Starlink and the Seven Dwarfs

In the 1960s, IBM dominated the computer market, which was often referred to as “IBM and the seven dwarfs.” IBM is prosperous today, but no longer dominant. The low-Earth orbit (LEO) satellite Internet service market today is reminiscent of that time, but it’s "SpaceX Starlink and the seven dwarfs."

As was the case with IBM, Starlink has seven dwarfs, which I have described in two fairly recent posts. Three are Chinese: Guowang, Qianfan, and Honghu-3, and four are from the west -- the US, Canada, and Europe -- Amazon LEO, OneWeb, Telesat, and IRIS². (Russia may emerge as the eighth dwarf).

Today, Apple's market cap is approximately $3.95 trillion, and IBM's is approximately $278 billion. I do not expect Starlink to drop off that precipitously, but its lead will be significantly diminished. Five of IBM's dwarfs failed, and two merged to form Unisys. I expect Starlink and all the dwarfs will survive, and the gap between them to shrink, but not as dramatically as the gap between IBM and its dwarfs. Here are some of the factors that will shape the future LEO Internet market (in no particular order):
A divided world market
After World War II, the relatively unscathed U.S. became the world’s leading power, shaping a liberal international order through its economic and military strength and promotion of democracy and free markets. Subsequent US actions like the wars in Vietnam and Iraq diminished our global stature, and Trump has accelerated that trend with isolationist policies, while China has been opening. 
This leaves us in a world where some nations will deal only with Starlink and the "western" dwarfs, others will deal only with the Chinese dwarfs, and others will be open to either. This shields the dwarfs and Starlink from total global competition.
Approximate GDP shares (source)
We can get a very rough idea of market opportunities by considering the GDPs of three groups: nations that are members of the G7 and/or the European Economic Area, those that are BRICS-plus nations and/or have Digital Silk Road projects, and the rest of the world. As we see here, the potential market for Chinese dwarfs is somewhat larger using GDP, and the difference would be even greater were we to consider global population percentages.
China is open to private investment

The stereotype of China as a Communist nation with an inefficient, corrupt government controlling everything is outdated. 
Deng Xiaoping’s reforms transformed China from a centrally planned economy into a socialist market economy. During 1978–1992, GDP quadrupled, and productivity, trade, and foreign direct investment surged. Living standards rose sharply, though inequality and regional gaps widened. China transitioned from isolation to global integration, laying the groundwork for its rapid growth in the following decades.
The trends set by Deng continued, and in 2014, China’s State Council opened its space sector to private investment. In 2015, the launch company Landspace Technology, which owns 48% of the developer of the Honghu-3 constellation and is planning an IPO, was founded. As shown here, Landspace provides an example of the mixed ownership structure possible in China today, and many Chinese space companies already have publicly traded stocks. Two other Chinese launch firms are moving toward IPOs, and more are in the works. Many people and organizations, including national and local governments, have stakes in the game.
Government investment and planning
US and China capital formation (source)
It's not government versus private investment; it's the mix of the two. The United States government's planning and investment played a key role in advances in electronic data communication, from Morse's telegraph to Whirlwind, the SAGE early-warning system, the ARPAnet, CSnet, NSFnet, and the NSF Higher-Education and International Connection programs. However, government Internet ownership was phased out in the first half of the 1990s.
After 1978, Chinese policy favored foreign and domestic investment over consumption —for example, investing in infrastructure and (over) investing in housing —while enacting measures like the one-child policy. The Chinese government also plays an active role in planning and setting goals. The 14th Five-Year Plan (2021-2025) called for building an integrated communications, Earth observation, and satellite navigation system with global coverage. 

China’s 15th Five-Year Plan (2026–2030) is expected to promote low-Earth-orbit (LEO) satellite Internet as part of its “new-type infrastructure” strategy. A Ministry of Industry and Information Technology directive calls for  “accelerated development of low-orbit satellite Internet,” commercial trials, and global broadband coverage, targeting over 10 million users, including direct-to-mobile handset service, by 2030. The Communist Party recommendations include building “information-communication networks” and “aerospace and low-altitude economies” as strategic sectors. Together, these indicate that LEO satellite internet will be clearly encouraged within China’s 2026–2030 policy framework.

Note that the Landspace pie chart above refers to "State and Local Government Funds." Local governments play an important role in coordinating and financing space and other industries in China, and Landspace has several key facilities within the G60 Science and Technology Innovation Corridor. (This is reminiscent of Silicon Valley.)

