China Launches Second Satellite Internet Test Satellite of 2026

China successfully launched a satellite internet technology test satellite early Sunday morning, marking the second such launch in just over a month as the country accelerates its push to develop space-based broadband infrastructure. The satellite lifted off at 02:07 CST on May 31 (18:07 UTC on May 30) from the Xichang Satellite Launch Center in Sichuan Province aboard a Long March 2D (CZ-2D) carrier rocket, according to Xinhua News.

The Launch

The satellite successfully entered its designated orbit, and the mission was declared a complete success. This was the 646th flight of the Long March rocket series, a milestone that underscores China’s rapidly accelerating launch tempo. The first satellite internet test satellite of 2026 was launched on April 24, which was China Space Day, from the same launch site using the same rocket type. That earlier mission was the 639th Long March flight and featured the first use of a 4.2-meter diameter composite fairing on the CZ-2D at Xichang.

CCTV News reported that the satellite is primarily designed to carry out technical tests and verification of mobile phone broadband direct satellite connectivity and space-terrestrial network integration.

Technical Details

The Long March 2D rocket used for this mission is a room-temperature liquid two-stage vehicle developed by the Eighth Academy of the China Aerospace Science and Technology Corporation (CASC). According to the China News Service, the rocket has a 700-kilometer sun-synchronous orbit capacity of 1.3 tons and is capable of both single-satellite and multi-satellite launches for different orbital requirements. It is known for its reliability and versatility in China’s launch vehicle fleet.

Tencent News reported that this mission featured a point-type stacking separation mechanism and a 4.2-meter diameter fairing, technical innovations that enhance the rocket’s payload deployment capabilities. These features allow for more efficient packing and deployment of satellites, which will be critical for the high-volume launches planned for China’s future megaconstellations.

Strategic Context

China is pursuing a dual-track approach to satellite internet, with two major constellations under development. The GW Constellation (“Guowang” or “National Network”), led by China Satellite Network Group Co., Ltd., a state-owned enterprise established in 2021, plans to deploy approximately 12,992 low-earth orbit satellites in two sub-constellations. The Qianfan Constellation (“Thousand Sails”), led by Shanghai Yuanxin Satellite Technology, uses an “one rocket, 18 satellites” deployment model and had launched six batches of satellites as of January 2026. Qianfan won the 2025 World Internet Conference Leading Technology Award for its satellite scale development achievements.

The accelerated testing pace — two launches within 37 days, separated by just seven Long March flights — signals that China is preparing for consumer-grade satellite internet services. The focus on “mobile phone direct broadband satellite connectivity” suggests China aims to compete directly with services like SpaceX’s Starlink direct-to-cell capability, which is already being tested in several markets.

Policy Support and Commercial Progress

The 2026 Government Work Report for the first time separately mentioned “accelerating the development of satellite internet” and positioned aerospace as an “emerging pillar industry.” This high-level policy backing reflects the strategic importance Beijing places on securing low-earth orbit spectrum and orbital slots in an increasingly competitive global environment.

As of May 2026, China’s satellite internet has entered public beta testing. Huawei Mate X6 and other flagship phones support direct satellite connectivity for emergency messaging and low-speed data, with downlink speeds of 5-10 Mbps. Over 30 phone models from Huawei, Honor, Xiaomi, OPPO, and vivo now support direct satellite connectivity, indicating rapid commercialization of the technology.

Analysis and Implications

The two launches within just over a month represent more than routine progress — they signal an intentional acceleration of China’s satellite internet timeline. With the United States (Starlink), the United Kingdom (OneWeb), and other nations pursuing similar capabilities, the race for orbital resources is intensifying. Low-earth orbit is a finite resource, and early deployment confers significant advantages in spectrum allocation and orbital slot claims.

One notable question that remains unanswered is which specific constellation these test satellites will ultimately serve. The official sources do not specify whether they are for the GW constellation, Qianfan, or a separate technology validation program. This ambiguity suggests China may be testing technologies applicable across multiple programs.

What’s Next

China’s satellite internet ambitions are ambitious and clearly defined. By the end of 2026, Qianfan aims for approximately 648 satellites to achieve Asia-Pacific regional coverage. By 2027-2028, the GW constellation plans to deploy roughly 1,300 satellites, while Qianfan targets 1,296 satellites for initial global continuous coverage. The long-term vision includes complete global deployment of over 15,000 satellites by 2030, with satellite communication users exceeding 10 million and 6G commercialization featuring integrated space-terrestrial networks.

These test satellites are critical stepping stones toward that vision, validating the core technologies — direct phone-to-satellite broadband and seamless network integration — that will underpin China’s next-generation communications infrastructure. With each successful launch, China moves closer to a future where satellite internet is as ubiquitous as mobile cellular networks are today.
