@BTGroup & @OneWeb are discussing ways of collaborating to connect the remotest parts of Britain to broadband. The companies are in the early stages of studying how to reach homes that are too expensive to connect through terrestrial infrastructure.

Bharti CEO Mittal says in @bbcworldservice interview that first phase to complete @OneWeb is expected to cost $2.3-2.4bn (Headphone11:34). Company to "be in reasonably good financial shape by 2023/2024" as customer base grows, will make huge impact on society.

36 OneWeb spacecraft arrived at Vostochny

02/26/2021 18:10

36 new spacecraft from OneWeb, owned by the British government and the Bharti Global group of companies, arrived at Ignatievo airport (Blagoveshchensk) on an An-124-100 aircraft on Friday, February 26, 2021. Specialists of the Vostochny Space Center (a branch of the Center for Operation of Ground-Based Space Infrastructure Facilities, part of the Roscosmos State Corporation) delivered all 36 vehicles to the cosmodrome. Tomorrow, February 27, they will begin their preparation for the launch scheduled for March using the Soyuz-2.1b launch vehicle with the Fregat upper stage.

Glavkosmos (a subsidiary of the Roscosmos State Corporation) provides for the launch of OneWeb satellites using Soyuz-2 launch vehicles under contracts with the European supplier of launch services Arianespace and the Russian-French company Starsem in close cooperation with other enterprises of the State Corporation Roskosmos - by the Progress Rocket and Space Center, the S.А. Lavochkin and TsENKI.

To date, the constellation of OneWeb satellites in low Earth orbit numbers 110 spacecraft, with hundreds of others planned to be launched. The upcoming launch should bring the number of OneWeb spacecraft in orbit to 146. Low-orbit OneWeb spacecraft are designed to provide terrestrial consumers with high-speed Internet directly via satellite communications.

Vostochny continues to prepare for the launch of the second batch of OneWeb satellites

03/02/2021 16:17

At the Vostochny cosmodrome, intensive preparations are continuing for the upcoming launch of the Soyuz-2.1b carrier rocket with the Fregat upper stage and a new batch of OneWeb spacecraft. On March 1, 2021, a special board with ground support equipment and two dispensers of a foreign customer for devices arrived at the Ignatievo airport in Blagoveshchensk.

Specialists of the Vostochny Space Center (a branch of the Center for Operation of Ground-Based Space Infrastructure Facilities, part of the Roscosmos State Corporation) accepted the cargo, provided support for unloading, installation on vehicles and equipment transportation to the technical complex of the Vostochny cosmodrome. The employees of the branch also unloaded the blocks at the warehouse. The dispenser is an integral part of the spacecraft - it is a transitional link between the upper stage and spacecraft.

The day before, the second batch of spacecraft from OneWeb, owned by the British government and the Bharti Global group of companies, arrived at the cosmodrome. The technical complex is already preparing them for the launch scheduled for March 2021 on the Soyuz-2.1b carrier rocket with the Fregat upper stage.

This launch will be the second fully commercial launch from the Vostochny cosmodrome. It is being implemented by the European launch services provider Arianespace for OneWeb. Glavkosmos (a subsidiary of the Roscosmos State Corporation) is responsible for launching OneWeb vehicles using Soyuz-2 launch vehicles under contracts with Arianespace and the Russian-French company Starsem.

Currently, the constellation of satellites OneWeb in low Earth orbit has 110 spacecraft, it is planned to launch hundreds of others. The first six OneWeb satellites were launched on February 28, 2019 from the Guiana Space Center (French Guiana) using the Soyuz-ST launch vehicle and the Fregat upper stage. Another 34 satellites were launched into orbit on February 7 and March 22, 2020 from the Baikonur cosmodrome using Soyuz-2.1b launch vehicles and Fregat upper stages. In December, another 36 spacecraft were launched from Vostochny. The upcoming launch should bring the number of OneWeb satellites in Earth orbit to 146 units. LEO OneWeb spacecraft are designed to provide terrestrial consumers with high-speed Internet directly via satellite communications.

