No, because SpaceX would still be an internet company.

>>10143609
No because satellite internet is crap

>Hurr durr what is latency
Granted low orbit would help with this

>>10143738
>retard using hurr durr
oh the irony
even optic fibers send signal slower than actual radio waves (and I wont even speak about regular wires)
most of the lattency happens because of server processing signals anyway

>>10143738
The distance from the ground to a satellite is trivial compared to the distance between a player in Kansas City trying to communicate with a server farm in Canada. You're just trading 1500 km of data slowly traveling through wires and through many servers for information traveling a 800 km through the air (which is faster) and then 800 km down to the target location.

>>10143609
no because ISPs will use their enormous wealth and political connections to stay in business, even if it means making satellite internet illegal

>>10143788
GEO is 36000 km high.
The speed of lught is 300000 km/s
So it takes a signal 120 ms to go from ground to the satellite. That means 480 ms ping to a server, if you use a sincle satellite, you get even more if you connect with someone on the other side of the world.
But yes, low orbit satellites have much smaller delays. Can modern antenas reach them without a dish?

>>10144322
all you need is a pizza box sized phased array unit

>>10144322
These satellites are like 350km up, so the travel time is on the order of 1ms. Latency will be almost entirely due to travel to the destination, which will be faster than any optical fibre, and processing time.

>>10144336
yep; >>10143611 mentions some of the travel time savings. Considering that HFT's paid like 3 billion dollars for a 10ms gain, 40ms will be worth a FUCKTON. There's your BFR funding, Elon.

>>10143609
>arse technica

Cool and all, but it's really just a multiple billion dollar prototype that will shape what later down the line satellite internet will be.

They're only going to run them for a few years before dropping them out of orbit to keep an impenetrable wall of garbage from forming in orbit. Even still there's a lot of unknown unknowns regarding the shit fuck ton of satellites and the logistics of dealing with them.

Most countries around the world will prevent their citizens from using that service in order to protect vital communications infrastructure and companies. Starlink is DOA.

we already have satellite internet and its slow as fuck. unless we learned how to send signals faster somehow i doubt it will be better

without developing antigravity and ftl satelite internet will never work its just too slow

>>10145046
>>10145049

once again, low orbit satellite internet is as fast as fiber, even faster for long connections

>>10143738
normally i love to shit on musk ventures but this time you're the idiot. they designed the network so latency isn't an issue, it's so good even HFT firms are eyeing it

You'd need 100+ Delta IV launches for this. Science fiction leaning mostly toward the fiction part.

>>10144340
>There's your BFR funding, Elon.
How is he so much better than everyone else (sans Bezos)?

>>10145083
>Delta IV
look at this dude hahaha

>>10143754
Uh, your bandwidth is determined by the difference between your modulating signal and your carrier, and bandwidth is the prime determinant of the actual speed of a given operation. beaming up to space introduces inherent latency of at least 100ms. More efficient routing may or may not pay off relative to hard ground based infrastructure, which has a theoertical maximum bandwidth in the terabytes per second because fiber's lowest frequency is quite high, as its range.

Many companies are trying to sell this idea that fiber isn't as good as their shit they can beam around, but it's just that, a bag of half truths, disingenuity, exaggerations, outright lies. They're selling you a bill of goods with hype and marketing.

>>10145795
wrong. Starlink will slash latencies across the board. They’ve been playing CSGO games on tin tin a and b ffs

>>10145795
>beaming up to space introduces inherent latency of at least 100ms
if you're going to a satellite in GEO, sure. that's not what spacex is doing, though

m8s....

It's a fantastic idea, if it all goes well. I currently live in bumfuck nowhere Europe and my house has been left out of the FTTH rollout. As such my only options for the next 10 years are 2Mbps ADSL or 4G connection that drops to 2Mbps at even times due to congestion. (No data caps for 4g here thankfully).
Something like this would be a godsend to many in my position. But as has been mentioned in this thread, it actually has the potential to be faster than fibre over long distances, meaning if they can prove it with preliminary tests they might get a huge investment from high frequency traders, which would just be gravy.

I just hope it manages to get of the ground before musky boi finally has his mental breakdown.

>>10145046
Current satellite internet uses satellites way the fuck out in GEO orbit. Starlink will use LEO satellites. Huge difference in latency between the two.

>>10144322
It is not GEO, it's VLEO

The constellation would be useful for other things as well. If you stick a simple camera or some off the shelf sensors on each of them, you would have 24/7 data sets for any point on the earth. Could see a lot of potential research there

Imagine these boys in super low orbit with Starlink lasers.

>>10146130
Similar situation with adsl and 4g(datacapped), so I'm buying into starlink the moment it's available. The real question is if it will be legal, and if yes, at what price as far as cost and service quality goes.

>>10146269
>>10146130
My home town was in this situation until recently. A local ISP started offering fixed-wireless service with 20down/4up for $65/mo and no caps. Not blazing fast but a hell of a lot better than 2Mbps ADSL.

I'm definitely curious about what the monthly cost of Starlink will be. It sounds great but if it's more than $100/mo it's going to be out of reach for a lot of people.

>>10146322
the autists over at NSF are estimating that pricing will be dynamic and based on the local prices in the area being serviced.
Meaning, all SpaceX has to do is slightly undercut the competition for each region. After all, after the pizza box purchase the marginal cost increase per new customer for SpaceX is basically nothing.