Elon Musk and Donald Trump

Starlink will remain a major satellite ISP, but Elon Musk has tarnished the Starlink and Tesla brands, opening market space for the dwarfs. Many individuals and organizations view Musk's "chainsaw" cuts of federal regulators, watchdogs, experts, and agencies as detrimental and/or cruel. The most striking example of his political acts was dismantling USAID.  A recent study published in The Lancet by researchers from Africa, South America, Europe, and the United States estimates that 91 million deaths were prevented by USAID between 2001 and 2021 and predicts more than 14 million additional deaths globally by 2030, including more than 4.5 million dead children under five. For a real-time update on deaths caused by our aid discontinuation, click here, and for a short documentary, click here.
Musk is reminiscent of Henry Ford. Both were manufacturing geniuses with strong political views that alienated many people. Ford was an antisemitic publisher of the Dearborn Independent, who was praised by Hitler and given the Grand Cross of the German Eagle, the Nazi regime’s highest honor for foreigners in 1938. Hitler also had a portrait of Ford in his office.
The Trump presidency has diminished the United States' stature and soft power/influence in the world. In the first year of his second term, Trump withdrew from the World Health Organization, the Paris Climate Agreement, OECD Global Tax Deal, UNESCO, and the United Nations Human Rights Council. His arbitrary, possibly illegal, tariffs have alienated allies, provoked retaliatory trade measures, and signaled to many nations that the U.S. is an unreliable ally and economic partner. Trump's (and to a lesser extent, Musk's) waffling on Ukraine, where Starlink and, to a small extent, OneWeb have been valuable assets, calls U.S. reliability as an ally into question, opening markets for the Chinese and European dwarfs. 
Starlink has proven to be a valuable military asset in Ukraine, but at one point, there was speculation that Musk would stop the service. He denied that and indeed has not terminated the service, but no government, military, or other organization is comfortable with a sole supplier of a critical good or service, so Canada and European governments will not allow their dwarfs to fail, nor will the United States government, which has multi-billion dollar contracts for Starlink, Starshield, and NASA and DOD launch service. Amazon will compete for U.S. government contracts, and it is conceivable that in a post-Trump world, other western dwarfs might also. (Trump will favor Bezos now that he and Musk have had a falling out).
In the far-far future, one can even imagine global collaboration with China. In May 1961, President Kennedy initiated the "space race" in a joint presentation to Congress requesting funds to put a man on the moon and return him safely by the end of the decade, but by September 1963, he had changed to a call for collaboration in space with the Soviet Union in an address before the UN General Assembly:     
Why, therefore, should man's first flight to the moon be a matter of national competition? Why should the United States and the Soviet Union, in preparing for such expeditions, become involved in immense duplications of research, construction, and expenditure? Surely we should explore whether the scientists and astronauts of our two countries--indeed of all the world--cannot work together in the conquest of space, sending someday in this decade to the moon not the representatives of a single nation, but the representatives of all of our countries.
New technology, distribution channels, and regulations
IBM was dethroned by new technologies like time-sharing, networks, and personal computers. They knew about these technologies and tried new products, but those products failed. For example, Christopher Strachey's early paper on time-sharing was widely read, and IBM had early online projects like the SABRE airline reservation system, the SAGE early warning system, and later general-purpose time-sharing systems(While working for IBM, I first encountered time-sharing on a QUICKTRAN terminal at IBM Research and later built my dissertation on the IBM AN/FSQ-32, a bespoke IBM time-sharing system.) They offered computer networking products like System Networking Architecture and Token Ring, but they failed because of open networking standards like TCP/IP and Ethernet.
IBM was also aware of personal computers from the time of the LINC at Lincoln Labs, and sold personal computers from the early IBM 610 Autopoint in 1957 through the desktop IBM 5100 in 1975, and finally the mass-market IBM PC in 1981. 
The problem was not ignorance or engineering, but the company culture, overhead, and customer base. IBM salespeople were well-paid men wearing blue suits and wingtip shoes, spending months on a sale of a large, expensive computer. IBM was not ready for computer stores and Walmart. SpaceX does not face as extreme a culture mismatch as IBM did, but workers may be unwilling to work the long hours SpaceX is known for.
As the global space industry grows, new technologies and applications will be developed worldwide, and SpaceX and Starlink may be slow or struggle to adopt them, given their commitment to vertical integration, unlike, for example, OneWeb, which has worked with partners from the start. Furthermore, the battle between Trump and universities is hurting research in need of federal funding, while China is funding research and education.
We will also see increasing pressure for global regulation as incidents like the recent stranding of Chinese taikonauts due to a debris strike occur, the world becomes increasingly dependent on space, and LEO becomes increasingly crowded.  Those regulations will constrain Starlink since it already has over 8,000 satellites in orbit and over 8 million customers in over 150 countries. In the US, Jeff Bezos may have more influence over regulatory decisions than Musk, who has fallen out of favor with Trump. (Regulators face a dilemma in trying to achieve national autonomy and space sustainability.
Starship and launch capability
SpaceX's reusable Falcon 9 rocket gives Starlink a significant advantage, but others will master reusability. Blue Origin has recently landed a New Glen booster with significantly greater capacity than the Falcon 9 on a drone ship, China's LandSpace hopes to safely land a Zhuque-3 this year, and many other companies are working on Falcon 9-class reusable rockets.
While these companies will match SpaceX's current launch capability in a few years, catching up will take much longer if its next rocket, Starship, meets Elon Musk's projected cost, payload capacity, and launch cadence goals, but they have had several test launch failures and are behind schedule. Musk has done some amazing things, like achieving routine rocket reusability, but he has also failed to meet ambitious goals. For example, in 2016, he predicted Tesla would complete a coast-to-coast autonomous drive with no human intervention by the end of 2017.
Those are some reasons I expect Starlink's competitors, the dwarfs, to survive and cut into its immense lead. I'd welcome arguments pro and con on my belief that the gap between Starlink and the dwarfs will shrink significantly, but Starlink will continue to be an important player.

Western LEO Satellite Internet Update: OneWeb, Telesat, Amazon Project Kuiper and IRIS²

In an earlier post, I updated the status of three Chinese low-Earth orbit (LEO) satellite Internet constellations. This one looks at four western competitors: OneWeb, Telesat, Amazon Project Kuiper, and IRIS². While Starlink is far ahead of each of them and only OneWeb is in operation at this time, I expect each of these and the Chinese constellations to survive and eventually compete with Starlink (stay tuned for the next post).

OneWeb

Bill Gates and two partners founded Teledesic, a would-be LEO satellite Internet service provider, in 1990, but the technology was not yet ready, and Teledesic declared bankruptcy in 2002.

