3,000 from Amazon, 10,000 already approved from SpaceX, who knows how many will go up from various companies in Europe, China, India, etc... This is the beginning, not the end.

Yeah... still not enough. Millions probably wouldn't be enough. It's a really big sky.

Yup. Sattelites are roughly car sized. Think how many cars are on earth and yet cars aren’t covering the surface of the earth.

And earth orbit is an even bigger surface area.

Sounds like that plastics industry talking about disposal in the 1970's. Now look where we are.

I don’t see the connection.

Anyone wanna offer me their hypothesis on what Amazon and other tech companies gain from offering internet to people who probably aren't valuable consumers?

One of Starlink's planned markets is global high frequency trading. The latency of radio and laser transmission in atmosphere and space is much lower than undersea fiber optic cables. (Light moves significantly slower through glass than through air.) Even with the longer distance and retransmission they stand a good chance of being lower latency across oceans than undersea cables.

This is not true as far as I can tell. HFT does not appear to be part of spacex’s strategy at all.

Not valuable? Ships, oil rigs, airplanes, remote vacation destinations (e.g. ski lodges), etc have lots of money and a good concentration of rich people with lots of money.

Yeah and there's already a lot of providers of satellite internet. But, Starlink has not published their pricing, so it's unclear how much of the market will they capture.

I live in West Virginia and have no household access to broadband internet service. (No cable or DSL available here) The square mile around me has dozens of homes with incomes above the US median. Our area is not especially rugged, but the West Virginia government is both corrupt and incompetent. We are all cheering on Starlink and this new effort from Amazon. The only question is whether 5G will get here first!

Why not use 4G? Starlink's bandwidth (price per gigabyte) is probably not going to be great.

Satellites are outside the regulatory authority of countries they operate over. They can do far more of value than merely provide Internet access to poor people.

Satellites also have to be specialty built for their purpose. You can't just take a small communications satellite, attach a small camera, and have a spy satellite. Well you "could" but it would be so crappy that it'd be useless. Also LEO satellites lose their altitude rather quickly, not a great investment for spy satellites. > Satellites are outside the regulatory authority of countries they operate over. Except th…

These would make poor imaging satellites you are correct, but what could possibly be more valuable intelligence than a global scale firehose of data. Just the metadata of packet routing across the constellation would have huge value to intel agencies.

To say nothing of the implicit value in denying an adversary access to that information.

I did the math on this. It probably wouldn't be good for hft. The highly profitable hft is done on the floor of the nyse. There's some from Boston but they typically use directed radio instead of fiber-optic. Satellites will be even slower, but maybe cheaper if you're sending date from California or Australia. But it's still probably cheaper (and more profitable) to put a machine on the floor or even just in NYC. I'm…

GP is obviously not talking about HFT on the NYT, but HF arbitrage between different global exchanges.

Who else thinks these systems deliver wireless high speed Internet faster than 5G?

Maybe, but it will probably have lower total througput due to the large size of the cells. One of the reasons why 5G is faster is due to smaller cells.

In any case there's no official data from Starlink, on costs, on speeds, total througput or almost anything (if I'm wrong on this please post links!).

High speed trading. You can send a packet faster from London to nyc via a LEO network than an underwater fiber.

Why are there people investing so much money on these things, filling up the space, just for some stupid trading. Why is humanity doing this ??

"just for some stupid trading" is one of the underlying forces beneath the success of all modern economies. Without it almost everything you buy would be more expensive.
