Elon Musk Enters In-Flight Wi-Fi Market With Small Satellites (bloomberg.com) 40
SpaceX wants to show the world its Starlink satellite system can deliver Netflix and YouTube at 30,000 feet. So it recently held a demo for the media aboard a jet operated by its first airline customer, regional carrier JSX. From a report: The short jaunt from Burbank to San Jose, California marks the start of Elon Musk's bid to seize in-flight business from satellite providers Intelsat and Viasat that already serve thousands of aircraft. It won't be easy, even for a serial market disrupter such as Musk.
"Are they a serious competitor? Yes," said Jeff Sare, president of commercial aviation for Intelsat, a leading provider of wireless service on airlines. Still, Sare said, "We don't believe there's anybody that can beat us." Starlink, part of Musk's Space Exploration Technologies, delivers broadband from a constellation of low-flying small satellites. Lower satellites circle the planet in 90 to 120 minutes. That's a departure from the established practice of using a few powerful spacecraft in higher and slower orbits. An upside for Starlink is its signals arrive sooner.

First hop latency of 30 msec is "ultra low" for satellite internet as vs typical 600 msec. 30 msec is fairly good for terrestrial wireless services in my experience.

Reduced latency is a benefit, but not the main concern. If the satellite orbit is lower, it will cover a smaller surface of Earth, and will serve less subscribers. Of course it will require way more satellites in the constellation to cover all the surface, but the number of customer devices per satellite will be lower and, thus, their individual throughput will be higher.
Of course, this will depend on the eventual number of customers served by SpaceX; but in general a much larger constellation in LEO orbit scales much better.

But do they have to be LEO?
What is preventing "traditional" providers like ViaSat from increasing the number of satellites and thus the throughput?
Is it just cost, or is there are there technical reasons, too?
Re: (Score:2)
That said, LEO does require far more sophisticated technology compared to geostationary because the ground-based antenna has to be able to track the LEO satellites as they move across the sky, which is accomplished using a phased array antenna. Those were used exclusively by the military and for research until quite recently. I do

Sure you could definitely put your comsats higher and have them be larger/more numerous. But as your orbit increases in height so does the launch/satellite costs, and with satellite/launch costs historically being in the hundreds of millions of dollars the subscription costs were always going to be high. SpaceX kind of changed the metrics, first with much cheaper launch costs. I would wager that internally they pay less than $25 Million per launch (Musk claims $15m per launch but that probably doesn't in

The premise behind the old satellite system was that you charge outrageous prices and don't improve, because you're collecting your monopoly rent.
The problem medium term is the old guys have no real way to compete with SL...and once they start losing contracts they lose financial viability. It only takes one contract loss for the death spiral, because at some point you need to cut staff because expenses...but then you don't have enough staff to do new things, etc.

Most of them are not competing with Starlink. They sell services to other businesses, with things like guaranteed bandwidth and availablity. They don't oversubscribe the system used by aircraft to communicate important diagnostic data, for example. They target markets like IoT sensor networks where the requirements are very different, e.g. 130W for the transceiver is not acceptable.
Most if them are not doing in flight internet access. The ones that are, yeah, they are in trouble.

No, I'd imagine quite the opposite — an almost-octagenarian in combat fatigues shouting "Help me liberate you from the king!" while running down the beach with a crazed look in his eyes — and I'd laugh for a minute or two before concluding that you must have meant the U.S. military and wondering why you didn't say that in the first place.
If you mean SpaceX, say SpaceX. Attributing the work of a company or government or military to a single individual is hero worship, not journalism.

The hard part of most things isn't the actual literal engineering it's finding a way of making it cost effective. "Going to Mars" would be easy if you just devoted a few trillion dollars.
Everybody says "Pfffttt, Elon didn't do anything" and yet somehow magically no other company is doing what Elon is doing. "Pfft, Electric cars are easy" Ok... and yet Tesla is selling 70% of EVs in the US.
High level engineering is engineering. Every level of engineering is engineering. Engineering mostly comes down to narrowing the infinite possible design space to a single functional solution. There are infinite possibilities and infinite balancing of tradeoffs with any solution. The guy working on the valve that opens and closes is solving the exact same problems as the guy who chooses which valve to greenlight.
Elon is a covid denying, 4chan edge lording, douchebag. But he's also proven that as a high-level engineer he's very good at his job. The reason Autopilot is the defining feature of Teslas is Elon Musk. The reason automatic windshield wipers and auto high beams are unusable embarrassments on a Tesla... is because of Elon Musk.
"SpaceX is doing this not Elon Musk" is such a classic idiotic Slashdot comment that thinks that the engineer who designed a valve is the reason SpaceX is SpaceX and Boeing is Boeing. Ignoring the significance of not just Elon Musk but also Gwynne Shotwell is just a way to protect your own fragile ego and significance in an organization where you probably are easily replaceable, and the company would never notice if you disappeared.
I'm not saying that companies can't create products without workers. Collectively workers are important. But workers all independently fucking around don't achieve anything without direction and purpose and someone saying, "This is what we're all going to be doing."
You might as well say "Steven Spielberg isn't a film maker, he just told people what to do." Exactly. Telling people what to do is the whole fucking point of leadership. Yes, it's super collaborative. No, that doesn't mean every idea comes from the top. But the person sorting through 300 or in the case of SpaceX 10,000 people's ideas is A Job. It's a difficult skill. And when you suck at it, you end up like Boeing or GM or Ford or ULA or Blue Origin or [insert company here] who had as much or more money than Elon but for some reason failed to do what Elon's companies did.

He's the hype man. Starlink is already having contention issues in some areas where they took on too many subscribers.
He talks about YouTube, but the bandwidth is split between hundreds of people on the aircraft. So either it's going to be priced high enough that only a few people use it, or it's going to have issues.

A physically moving dish antenna only works for geostationary satellites.
Low-orbit satellites like Starlink move too fast for that, plus you need to switch between satellites frequently.
So it always uses a phased array antenna. They may still have servos to aim in in the right general direction for optimal reception.
