[Forbes] SpaceX Launches First Starlink Satellites In Space Internet Battle



Quote:
SpaceX has successfully launched its first batch of Starlink satellites, a planned satellite mega constellation that aims to provide internet from space to billions of unconnected people around the world.



At 10:30pm Eastern time Thursday, a SpaceX Falcon 9 rocket lifted off from Cape Canaveral in Florida with 60 Starlink satellites on board, the first satellites designed to work within this constellation. SpaceX had launched two test satellites before, but today’s launch will be an important step towards eventually launching and operating 12,000 satellites in orbit to beam internet to the ground by the 2020s.

SpaceX is starting to build a global internet via low a massive satellite network to achieve two main goals:

1. Light travels much slower in fiber optical cables than it does in the vacuum of space. Using satellites in orbit will bring down internet latency by quite a bit.

2. To undercut broadband providers and provide something better for cheaper.

As they should be. I'm a little surprised this wasn't a topic here sooner.

errr, communication between the ground-and-sky is what kills it and this isn't just about latency either.
communication bandwidth and accuracy drops as more objects blocks the path, including clouds and smog.

so yes, while this would be a huge step forward, please don't expect this to thoroughly replace ground connection anytime soon.

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

Do you have any information to back this up?

My understanding is that the this problem was solved and resolved by astronomers a while ago and has been highly perfected since.

its not quite resolved as one might expect, they simply bruteforce through it by boosting the signal.

I don't think the point of this is to replace latency sensitive, high-bandwidth communications. For everything else, this will be fantastic.

exactly, this would be an alternative to mobile data instead of hardwired connections, specially in places that doesn't have any reliable internet connection.

in these cases, consistent low-latency connections isn't the main concern, but high-bandwidth high-availability connection instead.
e.g. you can livestream in the middle of the jungle, or you can video call someone without ever worrying about the signal, even if the connection is a bit jittery it can at least maintain connection.

For those of us that live in the boonies and have access to nothing but terrible satellite internet, this will be a godsend that cannot come online fast enough.

This is the problem SpaceX is trying to solve, but I think it will just contribute to it, honestly. The satellites use Ku and V-band, V-band to talk between each other and Ku to link down to earth. HughesNet uses Ku band as well, and V band is very unacceptable to rain fade, aka signals being "soaked up" by clouds, rain, snow, etc. I think this is gonna be a bad thing.
