The idea of a constellation of satellites is not new by any means, think of previous examples like the Iridium network, or the most ubiquitous example, the worldwide navigation system GPS. There are a few big differences between these examples and the Starlink network however.

Firstly, the orbital altitude of the satellites. GPS uses high altitude MEO satellites at a height of 20,180 km, although Iridium satellites are LEO.

Secondly there is the number of units in the constellation, Iridium has 82 and GPS uses 24.

Starlink in comparison already has 895 units in operation right now, and is aiming for a first stage constellation of 12,000 units!

(Bear in mind this is just the initial phase of 1,600 for the first stage of 12,000)

This brings us to the third difference and real clincher, the cost of launching the satellites. Every other player has to pay exorbitant fees for a launch provider to send their precious payloads into orbit, which tends to put a practical limit on the number that is economically feasible. Not only does SpaceX fabricate their own satellites for the cost of a suburban house, but they also happen to have their own launch vehicles that can launch 60 units at a time for a fraction of the cost of their competitors.

When you make the most of these huge advantages that SpaceX has over the competition, you have a system that can offer huge data handling capacity that no one else can get remotely close to.


Will the Star-Link program being developed by Elon Musk change the world With Starlink internet ?

Perhaps.

It has the potential to do three things:

Provide cheap, high speed Internet to people living in very remote places. This “levels the playing field” for many 3rd world people.
Eliminate, at a stroke, the monopoly held by cable TV and traditional telecom companies in most of the USA. Right now, if I want high speed internet - I have literally no choice. It’s either Spectrum - or junk. They can charge whatever they want - provide crappy service - piss me off in any number of ways - and there is nothing I can do about it.
Provide a way for people in places where there is heavy-handed Internet censorship to break out of that. Ending this evil practice in places like China would be a very good thing.
Whether it actually ACHIEVES those things is less certain.

It may be that StarLink ground stations cannot be made cheaply enough for people in remote areas - and may not be able to compete with cellular.
With only (“only!!”) 12,000 satellites, there won’t be enough bandwidth for everyone in a large city to use it at the same time. So breaking monopoly in those places may be difficult until/unless StarLink can get up to the 42,000 satellites they’ve been seeking permission to launch.
It may be that countries which have censorship of the Internet will be able to effectively ban the import of the ground stations - or perhaps they can provide political pressure to prevent SpaceX from communicating with ground stations in certain geographical areas.
It may be that the monopoly cable networks can fight back by improving service, dropping prices and providing more service to remote areas. That might make trouble for StarLink in terms of profitability - but on the other hand, this is what we want to happen to resolve the monopoly problem without just creating a different monopoly. If cable networks were driven out of business by StarLink - that would be a very bad thing.
One important thing that StarLink *WON’T* do is to replace cellular communications for mobile phones.

There is no physical way to cram a StarLink satellite radio link into a cellphone.

Another thing is that the US Military have been doing a lot of experiments with StarLink - and seem to be happy that it could be used for their purposes.

Yet another is that financial institutions that need to do high-speed stock trading are DEFINITELY going to want StarLink because it has lower latency than fiber or copper wiring over medium to long distances.

How does Elon Musk's Starlink work? Will We be able to have Starlink internet and wifi anywhere?

When StarLink is completed with all of the satellites it needs - then yes.

You’ll be able to get service literally anywhere on the planet - except (possibly) very close to the North and South poles.

That service isn’t “WiFi” - but if you connect up a WiFi router to the gizmo that StarLink will provide (the “UFO on a stick” as Elon describes it) - then, yes you can have WiFi pretty much anywhere.

The system works by having your StarLink device send your data by radio to the nearest of several satellites that’ll be whizzing overhead at about 17,000mph. That satellite will figure out where you want the data to go - and if that destination is within range of another nearby satellite - then it’ll send your data to it via a laser beam - to that satellite - which will send the data by radio on to it’s destination.

If the destination is far away - then the first satellite will send your data to one of a fewer number of slower moving satellite in a much higher orbit - which will pass data on to another, and maybe another, and then down to a lower level satellite and then to the ground.

To minimize the amount of traffic through the network of satellites - there will be a bunch of ground stations connected to the Internet “backbone” that will hand off the communications to the rest of the Internet to handle.

Why has Russia banned the Starlink Internet of Elon Musk?

It’s really not too hard to see that Elon Musk is a thorn in the side of Russia. Up until last year, the US had spent $3.9 billion ferrying astronauts to the ISS since the Space Shuttle was retired in 2011. Roscosmos was charging $90 million per seat in their vintage Soyuz vehicle, which SpaceX are now doing for $55 million in the brand new and much more spacious Crew Dragon vehicle. This doesn’t even take into account the revenue lost from commercial resupply contracts that SpaceX has won.

One of Russia’s main income streams comes from oil and gas exports. Guess what the main objective of Tesla Inc. is? Tesla is not just an EV company, but rather an energy company dedicated to the expiry of hydrocarbon fuel use that just so happens to make cars. It’s also a company that is expanding at an exponential rate, doubling in size every 18 months, and that is a threat to the oil industry.

The Russian IT industry has been growing since the 90s, and now contributes to over 1.2% of the country’s GDP. In June 2015 the Russian parliament passed a law to establish a preference system for software developed in Russia. The Russian government is quite prepared to act to protect its domestic industry, especially from someone as catastrophic to state run monopolies as Elon Musk.
