China Submits Massive Satellite Constellation Plan – What’s Happening.

China has filed applications with usthe United Nations’ International Telecommunication Union (ITU) to reserve orbital slots and radio frequencies for a constellation totalling over 200,000 satellites, dwarfing any existing or proposed low-Earth-orbit (LEO) networks. These filings were lodged in December 2025 by multiple Chinese entities, notably the newly formed Institute of Radio Spectrum Utilization and Technological Innovation — which alone applied for almost 193,000 satellites across two mega-constellations — and other companies including China Satellite Network Group, China Mobile and Shanghai Yuanxin Satellite Technology.

• The two largest proposals — CTC-1 and CTC-2 — each request roughly 96,714 satellites.
• Additional filings from Chinese telecom and space firms add thousands more satellites to the overall total.

If realised, this would be the largest satellite network ever proposed — by a wide margin.

Why China Is Doing This

Chinese space and industry experts say the filings reflect China’s desire to secure scarce orbital slots and spectrum before competitors, and to build a national infrastructure that supports future communications networks (including 6G and integrated space-air-ground systems). Officials have called for greater transparency and coordination in space to avoid congestion.

Under ITU rules, applicants must begin deployment — including launching at least one satellite — within a set timeframe, or they risk losing reserved bandwidth and orbital rights.

Contrast: SpaceX / Starlink Status

At the same time, SpaceX received approval from the U.S. Federal Communications Commission (FCC) to deploy an additional 7,500 second-generation Starlink satellites. This brings the total authorized Starlink constellation to about 15,000 Gen2 satellites, enabling higher-speed broadband and expanded global coverage.

However:

• Starlink initially sought approval for up to 30,000 satellites, but the FCC only authorised half that number.
• Starlink currently operates roughly 9,400 satellites and plans further expansion, which still falls far short of China’s paper filings.

The FCC has set deployment deadlines for SpaceX — including launching 50% of the Gen2 satellites by late 2028 and full deployment by 2031.

Global Reactions & Industry Views

United States & Industry Leaders

• SpaceX executives and U.S. space stakeholders have raised concerns about coordination and safety in orbit, citing incidents where satellites from different countries came dangerously close due to limited data-sharing among operators.
• U.S. regulators have continued supporting Starlink’s expansion, citing broader connectivity benefits and strategic leadership in space broadband.

Chinese Government & Media

• Chinese state media and official commentators describe the filings as evidence of responsibility and ambition, noting the need to secure China’s space infrastructure and spectrum rights against the backdrop of increasing congestion and demand.

International Astronomers & Space Experts

• Independent space and scientific voices warn that proliferation of satellites at this scale could increase collision risks, conflict over orbital slots, and long-term management challenges in LEO. Observatories and researchers have raised similar concerns about satellite megaconstellations’ impact on astronomy and space debris. (See academic and sector reports on sustainability and orbital environment.)

Other Global Players

• Other regions like Europe (IRIS²) and companies like OneWeb and Amazon’s Kuiper are also expanding their satellite ambitions — meaning the orbital broadband competition is truly global and not limited to China vs. U.S. alone.

Technical & Practical Challenges Ahead

Experts point out that even if China secures approvals, deploying 200,000 satellites within mandated timeframes is an immense challenge, requiring potentially hundreds of launches per year — far above historical rocket cadence.

Additionally, satellite megaconstellations face:

• Orbital congestion and collision risk
• Space debris management issues
• High manufacturing and launch costs
• Needs for ground infrastructure and regulatory support

NASA and space agencies worldwide are increasingly focused on space traffic management to avoid accidents and maintain sustainable space operations. (General context from industry reports.)