The next potential LEO Internet service provider, OneWeb, was founded by Greg Wyler, who had extensive experience with networking in developing nations, with the mission of “bridging the digital divide by 2027.” However, it entered bankruptcy in 2020. The company was reorganized and emerged from bankruptcy, and in 2023, it merged with the established geo-stationary satellite (GEO) operator Eutelsat, creating the "Eutelsat Group" company, with subsidiaries "Eutelsat" and "Eutelsat OneWeb.”

In spite of that rocky start, OneWeb is the only company other than Starlink that is offering LEO satellite Internet service today. OneWeb LEO revenue was 187 million euros ($216 million) for the 12 months ending June 30,2025, representing around 15% of total Eutelsat Group sales. Starlink revenue for 2024 was $2.7 billion. OneWeb’s market share, and more importantly, global capacity, are minuscule compared to those of Starlink.

That sounds grim, but given Elon Musk’s political activity, Trump’s MAGA/isolationist policy, and the military value of LEO Internet, Europe will not let OneWeb fail unless there are viable alternatives to Starlink. This is evidenced by European support of OneWeb in Ukraine, including German funding of OneWeb and a recent British investment.

Finally, note that the Eutelsat Group can offer multi-orbit service, switching seamlessly between Eutelsat GEO and OneWeb LEO satellites or offering OneWeb service to other GEO providers. They signed their first multi-orbit contract three years ago and have added others since.

While this gives them an in-house advantage, SES, which operates a middle-Earth orbit constellation, will partner with any LEO or GEO provider to provide multi-orbit service.

Telesat

Telesat, an established Canadian GEO satellite operator, was the next LEO Internet company. Telesat recognized the trend to LEO, but decided not to offer consumer connectivity

Telesat has been beset by delays and has reduced its initially planned constellation size, but they have contracted (with SpaceX) to begin launching satellites next year. Trump’s immigration and tariff policies, along with talk of annexing Canada, assure us that the Canadian government, which, along with Quebec, has invested in Telesat, will not allow it to fail.

Its initial “Lightspeed” constellation will consist of 198 satellites with a mass of 750 kg, roughly that of Starlink V2 mini satellites.  SpaceX is slated to deploy them over the course of a year, starting in mid-2026. Telesat has been booking customers, and their LEO backlog now exceeds their GEO backlog. They plan to provide global service with polar and inclined sub-constellations, are seeking a ground station partner, and have terrestrial deals with VocusOrange, and Space Norway.

While Telesat will not bundle its own LEO and GEO services, they have tested a hybrid deployment between LEO and GEO using the Telesat Lightspeed emulator, showing seamless integration without any issues. Software like the emulator is part of their strategic decision to use Aalyria Spacetime, a multi-layer, multi-orbit operating system for a temporospatial network, which they acquired from Google when the Loon project was abandoned.

Amazon Project Kuiper

Project Kuiper, which has launched 153 satellites, is far behind Starlink, which has over 8,000, but Amazon has many things going for it. From the time it was founded, Amazon was an infrastructure company, and Project Kuiper is an orbiting infrastructure that will be strategically paired with Amazon’s complementary terrestrial infrastructure, like fiber and datacenters. Amazon has vast experience in manufacturing and logistics that will stand them in good stead with the manufacturing of terminals as well as satellites. 

Project Kuiper is a wholly-owned subsidiary and an initiative of Amazon, and Jeff Bezos is the founder of both Amazon and the Blue Origin launch company, which will launch some Project Kuiper satellites. Amazon itself will also be a significant Kuiper user, and Kuiper will use Amazon’s ground station service

That’s the good news, but Amazon faces an FCC deadline to launch half the constellation by July 30, 2026, and the remainder by July 30, 2029. They say they will be able to receive, test, and pack 100+ Kuiper satellites per month into the appropriate fairing and claim to have secured 80 launches, but how fast can they manufacture them? They will apply for a waiver from the FCC if necessary, and, like Elon Musk, Jeff Bezos has a lot of money and attended Trump’s inauguration. Earlier, Musk might have stopped an Amazon waiver, but now Trump is looking into deporting him, and  Bezos has made editorial changes at the Washington Post, which he owns. A political contribution might solve the FCC deadline.

IRIS²

IRIS² (Infrastructure for Resilience, Interconnectivity and Security by Satellite) is a €10.6bn project with 61 percent funded publicly and the balance coming from the SpaceRise industrial consortium, led by Eutelsat, Hispasat, and SES. SpaceRISE will design, deliver, and operate IRIS² for a period of 12 years.

They have contracted for 274 satellites in LEO and 18 in MEO, with first launches anticipated for 2029 and completion in 2030. Eutelsat will act as prime contractor leading the design of the LEO segment and co-leading the development of common system elements. SES will be responsible for procurement, integration, and operation of the MEO satellites, and Hispasat will lead the very-low orbital layer of the constellation and design, deliver, and operate the ground segment, manage operations, and interconnection with terrestrial networks. They also expect to eventually add a GEO sub-constellation.

This is a unique and complex organization that will have to manage suppliers like Airbus, Thales, OHB, Deutsche Telekom, and  Orange. Bureaucracy might be a problem, but Europe can not rely on Starlink as Ukraine has during the war with Russia.

SES's unique three-orbit satellite Internet strategy

SES's three-orbit offering is unique.
In 2021, OneWeb CEO Neil Masterson said, "Interoperability with GEO satellites must happen -- it's common sense ... Customers don't care whether it's a LEO satellite or a GEO satellite -- all they want is connectivity," and ten months later, OneWeb and Intelsat signed the first multi-orbit broadband agreementSES, which was already a LEO-MEO operator in 2021, is now pursuing a three-orbit strategy, but they are not planning to launch a LEO constellation, but will blend multiple partners’ constellations into a unified three-orbit offering.