>>10144297
I mean starlink is already approved by the FCC and will have global coverage so what are they going to do? Make importing a starlink pizza box illegal? Lmao good luck with that.

>>10146348
nonetheless SpaceX will have to go along with countries and network regulation/region-locked pizza boxes.

>oh Elon, our citizens can access the Internet?
>no more Tesla sales for you in our country. Bye!
etc.

>>10146358
God the future is fucking depressing.

Idk guys, this is such a superior method to existing internet infrastructure that I feel like all the richfag telco companies are going to pull out every fucking dirty trick in the book to maintain their stranglehold.

>>10146348
>pizza box illegal
Well, illegal sounds too problematic and toxic. Bad optics. How about a nice license instead?

>>10146377
hmmm, I assume that each receiver will be unique? They’d have to assume that people will attempt to tap into the network without paying

Satellites ain't real. They'd be a fucking waste of time, money and effort. They are mathematically impossible, because if they had to account for time dilation, then the calculations would need to be perfect to maintain accuracy, yet far too many factors are involved (temperature, atmosphere, season, degrading orbit speed, etc) that cannot be accounted for due to its randomness, which would make GPS useless.

Makes much more sense to have land based GPS, which can use triangulation, instead of spending millions to launch a fucking rocket, and deploying something that is in danger of being hit by all sorts of things, and would be near impossible to repair.

>>10146358
He'll have enough leverage not to care. If any country tries to limit sales of his pizza boxes he can refuse to sell the technology to that government, putting them at a tremendous disadvantage.

>>10145785
Expendable launch vehicles are the only tried and true method of placing satellites into orbit.

This was never any kind of secret.

How many of these 12 thousand satellites can they jam into a FH launch?

>>10143609

>11,943 broadband satellites

That's gonna be a lot of shit floating in orbit. Don't already we have thousands of satellites in orbit too?

>>10147027
only like 4000

If they were super lucky and had no major delays what would be the best case and worst case ETA on this shit?

>>10147027
They're also in very different orbits. These would be a lot lower than any satellite we have out right now.

>>10143609
It's only profitable for low-density areas OR high-density areas in parts that have no infrastructure at all (e.g. 3rd world shitholes). It won't replace the ground-based internet for 99% of the people.

>>10147597
LEO will be a booming business globally.

Can't wait for telcos to get gassed, best day of my life.

Wow good thing that they own a rocket company that is in the process of rapidly decreasing launch costs and turnaround times and are the best in the world at vertical integration then eh?

>a massive coordinator just for them to work together and monitor them

Yeah, this is what peoples connection fees will fund along with the capital payback. Jesus you are stupid.

I'll take that as a yes
normally that would automatically discard any opinion you have about anything technically related, but since I'm bored here we go
>the whole retarded paragraph about latency
it is true that leo satellite is faster than fiber, however the throughput is absolute dogshit. current systems have 64kbit, because apparently tracking satellites moving at insanely fast speeds and constantly switching them after they disappear from your range is pretty hard


also, what the fuck happens if you're in a city like New York? you're just fucking because there isn't the technology to build an array of satellites which can sustain that many simultaneous connections, even if you combine them into pivot points of access
also, these satellites will be wasted since the rest of the orbit will be mostly nothing
>muh spacex the best
yeah, that's why they recently cancelled falcon 9 and keep reducing the BFR payload.
>muh capital payback
I think you don't exactly the complexity of a system of 12000 satellites maintaining 9 digit connections simultaneously and constantly passing them around

>>10149031
>demonstrably false
>he never had satellite TV
lmao

>>10149037
>tracking satellites moving at insanely fast speeds and constantly switching them after they disappear from your range is pretty hard

if only there was a way to make satellites geo-stationary... hmmmmmmmm

>>10149037

What the fuck are you gibbering about.

>>10149042
You can do it. You just increase your height by a factor of 72x is all.

>>10149042

>>10149045
>btw, we changed the design of the BFR for the 4th time already

>>10149051
>No longer planning to upgrade Falcon 9 second stage
>Cancelled Falcon 9

Can you even read?

>>10149052
what was the fucking point of the falcon 9 then if they can't even achieve full reusability

>>10149056
They were never planning to make the second stage reusable from the start, even the supposed upgrade was just to test re entry patterns and heatshield durability and would splashdown still. The point is to make the first stage fully reusable, third flight of F9 booster in two days, stay mad cunt.

>>10149056
advancing the BFR timeline is great. Technical debt is not what SpaceX needs.

>>10149063
SSO-A is now delayed past thanksgiving. Spaceflight is having integration check issues. 64+ satellites make integration a shit

>>10149085
>>10149063
hmmm, seems to be on SpaceX's end https://twitter.com/minxsscubesat/status/1063888514280902656

>>10149102
it's always on Spacex's end lol

>>10149120
there are customer delays all of the time. part of the reason for 2018's slight lull in launches.

But, the only delays you hear about are the once within t-5 days or so. Who cares if the payload takes five extra days to process a month before the launch?

>>10149120
SpaceX is doing the hard part.

>>10149042
>constantly switching them after they disappear from your range is pretty hard
This is the hardest part. There was some bullshit back in the 70s or 80s that tried it with radio towers and you can guess how successful that ended up being
