The constellation of satellites built and operated by SpaceX and OneWeb is poised to fundamentally change how we access the internet and where we connect to the grid. On the surface, these two Internet services may appear to be competing, but in reality they are not.
Astronomers could be alerted immediately when SpaceX satellites threaten visibility
Saturday, March 25th, The Indian Space Agency has successfully delivered 36 OneWeb satellites to low earth orbit.raises the total constellation to 616 functional units, according to statistics Compiled by Harvard-Smithsonian Astrophysicist Jonathan McDowell. The London-based company says the first phase of the project has been completed, and global service coverage will be available after several preliminary tests. before the new year.
OneWeb is one of a constellation of Internet satellites in operation or in development, most notably SpaceX’s Starlink. Although both companies are building a constellation of Internet satellites in low earth orbit to provide low-latency, high-bandwidth Internet communication services to every corner of the globe, their target markets are not the same. And while the newer OneWeb has only a few hundred satellites in orbit, the more established Starlink boasts thousands. However, it’s important to realize that OneWeb is just the beginning.
What is Starlink?
Elon Musk may be a huckster who doesn’t disappoint and an egomaniac who ruins Twitter, but he’s not the type to waste good opportunities. His CEO of his SpaceX with his own rocket company is building an internet satellite constellation by mass launching satellites at affordable prices to reduce or completely eliminate the internet his dead zone around the world. Started the process of elimination. So, in addition to being an aerospace company, SpaceX is now a satellite manufacturer and internet service provider as well.

space x announced The 2015 Starlink project has the express purpose of addressing underserved areas of the world.At that time, Musk Said: “We’re going to do with satellites what we did with rockets.” addition Profits from Starlink will be used to fund his plans to colonize Mars.
How does Starlink work?
Starlink satellites connect directly to flat user terminals, giving customers direct access to the Internet whether they’re in their home, RV, or campsite. For US users, the service currently costs about $110 per month. Standard hardware to support connectivity is $599,The performance version is priced at $2,500. It’s not cheap and this product may not appeal to everyone.
T-Mobile recently partnered with SpaceX To provide customers with text coverage both inside and outside T-Mobile’s network. Eventually we plan to include voice and data coverage. However, for this to work, SpaceX would have to equip his Starlink satellites with a direct cellular system, which still requires FCC approval.
Scientists use Starlink when conducting fieldwork. Antarcticaand it is proven usable In Ukraine’s struggle against the invasion of Russian troops.Starlink is Note Either the US Department of Defense and China, with the latter seeing it as a potential security threat.
How many Starlink satellites are there?
Since 2019, the Falcon 9 rocket has been steadily adding to its constellation, Over 50 Starlinks per launch. SpaceX currently operates her 3,867 Starlink satellites in low earth orbit. according to to McDowell.The company has a Federal Communications Commission permission It will launch 4,408 Ku-band spectrum satellites and 7,500 second-generation V-band satellites. The latter operates at altitudes of 326 to 332 miles (525 to 535 kilometers) above the surface. To date, Starlinks operate at altitudes of 211 to 382 miles (340 to 614 km), which is generally very low and technically very low for being a communications satellite.
the company is still Pending FCC approval We hope to deploy the remaining 22,488 Gen2 Starlink satellites. In December 2022, the FCC announced that it will “protect other satellites and terrestrial carriers from harmful interference, maintain a safe space environment, promote competition, and protect spectrum and orbital resources for future use.” It said it has postponed a decision on the remaining units because order approvalThe huge size of the mega constellation is concern From astronomers worried that bright satellites pose a threat to science.
The process of bringing the upgraded Gen2 satellite into orbit has been postponed as a result of delays in SpaceX’s Starship mega rocket. Falcon 9s can’t carry his oversized Gen2s into orbit, so the company meanwhile v2 miniThe first batch went to space earlier this year, but I seem to have a problemit’s a given, Mr. Musk said.
What is OneWeb?
