Planes (nominal): 12 spaced 30°
Planes (actual)..: 24 spaced 15°

Actual there are or will be 12 planes spaced by 15°. And with that, the earth is covered.
That wording is strange alright. For those of us who didn't immediately visualize Earth coverage based on this spacing, remember that all 12 planes are very nearly exactly polar. The satellites all operate for the full orbit, so they operate when traveling north to south and again when traveling south to north, so there are 24 coverage strips. That's why 12 planes cover the whole 360 degrees.

There is a tiny little gap between one particular pair of planes because the orbits are not at exactly 90 degrees of inclination. If I recall correctly the gap is widest at about 45 degrees latitude and everybody at that latitude is under the gap once a day.

What do we know about the business model for OneWeb? Will it be direct to user, like Starlink? Any word on ground terminal equipment or end user costs?

OneWeb service will be offered through distribution partners.  Here is a SpaceNews article comparing and contrasting OneWeb and Starlink distribution strategies:

And here is a press release from OneWeb about an order for 10,000 terminals made by Hughes Network Systems.

OneWeb to Deliver Remote Community Broadband in Trials for UK Government Connectivity Programme
OneWeb’s high-speed, low latency LEO network will deliver connectivity for trials through its partners BT and Clarus.

White City, London – 11 April 2023: OneWeb, the low Earth orbit (LEO) satellite communications company, announced today that it has been selected for two trials to connect remote communities for the UK government’s Very Hard to Reach Premises connectivity programme, which aims to connect the UK’s most remote homes and businesses

As part of the programme, OneWeb’s high-speed, low latency LEO network will deliver connectivity for trials through its partners BT and Clarus. Trials will take place in the Shetland Islands and on Lundy Island, near the north Devon coast. These trials build on OneWeb’s strong track-record of delivering community broadband to sites in remote locations such as Canada, Greenland, and soon to British territories in the South Atlantic.

Michelle Donelan MP, Secretary of State for Science, Innovation and Technology, said:

“Our Wireless Infrastructure Strategy sets out our plan to ensure everyone, no matter where they live, can reap the benefits of improved connectivity. With the help of companies like OneWeb, we are committing £8m to provide satellite connectivity for our most remote communities so that no one is left behind, while ensuring all populated areas in the UK will be served by what I call ‘5G-plus’ technology by 2030.”

“This package of measures turbocharges our progress towards becoming a science and tech superpower with a substantial initial investment in the future of telecoms.”

Neil Masterson, CEO OneWeb, said: “We are excited to demonstrate the impact of LEO connectivity through these trials. From the beginning, OneWeb’s mission has been to bridge the digital divide for communities, but there are still countries around the world where reliable access to connectivity is unattainable. Working with the government, alongside our trusted partners and customers, OneWeb can help to bring connectivity to the communities and businesses that need it most, in underserved regions in the UK and around the world.”

Having recently completed its 18th launch, OneWeb now has a constellation of 618 LEO satellites, enabling the roll-out of global coverage later this year. This enhances OneWeb’s existing connectivity solutions, which are already live in regions north of 50-degrees latitude and delivering connectivity to previously unconnected and underconnected communities, businesses and local governments.

OneWeb has 400 staff today based in the UK, the majority of which are in STEM roles, making a significant contribution to the upskilling of the UK economy and building a new industry in the UK.

Investors still have no confidence in Eutelsat+Oneweb.
The value of the Eutelsat share is falling and falling and falling, since the merger was announced.

The value of the Eutelsat share is falling and falling and falling, since the merger was announced.

The merger was in July 2022, where the stock took a 33% hit. Anything after that looks like random noise and follows the general decline of Eutelsat stock during the past five years.

The Eutelsat share collapses in spring 2020 at the beginning of the Covid pandemic. Like SES, for example.
After that, Eutelsat saw a slight upward trend in the long term, until the announcement of the merger with Oneweb, since then the value has been steadily falling.
Eutelsat has made major efforts to reduce its debt over the past 10 years. A long difficult way.
The merger with OneWeb contradicts this course.