  • SES's first multi-orbit partnership was Cruise mPOWERED + Starlink,  providing a managed blend of SES MEO and Starlink LEO service for maritime operators, and we can expect similar bundled services in aviation and enterprise markets. 
  • SES and Lynk Global plan to provide direct-to-device (D2D) connectivity through Lynk's "cell towers in space" and SES's MEO backhaul and terrestrial infrastructure. (SES operates the largest fiber network among satellite providers, with global reach through 150 owned and partner teleports and 50 points of presence.) Might SES also offer AST SpaceMobile D2D service?
  • SES recently completed its acquisition of GEO operator Intelsat, giving it 120 LEO and MEO satellites, but it also inherited Intelsat's commitment to buy $250 million worth of LEO capacity from OneWeb over six years, giving it access to an operating LEO constellation.
  • SES and OndWeb's parent company Eutelsat are both members of the SpaceRISE consortium that is building the Iris^2 multi-orbit network.
  • Amazon’s Project Kuiper is ramping up launch campaigns and seeking distribution partners, and SES’s global ground infrastructure and government contracts make selective Kuiper integration plausible, especially for defense and enterprise deals. Project Kuiper expects to offer service in the US and four other countries by the end of March and approximately 26 countries by the end ot next year.
  • Telesat's  LEO constellation Lightspeed targets enterprise and government -- markets SES knows well. If Lightspeed reaches orbit at scale, SES could combine its MEO and GEO coverage with Telesat’s polar-friendly LEO. Telesat also offers GEO connectivity, but instead of offering multi-orbit service, they will sell Lightspeed to other GEO providers. For example, they have an agreement to provide LEO service to Viasat.
These early and potential LEO partners are all US or European companies, and SES is in Luxembourg, which is now a member of NATO, but it was neutral before World War II and is relatively liberal. While it is inconceivable today, might SES collaborate with a Chinese LEO constellation one day? Perhaps starting with geo-fenced service in China or Belt and Road initiative nations.  
This move makes SES unique. They will offer three-orbit service without the cost and delay of a new LEO constellation, and will be able to select the best LEO provider for a given application. They also plan to gradually grow their MEO constellation, adding a satellite every year.
That being said, they are facing stiff competition from Starlink today, and Amazon's Project Kuiper will be in service soon. They will be competing with their partners in some cases and sharing profits with them in all cases. It also remains to be seen how smoothly they can technically and operationally integrate heterogeneous LEO partners at a competitive cost. Stay tuned.

Chinese LEO satellite Internet update

China has pursued a strategy of competition among government-owned organizations, and it initiated two government-owned constellation projects, Hongyun and Hongyan, in 2018. In April 2020, China’s National Development and Reform Commission included “satellite internet” on its “new infrastructures” list, and China applied to the ITU for a new constellation, called  GW. Hongyun and Hongyan were dropped, and GW, also called China Satnet or Guowang, emerged as China’s global Internet service provider and it was followed by two others, Qianfan and Honghu-3. These are all far behind Starlink, but they will have protected markets and China is developing new launch vehicles and satellite manufacturing capacity.

Gwowang

China’s 14th Five-Year Plan (2021-2025) for National Economic and Social Development and Long-Range Objectives Through the Year 2035 called for building an integrated communications, Earth observation, and satellite navigation system with global coverage. Guowang is the constellation they called for.

Guowang consists of two sub-constellations, designated GW-A59 (6,080 satellites) and GW-2 (6,912 satellites). GW-2 will orbit at 1,145 km, and  GW-A59 will orbit around half that. The ITU filing was in September of 2020, and after a long delay, the first ten GW-2 satellites were launched at the end of 2024, and they now have 81 in orbit. The cadence has picked up recently -- China just launched another batch of Guowang satellites. This was the ninth Guowang launch this year and the sixth in the last 30 days. Even at this cadence, it is unclear that they can manufacture and launch enough satellites to meet the ITU launch deadlines. Perhaps the Chinese have decided that, given launch and manufacturing resources, they would not be able to meet ITU deadlines for all of their constellations, so they are focusing on Guowang, which can be seen as most critical for the government.

Little technical information is available, but considering the capacities of the various rockets used to launch Guowang satellites and the number of satellites in each launch, it seems there are two sizes of satellite: large satellites of around 16,600 kg and smaller satellites of around 889 kg. While these are imprecise estimates, they indicate two classes of satellite with different capabilities and functions. (Note that the relatively high altitude GW-2 sub-constellation has both large and small satellites).

Several Guowang test satellites have also been launched, suggesting strategic government and military applications like Signals intelligence, positioning, navigation, and imaging applications in addition to Internet service.

Qianfan

Shanghai Spacecom Satellite Technology (SSST), a private company backed by the Shanghai municipal government and the Chinese Academy of Sciences, is developing the Qianfan constellation. The planned satellites will orbit at 1,160 km, which is higher than the other announced LEO satellite competitors except Telesat. While this will increase latency, collision risk, satellite lifespan, handoff frequency, and coverage footprint should improve.

Their plan called for 648 satellites providing regional service by the end of 2025 and global service with a second 648 satellites by the end of 2027. By 2030, they planned to have 15,000 satellites in orbit and offer direct-to-mobile service, but it does not look like they will make these goals.

It's been a year since the first Qianfan launch, but five months since the last on? Blae. Is the slowdown due to satellite or launch availability, or are they pausing for some redesign, or bothine Curcio reports that they are “having a very hard time" finding rockets to send full batches of 18 satellit to orbit, but they have also had operational problems. The upper stage of the first launches fragmented, creating over 300 pieces of trackable debris, and ninety satellites are in orbit, but fourteen have not reached their operational altitude. Furthermore, the satellites are interfering with astronomy, and some are tumbling. Regardless of the cause for delays, Qianfan is unlikely to meet its ITU launch deadlines.