Founded in 2012 under the name WorldVu, OneWeb began the process of building a constellation in 2020. OneWeb declared bankruptcy in March 2020 It cited the covid-19 pandemic as a major factor. The OneWeb constellation was only 10% complete at the time.company Went out of business In the second half of 2021, thanks to significant investments from the UK government, India’s Bharti Enterprises, Hughes Network Systems and SoftBank Group
The investment allowed OneWeb to continue its project, and its satellites were carried aboard Russia’s Soyuz rockets as usual. But then Russia invaded Ukraine and the project fell into chaos again. Western sanctions prompted the Kremlin to halt launches of his OneWeb satellites, refusing to return 36 OneWeb loses hundreds of millions of dollarsIn response, the company turned to SpaceX and the Indian Space Research Organization for launch services and services. not looking back, Merged with French satellite operator Eutelsat In July 2022, we will complete Phase 1 of the constellations on March 25th.
Like SpaceX, OneWeb says its satellite constellation “can deliver broadband-style data speeds to any part of the world.”[u]”Connected and underserved communities” will be able to “join the global community for the first time through OneWeb systems and connectivity solutions.”
However, unlike SpaceX, OneWeb does not sell its services directly to households.the company instead Seek partnership With telecommunications carriers, Internet service providers, and other organizations (whether businesses or homes) that sell Internet services. So while you may never deal directly with OneWeb, your ISP may eventually choose to take advantage of the OneWeb network once it becomes available. In fact, OneWeb already has a deal with . AT&T in the United States.
OneWeb CEO Neil Masterson doesn’t see Starlink as a pure competitor, given the company’s B2B model and focus on enterprise customers. “I think there are some areas in which we compete, especially when it comes to serving governments, but governments buy multiple services all the time,” Masterson said. Said CNBC in March 2021.
OneWeb plans to make its platform available in four major sectors: aviation, shipping, enterprise and government. “I think there are multiple players who can successfully address their market,” Masterson told CNBC. He added: “We provide fiber where there is no fiber.”
OneWeb’s potential competitors include Omnispace, AST & Science, and Amazon’s upcoming mega-constellation, Kuiper.
How does OneWeb work?
OneWeb satellites are built by the aptly named OneWeb Satellites. OneWeb Satellites is a joint venture with European aerospace company Airbus. The satellite currently operates in 12 orbital planes, with 49 units in each plane and no reserves. The company’s terrestrial network consists of his 50-70 gateway sites located around the world. Client companies connect to satellites using OneWeb end-user terminals. A terminal consists of a satellite dish, a receiver, and a Customer Network Exchange (CNX) unit. CNX connects user terminals “to customer networks, and customer networks connect to end-user devices such as laptops, smartphones and sensors.” according to to Canada Satellite.
OneWeb satellites operate in higher orbit than Starlink, operating 750 miles (1,200 km) above the ground. Yet both OneWeb and Starlink operate far above the ground than conventional geostationary communications satellites, which operate at a distance of 22,370 miles (36,000 km) from Earth. The proximity means low latency, so your favorite websites and apps load quickly and smoothly.
For OneWeb this translates to: latency Less than 100 ms across the network speed Approximately 200 Mbps or higher. space x Claim Latency is 25-50 ms, and expected download speeds are 20-250 Mbps, depending on the package and other factors. Having said that, Not everyone gets great service with Starlinkthe service is deceleration As your user base grows. Hence SpaceX’s insatiable hunger for more satellites.
Speaking of which, OneWeb doesn’t stop at 616 Ku-band satellites.In Phase 2, the company will Plans to deploy 6,372 satellitesincreasing the total satellite constellation to 7,000 units from the 48,000 proposed in 2020.
Another similarity between OneWeb and SpaceX is that it’s not the only game in town. The new race for space is a result of affordable access to Earth orbit, and other companies are thinking along the same lines. Amazon’s Project Kuiper, Iridium Certus, Telesat, Facebook Athena and Alphabet Loon are also vying for a piece of the megaconstellation pie.
Which companies will succeed and how these services will improve our ability to access the Internet are open questions, as will the impact of these satellites on astronomy.
