How China cut the cost of its Qianfan satellites by over 96%

China's ambitious low-Earth orbit (LEO) internet satellite project, the Qianfan Constellation, has achieved a significant milestone, with over 200 satellites now in orbit as of early June 2026. The project is accelerating its deployment through a remarkable cost-reduction strategy and a commitment to sustainable space operations.

The number of Qianfan satellites in orbit has surged to 200 as of June 5, according to Hu Haiying, president of the Innovation Academy for Microsatellites at the Chinese Academy of Sciences and chief commander of the Qianfan constellation satellite system.

Qianfan is no longer just an experiment, it is entering a phase of high-frequency, large-scale deployment as part of China's ongoing efforts to build a LEO satellite internet constellation.

Both China's Qianfan and SpaceX's Starlink operate in LEO, roughly 300 to 2,000 kilometers above Earth. At this altitude, satellites function like "base stations in the sky" – close enough to offer minimal latency and powerful enough to form a "space net" of tens of thousands of nodes. 

This architecture is designed specifically to eliminate connectivity dead zones in remote mountains, deep oceans and polar regions where terrestrial towers cannot reach.

The constellation, operated by Shanghai-based Spacesail Technologies, is leveraging an industrialized production model to slash satellite manufacturing costs. Traditional communication satellites can cost up to 300 million yuan (about $42 million) each. In contrast, the standardized, flat-panel Qianfan satellites are now produced for approximately 10 million yuan per unit – a reduction of over 96%.

This cost efficiency is achieved through mass production, modular design and a "fast iteration" philosophy that accepts a higher failure rate in exchange for speed, relying on network redundancy to maintain service.

"China built the world's best 5G infrastructure. Because our ground network was so good, we didn't feel the immediate need for satellite internet," Hu explains.

High-density launches

Deployment is proceeding at a rapid pace. The project utilizes a "one rocket, many satellites" launch model, with two successful high-density launches occurring within two days in early June from the Taiyuan and Wenchang launch sites.

This schedule aims to complete a 324-satellite initial network by July, providing regional broadband coverage. The long-term goal is to expand the constellation to over 15,000 satellites for global coverage by 2030.

The project's urgency is driven by the need to secure scarce orbital slots and frequency resources under international "first-come, first-served" rules. With competitors like SpaceX's Starlink already operating over 10,000 satellites, China is racing to capture the remaining viable positions.

"The orbit and frequency are non-renewable resources," Hu said. As of June 2026, Starlink has over 12,400 satellites in orbit, occupying more than 60% of active global satellite slots. They have locked up nearly 70% of the prime real estate between 500-600 kilometers – the sweet spot for direct-to-cellphone connectivity.

"If we don't launch and use them, we are simply giving these resources away," Hu says.

In late 2025, China filed applications for 203,000 satellites to the International Telecommunication Union in a bid to secure future capacity.

Build for the future

Addressing growing international concerns about space debris, the Qianfan satellites are designed with a built-in "green" feature. Each satellite has a planned operational lifespan of seven years and is equipped with a de-orbiting system. At the end of its service, the satellite will automatically maneuver to burn up completely upon re-entering Earth's atmosphere, leaving no long-term space junk.

The new design also allows for stacked launches.

"We can now launch 18 satellites at once," Hu describes. "It's like skipping stones on water. The upper stage spins and through centrifugal force, the satellites separate one by one without collision."

Beyond basic internet, Qianfan is viewed as critical for emerging "space-based computing," where data processing could leverage limitless solar power and the cold vacuum of space, potentially offering a greener solution for the AI era's immense energy demands.

Looking beyond connectivity, the constellation is positioned as global public infrastructure. Spacesail envisions satellite broadband becoming as affordable and accessible as utilities, targeting ocean-going vessels, commercial aviation and remote regions, especially those in the developing world.

If realized, the Qianfan network could help narrow the digital divide for communities where massive fiber and cell towers remain impractical.