Great demos today in Florida of the @OneWeb.  satellites performance >450Mbps and <30 ms latency. Impressive.

MOSCOW, February 22 - RIA Novosti. Two additional launches of Soyuz-2 carrier rockets in the interests of the British company OneWeb may take place from the Vostochny cosmodrome this year, two sources in the rocket and space industry told RIA Novosti.
Earlier, another source of the agency in the industry said that in 2021, six or seven launches of Soyuz-2 missiles from Vostochny are planned. According to him, the commercial program foresees three launches of rockets with 36 British communication satellites OneWeb on board each, three or four launches are expected under the federal program: with the Meteor-M meteorological satellite, two Ionosphere-M scientific vehicles, the Luna-25 station and, possibly, the Kondor-FKA Earth observation radar satellite.
"At the request of the French company Arianespace (which provides commercial launch services using Soyuz-2 missiles - ed.), Two more Soyuz-2 launches with 36 OneWeb satellites in each may be included in the launch schedule," said one of the sources.
Another source confirmed this information, adding that two more launches, planned for March 25, April 23 and May, in the interests of OneWeb, may be added - in June and July. "The June start is possible with a high degree of probability, and the July start is still in question," he said.

Looks like Starlink has some competition.

This week, Team OneWeb conducted demonstrations of our network in Florida, proving our fibre-like connectivity from space with high-speeds (500 Mbps), low latency, and seamless handovers. Take a look..

MOSCOW, March 6. / TASS /. About 10 launches of the British communications satellites OneWeb on Soyuz rockets...are planned this year. This was announced on Saturday to TASS by the general director of Roscosmos Dmitry Rogozin.

"2021 - <snip>, about 10 OneWeb launches each with 36 spacecraft..."Rogozin said.

[Capacity] The north in October, the whole wide world in 2022
Quote
Sunil Bharti Mittal, executive chairman of OneWeb, says the satellite company will be completely wholesale, reaching its market only through existing local partners. It will not have its own retail arm.
...
OneWeb will launch in October 2021 with complete 24-hour coverage of everywhere between 50°N latitude and the North Pole, he confirms. That will blanket virtually all the British mainland: even the southernmost tip, the Lizard peninsula, is virtually on the fiftieth parallel.
...
In October, the rest of the world — including all of India and Africa, where Mittal’s Bharti Group runs mobile services— will have only interrupted coverage, perhaps an hour or so at a time.

But once all 648 OneWeb satellites are in service, by May or June 2022, coverage will be global. That’s the completion of what he calls “generation one” of the company’s fleet of satellites.

This puts them roughly one year behind Starlink, not too bad.

How are they achieving so much coverage and such speeds with so few satellites? I realise the higher altitude allows for larger areas to be covered per satellite, but 600 satellites vs 12000 satellites seems an excessive difference.

Also, that means they need to cover more subscribers per satellite so how do they maintain the required bandwidth to support high speeds for so many more customers per “cell”? Are their satellites an order of magnitude more powerful / capable than the Starlink sats?

What’s going on here?

The SpaceX constellation is 4400, not 12000, and 1/3 of that is just increasing density.  Oneweb will have far fewer user terminals since they're not serving individual households.

.@Arianespace and #Starsem finished the integration of @OneWeb’s satellites. See you on March 25 for our next launch! We are proud to be deploying this constellation that already has 110 satellites up there. Thanks to this kind of technology, tomorrow, we’ll all be connected.

OneWeb satellites are less powerful individually.

Also, SpaceX can do higher speeds than 100Mbps, as we’ve seen from some tests.

What's going on is that people keep treating Starlink and OneWeb like they're comparable systems. Mostly out of politeness, I think. Once ISL laser is up, it's going to be like Verizon's network compared to a handful of CB radios.
