all have too many devices".
Not that normal people should have to care about CNAT vs IPv6, but you act like the correct solution is an unacceptable horror story and the sticky plaster is panacea.

Huh. I wasn’t worried before reading this thread. Now I’m a little more worried. 1. We don’t need to worry about Kessler syndrome, as the orbits of Starlink will decay in five years (from 550km). 2. ISS is at 420km. Has anyone else ever worked with something dangerous dangling over their heads? It’s kind of nerve wracking, even if you know that there’s very little chance of it falling and hitting you.
Are you afraid of airplanes flying overhead? Probably not. These don't burn up in the atmosphere and when they fall they do a ton more damage than satellites that don't. A big reason you're not afraid is because the chance of you (or any person) being hit is pretty small because the object is so small compared to the potential falling area. Now we're talking about objects that are significantly smaller than airplanes and with a potential "falling area" (if somehow something doesn't burn up) is magnitudes larger and into an area that is basically empty (humans don't even occupy 15% of the surface).
You shouldn't be worried. Even if parts of these things were hitting the ground they wouldn't be that dangerous just due to the statistics of being hit. Odds get even better when we talk about typical orbits.