Qianfan is a more direct competitor to Starlink than Guowang, which is primarily focused on domestic telecommunications and national security. SSST has been actively marketing wholesale service through foreign telecom companies under the Sailspace brand name. They had MOUs with several nations in six initial target markets, as shown below, and they have subsequently been actively marketing in Asia, Africa, and Latin America

Honghu-3

Landspace Technology Corporation was founded in 2015, following a 2014 central government policy shift that opened the launch and small satellite sectors to private capital. Landscape owns 48% of Hongqing Technology, which is developing the 10,000-satellite Honghu-3 constellation. Honghu-3 satellites will be in six planes, ranging from 340-550 km

Landspace has a pending IPO and is developing the Zhuque-3 rocket, which they plan to launch later this year. The Zhuque-3 will carry about 21,000 kg to LEO in an expendable configuration – less than an expendable Falcon 9, but more than a reusable Falcon 9. This connection to a rocket manufacturer is reminiscent of SpaceX's relationship with Starlink and Project Kuiper's with Blue Origin. (Several other Chinese companies are also working on reusable rockets).

Honghu-3 was announced after Guowang and Qianfan, and relatively little is known of their plans and technology, but Landspace has valuable experience as a private company. As you see in this conversation with ChatGPT, Landscape has a complex mix of private, state, and local government investors dating back to its founding, and it estimates the ownership breakdown as roughly 60% private, national government 15-20%, and provincial/municipal around 20%.

Update 9/14/2025

The Hong Kong Office of the Communications Authority has released a report on a Qianfan test using both the standard and high-performance terminals conducted on a cruise ship in Victoria Harbour, Hong Kong. The ship had an unobstructed view of eight satellites orbiting in a plane over Hong Kong.  They tested Web page loading, HD video playback, WeChat video calls, and large online games.

  • The tester accessed the Baidu hot search page using a mobile browser, and images and text loaded quickly; video playback was also smooth.
  • There was no lag or abnormal playback when streaming 4K high-definition video from the CCTV website.
  • The WeChat video communication quality was comparable to that of terrestrial 4G/5G networks. The video remained stable during the test, with no noticeable lag.
  • The user experience while playing League of Legends was good, and the network delay was kept at 60 to 70 milliseconds.

The report also lists the technical specifications of both the standard and high-performance terminals, and speed tests for both terminals are shown below.

Update 10/23/2025

Quinfan resumed launches with a batch of 18 satellites after a six-month delay, presumably to correct for the problems of an exploding first stage, tumbling satellites, and interference with astronomy. They have now launched 108 satellites, and 14 have failed and are decaying, 94 are working, and 67 are in their operational orbit. 

As mentioned above, Blaine Curcio noted that they were also “having a very hard time" finding rockets to send full batches of 18 satellites to orbit, but Andrew Jones reports that they have expanded launch procurement beyond state provider CASC, awarding $187 million in contracts to Landspace, Space Pioneer, and CAS Space. Still, there is no way they will meet the original goals of 648 satellites providing regional service by the end of 2025 and global service with a second 648 satellites by the end of 2027.

Starlink and the seven dwarfs





This post has been superseded, see: 
https://cis471.blogspot.com/2025/11/starlink-and-seven-dwarfs.html


Source: ChatGPT

In the 1960s, IBM dominated the computer market, which was often referred to as “IBM and the seven dwarfs.” IBM is prosperous today, but no longer dominant. The low-Earth orbit (LEO) satellite Internet service market today is reminiscent of that time, but it’s "SpaceX Starlink and the seven dwarfs." 

As of August 2025, Apple's market cap is approximately $3.363 trillion, while IBM's is around $223.03 billion. I do not expect Starlink to drop off that precipitously, but its lead will be significantly diminished. Five of IBM's dwarfs failed, and two merged to form Unisys, which has a market capitalization of $280.18 million; however, I expect all of Starlink's dwarfs to survive.

Let's look at today's dwarfs. 

OneWeb

Bill Gates and two partners founded Teledesic, a would-be LEO satellite Internet service provider, in 1990, but the technology was not yet ready, and Teledesic declared bankruptcy in 2002.

The next would-be LEO Internet service provider, OneWeb, was founded by Greg Wyler, who had extensive experience with networking in developing nations, with the mission of “bridging the digital divide by 2027”, but it entered bankruptcy in 2020. The company was reorganized and emerged from bankruptcy, and in 2023 merged with established geo-stationary satellite (GEO) operator Eutelsat, creating the "Eutelsat Group" company, with subsidiaries "Eutelsat" and "Eutelsat OneWeb.”

In spite of that rocky start, OneWeb is the only company other than Starlink that is offering LEO satellite Internet service today. OneWeb LEO revenue was 187 million euros ($216 million) for the 12 months ending June 30,2025, representing around 15% of total Eutelsat Group sales. Starlink revenue for 2024 was $2.7 billion. OneWeb’s market share, and more importantly, global capacity, are minuscule compared to those of Starlink.

That sounds grim, but given Elon Musk’s political activity, Trump’s MAGA/isolationist policy, and the military value of LEO Internet, Europe will not let OneWeb fail unless there are viable alternatives to Starlink. This is evidenced by European support of OneWeb in Ukraine, including German funding of OneWeb and a recent British investment.

Finally, note that the Eutelsat Group can offer multi-orbit service, switching seamlessly between Eutelsat GEO and OneWeb LEO satellites or offering OneWeb service to other GEO providers. They signed their first multi-orbit contract three years ago and have added others since.