OneWeb Enterprise Partnerships Press releases

23 May 2023
Arctic Space Technologies to support OneWeb’s constellation with construction of hyperscale satellite ground station installation

New OneWeb Satellite Network Portal (SNP) will be constructed at Arctic Space
Technologies’ Space Centre in Piteå, Sweden

Piteå, May 22, 2023 – Arctic Space Technologies, the highly sustainable and innovative ground segment provider, and OneWeb, the low Earth orbit (LEO) satellite communications company, announced a leap forward in the construction of the OneWeb Satellite Network Portal (SNP), a hyperscale satellite ground station installation at the Arctic Space Technologies’ Space Center in Piteå. The companies signed a bilateral agreement in December of 2022, and have now finalized the detailed design work as well as obtained all approvals for the construction of the SNP. Under the agreement, 27 satellite tracking antenna systems will be installed and are expected to be operational in Q3 2023.

The SNP will provide increased connectivity for customers across industries including maritime and aviation, as well as meet network demands and provide 4G and 5G backhaul solutions.

OneWeb’s decision to expand its reach in this region is a testimony to the benefits of the massive investments into sustainable energy currently being made in Northern Sweden. For example, the combination of the sustainable focused EcoDataCenter, used for data processing, the zero-carbon Arctic Space Center for Ground Station operations, and OneWeb satellites could render this project into one of the most ecologically friendly propositions in the market.

Stephen Graham, OneWeb Director for SNP Site Management, said: “We are delighted to partner with Arctic Space Technologies to construct a satellite network portal in Northern Sweden. Alongside the completion of our global LEO constellation, the development of a distributed and sophisticated ground infrastructure is critical for OneWeb to deliver connectivity for customers across a range of sectors. Our expansion into the Swedish market has been shaped by the benefits of working with strong local partners alongside the technological and sustainability credentials of the Arctic Space Center, both of which will help deliver OneWeb’s mission.”

Benjamin Fischer, CEO of Arctic Space Technologies is excited about the relationship: “It comes naturally that we work together with a company like OneWeb to support with sustainable hyper scale satellite data processing capabilities to meet their rapidly growing demand for network bandwidth. We are happy to be able to share the benefits of northern Sweden with partners like OneWeb, and I look forward to our future work together that will not only be of great benefit for both parties, but also align space activities with the European Green Deal. In addition, we currently rapidly expand our support for satellite constellations worldwide and by the trust of companies like OneWeb, Arctic Space Technologies continues to build up momentum and innovate the market to bring forward new standards for satellite data processing” he says.

“Responsible space is a top priority for OneWeb, which is why we are pleased to partner with them to create sustainable, innovative solutions on the ground. Together, we will help bring OneWeb’s high-speed, low-latency connectivity solutions to the Northern Sweden region, marking another important step forward in closing the digital divide.”

The Arctic Space Center was taken into operations in 2021 has since then has been growing into one of the largest satellite communications facilities in Sweden. Arctic Space Technologies is currently in a state of rapid expansion in terms of employees, facilities, and services in addition to the growing customer segment. “Operating from the coastal region of Northern Sweden has shown to be not only beneficial from an environmental point of view, but also in terms of lower maintenance and operations costs, great fiber connectivity, a milder climate, easier to retain staff, and the satellite coverage extends seamlessly from the Arctic to Europe and North Africa. It would be foolish to not offer these advantages for partners such as OneWeb”, says Benjamin Fischer.

We have signed a new deal with @Telstra, confirming that hundreds of existing remote mobile base stations that use satellite backhaul will be moving to OneWeb’s LEO network this year 🛰️

This will be one of the largest rollouts of our LEO backhaul for a commercial mobile network.

So that is taking all Telstra's satellite cellular backhaul off Optus (GEO satellite) onto OneWeb (LEO).
For Telstra this is a win-win: not just better customer service through much lower ping times; but also taking revenue off a competitor (Optus) and giving it to a non-competitor (OneWeb).
With Starlink mowing through NBN's "Sky Muster" remote Internet access customer base - also an Optus GEO product IIRC - the future financial viability of the GEO satellites must be very doubtful.

Intelsat’s agreement with OneWeb does not cover a second-generation constellation that Eutelsat is jointly considering with the LEO operator for deployments as early as 2025.

And now ANOTHER western internet constellation to add to the list that will likely be launching in the 2025-2027 range (Starlink, Kuiper, Rivada, Telesat, and now OneWeb)