Telesat

Telesat, an established Canadian GEO satellite operator, was the next LEO Internet company. Telesat recognized the trend to LEO, but decided not to offer consumer connectivity

Telesat has been beset by delays and has reduced its initially planned constellation size, but they have contracted (with SpaceX) to begin launching satellites next year. Trump’s immigration and tariff policies, along with talk of annexing Canada, assure us that the Canadian government, which, along with Quebec, has invested in Telesat, will not allow it to fail.

The initial “Lightspeed” constellation will consist of 198 satellites with a mass of 750 kg, roughly that of Starlink V2 mini satellites.  SpaceX is slated to deploy them over the course of a year, starting in mid-2026. Telesat has been booking customers, and their LEO backlog now exceeds their GEO backlog. They plan to provide global service with polar and inclined sub-constellations, are seeking a ground station partner, and have terrestrial deals with Vocus, Orange, and Space Norway.

While Telesat will not bundle its own LEO and GEO services, they have tested a hybrid deployment between LEO and GEO using the Telesat Lightspeed emulator, showing seamless integration without any issues. Software like the emulator is part of their strategic decision to use Aalyria Spacetime, a multi-layer, multi-orbit operating system for a temporospatial network, which they acquired from Google when the Loon project was abandoned.

Amazon Project Kuiper

Project Kuiper, which has only 101 operational satellites in orbit today, is far behind Starlink, which has over 8,000, but Amazon has many things going for it. From the time it was founded, Amazonwas an infrastructure company, and Project Kuiper is an orbiting infrastructure that willbe strategically paired with Amazon’s complementary terrestrial infrastructure, like fiber and datacenters. Amazon hasvast experience in manufacturing and logistics that will stand them in good stead with the manufacturing of terminals as well as satellites. 

Project Kuiper is a wholly-owned subsidiary and an initiative of Amazon, and Jeff Bezos is the founder of both Amazon and the Blue Origin launch company, which will launch some Project Kuiper satellites. Amazon itself will also be a significant Kuiper user, and Kuiper will use Amazon’s ground station service. 

That’s the good news, but Amazon faces an FCC deadline to launch half the constellation by July 30, 2026, and the remainder by July 30, 2029. They say they will be able to receive, test, and pack 100+ Kuiper satellites per month into the appropriate fairing and claim to have secured 80 launches, but how fast can they manufacture them? They will apply for a waiver from the FCC, if necessary, and. like Elon Musk, Jeff Bezos has a lot of money and attended Trump’s inauguration. Earlier, Musk might have stopped an Amazon waiver, but now Trump is looking into deporting him, and  Bezos has made editorial changes at the Washington Post, which he owns. A political contribution might solve the FCC deadline.

IRIS²

IRIS² (Infrastructure for Resilience, Interconnectivity and Security by Satellite) is a €10.6bn project with 61 per cent funded publicly and the balance coming from the SpaceRise industrial consortium, led by Eutelsat, Hispasat, and SES. SpaceRISE will design, deliver, and operate IRIS² for a period of 12 years.

They have contracted for 274 satellites in LEO and 18 in MEO, with first launches anticipated for 2029 and completion in 2030. Eutelsat will act as prime contractor leading the design of the LEO segment and co-leading the development of common system elements. SES will be responsible for procurement, integration, and operation of the MEO satellites, and Hispasat will lead the very low orbital layer (Low LEO) of the constellation and design, deliver, and operate the ground segment, manage operations, and interconnection with terrestrial networks. They also expect to eventually add a GEO sub-constellation.

This is a unique and complex organization that will have to manage suppliers like Airbus, Thales, OHB, Deutsche Telekom, and  Orange. Bureaucracy might be a problem, but Europe can not rely on Starlink as Ukraine has during the war with Russia.

Three Chinese Dwarfs

China has pursued a strategy of competition among government-owned organizations, and it initiated two government-owned constellation projects, Hongyun and Hongyan, in 2016. In April 2020, China’s National Development and Reform Commission included “satellite internet” on its “new infrastructures” list, and China applied to the ITU for a new constellation, called  GW. Hongyun and Hongyan were dropped, and GW, also called China Satnet or Guowang, emerged as China’s global Internet service provider and it was followed by two others, Qianfan and Honghu. These are all far behind Starlink, but they will have protected markets

Gwowang

China’s 14th Five-Year Plan (2021-2025) for National Economic and Social Development and Long-Range Objectives Through the Year 2035 called for building an integrated communications, Earth observation, and satellite navigation system with global coverage. Guowang is the constellation they called for.

Guowang consists of two sub-constellations, designated GW-A59 (6,080 satellites) and GW-2 (6,912 satellites). GW-2 will orbit at 1,145 km, and  GW-A59 will orbit around half that. The ITU filing was in September of 2020, and after a long delay, the first ten GW-2 satellites were launched at the end of 2024, and they now have 81 in orbit. The cadence has picked up recently -- China has launched another batch of Guowang satellites. This was the ninth Guowang launch this year and the sixth in the last 30 days. Even at this cadence, it is unclear that they can manufacture and launch enough satellites to meet the ITU launch deadlines. Perhaps the Chinese have decided that, given launch and manufacturing resources, they would not be able to meet ITU deadlines for all of their constellations, so they are focusing on Guowang, which can be seen as most critical for the government

Little technical information is available, but considering the capacities of the various rockets used to launch Guowang satellites and the number of satellites in each launch, it seems there are two sizes of satellite: large satellites of around 16,600 kg and smaller satellites of around 889 kg. While these are imprecise estimates, they indicate two classes of satellite with different capabilities and functions. (Note that the relatively high altitude GW-2 sub-constellation has both large and small satellites).

Several Guowang test satellites have also been launched, suggesting strategic government and military applications like Signals intelligence, positioning, navigation, and imaging applications in addition to Internet service.

Qianfan

Shanghai Spacecom Satellite Technology (SSST), a private company backed by the Shanghai municipal government and the Chinese Academy of Sciences, is developing the Qianfan constellation. The planned satellites will orbit at 1,160 km, which is higher than the other announced LEO satellite competitors except Telesat. While this will increase latency, collision risk, satellite lifespan, handoff frequency, and coverage footprint should improve.

Their plan called for 648 satellites providing regional service by the end of 2025 and global service with a second 648 satellites by the end of 2027. By 2030, they planned to have 15,000 satellites in orbit and offer direct-to-mobile service, but it does not look like they will make these goals.

It's been a year since the first Qianfan launch, but five months since the last one. Is the slowdown due to satellite or launch availability, or are they pausing for some redesign, or both? Blaine Curcio reports that they are “having a very hard time finding rockets to send full batches of 18 satellites to orbit, but they have also had operational problems. The upper stage of the first launch fragmented, creating over 300 pieces of trackable debris, and ninety satellites are in orbit, but fourteen have not reached their operational altitude. Furthermore, the satellites are interfering with astronomy, and some are tumbling. Regardless of the cause for delays, Qianfan is unlikely to meet its ITU launch deadlines.

Qianfan is a more direct competitor to Starlink than Guowang, which is primarily focused on domestic telecommunications and national security. SSST has been actively marketing wholesale service through foreign telecom companies under the Sailspace brand name. They had MOUs with several nations in six initial target markets, as shown below, and they have subsequently been actively marketing in Africa.

Honghu-3

Landspace Technology Corporation was founded in 2015, following a 2014 central government policy shift that opened the launch and small satellite sectors to private capital. Landscape owns 48% of Hongqing Technology, which is developing the 10,000-satellite Honghu-3 constellation. Honghu-3 satellites will be in six planes, ranging from 340-550 km

Landspace has a pending IPO and is developing the Zhuque-3rocket, which they plan to launch later this year. The Zhuque-3 will carry about 21,000 kg to LEO in an expendable configuration – less than an expendable Falcon 9, but more than a reusable Falcon 9. This connection to a rocket manufacturer is reminiscent of SpaceX's relationship with Starlink and Project Kuiper's with Blue Origin.

Honghu-3 was announced after Guowang and Qianfan, and relatively little is known of their plans and technology, but Landspace has experience as a private company. (I asked the ChatGPT, Gemini, and Copilot chatbots how much state and private capital Landspace had received since it was founded, and the answers and explanations varied so much as to make them worthless, but they all agreed that the private investment was greater than the public.)

Estimating Guowang Internet service satellite mass with ChatGPT

After searching for the mass of China's Guowang Internet-service larger satellites and finding nothing, I estimated it using ChatGPT. Since I knew the number of satellites (10) and the rocket used (Long March 5B) in two launches, the mass of a single satellite could be estimated if I knew the carrying capacity of the rocket.

I asked ChatGPT this question five times: How much mass could a Long March 5B rocket with a Yuanzheng-2 (YZ-2) upper stage carry to 1,100 kilometers with an inclination of 86.5 degrees? The average answer was 16.6 tonnes or 16,600 kg.
ChatGPT's five answers and the "reasoning" that led to them can be found here. Each is different --  ChatGPT does not remember prior submissions of the same question. I am not a rocket scientist and can only average the five results in estimating the satellite masses. I'd like to know what experts think of the results and the reasoning leading them.
There have been four launches of smaller satellites, and so far, 889 kg is a rough estimate of their average mass.

OneWeb can’t come close to replacing Starlink in Ukraine, but it could complement it.

Elon Musk assured us that he would not stop the Starlink service in Ukraine. But, given his feud with Trump, his criticism of President Zelensky, and his rash actions with DOGE, can he be trusted? (His termination of USAID is estimated to have resulted in 340,000 deaths so far.)

When asked about Musk’s influence, Josef Aschbacher, director general of the European Space Agency, said he declined to comment on “the internal politics of the United States and who should influence these decisions” but added “If changes happen and if our US partners and friends are changing their plans, of course we will be ready for plan B.”

The US has decided to reduce aid to Ukraine, and Plan B is being considered. Eutelsat is in talks with the EU about the possibility of replacing Starlink in Ukraine

Eutelsat OneWeb is currently the only low-earth orbit (LEO) alternative to Starlink. Germany has paid for “fewer than 1,000” OneWeb terminals in Ukraine, but Eutelsat CEO Eva Berneke says the company aims to increase this to between 5,000 and 10,000 "relatively fast."

That is admirable, but I don’t see how OneWeb could come close to replacing Starlink in Ukraine.

For a start, there are limitations of the OneWeb satellites and terminals:

  •  Oleg Kutkov, a leading Ukrainian Starlink expert, estimates that there are around 130,000 Starlink terminals in Ukraine.
  • SpaceX has over 7,500 LEO satellites compared to OneWeb’s 630. (Eutelsat also has 35 geostationary (GEO) satellites).
  • Kyivstar, the largest mobile operator in Ukraine, plansdirect-to-device Starlink connectivity later this year.
  •  Kyivstar has determined that  OneWeb currently lacks sufficient capacity to move forward on their partnership MOU at this time.
  • OneWeb satellites orbit at around 1,200 km, while Starlink satellites are between 336 and 570 km, which gives them a latency advantage for real-time battlefield applications.
  • OneWeb’s fixed beams enable it to provide guaranteed service levels in specific locations, but Starlink’s dynamic-beam architecture makes better use of available capacity in densely populated areas and in tracking mobile users.
  • OneWeb’s fixed terminals are more expensive than Starlink’s, and the portable terminals are heavier and more expensive.
  • There are ten different Starlink terminal models/revisions – they have had time to iterate designs and mature and refine manufacturing processes for both terminals and satellites.
  • Similarly, Starlink satellite designs have evolved – throughput has increased, intersatellite links were introduced, etc.

More importantly, Starlink is embedded in Ukraine. Systems, supply chains, distribution channels, organizations, and applications have been developed around it, and users, engineers, repair people, etc., have been trained. The first Starlink terminals arrived in Ukraine over three years ago. A week later, they were in the field and providing nationwide connectivity through ground stations in three nearby countries, and within a month, there were 5,000 Starlink terminals in Ukraine. Starlink has played an unprecedented, critical role in the management of the war, international relations, and on the battlefield field and it has enabled significant civilian tech mobilization.

One more factor – Starlink is financially stronger than Eutelsat. Eutelsat stock was €28.06 per share in April 2015. When Trump berated Zelensky at the White House on February 28, 2025, it was down to €1.20. As a result of that meeting, it jumped to €7.84 on March 3, but it’s now back down to €2.31.

While OneWeb cannot replace Starlink in Ukraine, it can complement it. For example, OneWeb could provide connectivity and resilient backup for fixed locations like government offices and hospitals, and since Eutelsat operates both GEO and  LEO satellites, latency-tolerant applications like streaming video could be offloaded onto their GEO satellites.

Remembering Dave Taht

  

“Elon, let me inside this thing, and I can fix it for you” (Image from this podcast)

In my own mind, I like to think of him as the person who added the most effective capacity to the Internet, Karl Auerbach

Dave Taht died on April 1st. I met him only recently, and never in person, but his passing saddens me. His technical work and evangelism have improved the Internet, and I will give some examples of his contributions to the Internet community and users, but I am sad because he was a good person — idealistic, unselfish, open, and funny. I'll miss him. First, his contributions, then his values.

Contributions

Taht was best known for his work on buffer bloat and its impact on Internet performance. As packets hop across the Internet, they are queued in buffers while waiting to be forwarded.  Long queues, “buffer bloat,” means increased latency, transit time between a source and its destination, and jitter, transit time variance.

Internet service providers typically advertise and price based on service speed, but latency is critical to interactive applications like gaming, teleconferencing, and Web surfing. (For a deep dive on buffer bloat, see this post by Jim Gettys, who coined the term buffer bloat.)

With Jim Gettys, Taht co-founded the buffer bloat Project, where he implemented, tested, and integrated active queue management (AQM) algorithms CoDel, FQ-CoDel, and CAKE, and led the CeroWRT (Customer Edge Router Wireless Router) project that focused on home, office, and other edge networks.

Gettys shared Taht's focus on the edge, writing “Surprising to most, AQM is essential for broad band service, home routers, and even operating systems: it isn't just for big Internet routers” in 2011 and more recently he said “Buffer bloat can happen anywhere in a network, though by far the most common locations are before/after the WiFi hop in the router, and then the hop from the home router back to the ISP”

Given his interests in space and edge networks, Starlink was a natural focus for Taht, and he talked about Starlink in this 8-minute podcast excerpt. Taht had known Elon Musk since he had worked on an ill-fated satellite that was on a Falcon 1 rocket when it blew up, so he emailed Musk in 2013 and offered to help, but Musk was not interested. The plan for Starlink was announced in January 2015, and when it eventually entered beta in 2020, Taht learned of the latency problem and emailed Vint Cerf, who arranged a meeting with Starlink engineers on Taht’s boat, but he did no work for them.

In January 2024, Elon Musk announced that “the biggest single goal for Starlink from a technical standpoint is to get the mean latency below 20 ms." By March, they were delivering results and listing latency as well as upload and download speed on their availability map. Unfortunately, Musk and his engineers did not listen to Taht in 2013 and 2020.

Values

The National Science Foundation backbone network (NSFNET) was created in 1986 to serve research and education in the US. The network grew rapidly, and in 1988, access was expanded to include international research and education organizations. By 1996, 28 nations were connected. (Fun fact – Cuba’s first link was to NSFNET.)

Taht was 30 years old when NSFNET was decommissioned and the Internet transitioned to fully commercial operation, but his values were established by then. With his skill and experience, he could have found lucrative work or built a large company, but he was committed to open-source software and universal connectivity.

Everything he wrote was open-source, including his songs. He is surely the only composer/musician to write geeky songs about the Internet, for example, this little ditty about the GNU Public License, Richard Stallman, Linus Torvalds, and Eric Raymond. He also spent years in Nicaragua, trying to find ways to bring the Internet (and power, lighting, food, medicine, and books) there as an outgrowth of Nicholas Negroponte’s One Laptop Per Child project.

He understood J. C. R. Licklider’s conception of the Internet as a means of creating communities of common interest rather than common location. He created a Starlink list, which is where I met him. The caliber of conversation on the list is an implicit tribute to Taht.

The photo of Taht at the top of this post was taken from the podcast in which he offered to fix the Starlink router, which was in beta at the time, for free (though he wouldn’t mind a thank-you tweet, a new motor for his boat, or even a Christmas card). The photo illustrates his values. He could have lived in a mansion, but he chose to live on a boat with a guitar nearby. To know Dave Taht better, watch the entire video.

Appendix

I met Dave recently and only knew him online, so I asked Perpleity, Gemini, Grok, and ChatGPT to list memorials. They returned several broken links, and Claude and Deepspeak were not current. I found these:
