StarSilk Completes Multiple Strategic Funding Rounds, Deepening Focus on Commercial Aerospace and 5G/6G Satellite Internet

StarSilicon announced today that it has recently completed multiple strategic funding rounds. The first was co-led by Ceyuan Capital and Hengqin Shenhe Investment, with participation from Gaorong Ventures, Chengdu Sci-Tech Innovation Investment, Fujian Industry Investment, Luxin Capital, Xindongneng Capital, CICC Capital, Puxin Capital, Puwin Capital, Hanguang Yiyi, Qingyue Capital, and other state-owned and market-driven funds, plus continued follow-on investment from existing shareholder Langrun Lifang. The second was co-led by Yuanhang Capital and Pianxuan Fund, with participation from Shanghai Industrial Intellectual Property Fund, Dingxing Quantum, and others.

Deep Roots in Commercial Aerospace and 5G/6G Satellite Internet

StarSilicon focuses on 5G/6G communications technology, providing customers with competitive full-scenario space-air-ground integrated chips and solutions, including 5G/6G eMBB, RedCap, and NTN terminal/smartphone baseband chip platforms and solutions. Its industry applications cover smartphone direct-to-satellite, satellite communication terminals, airborne communications, UAV ad-hoc networks, eVTOL integrated sensing and communications, vehicular communications and smart cockpits, 5G FWA fixed wireless access, emergency communications, trunked radio, industrial IoT, and vertical industry applications — spanning 5G/6G ubiquitous connectivity and satellite communication scenarios.

With the national strategic push for technological innovation, commercial aerospace, and 6G satellite internet development, StarSilicon — as a participant in multiple national science and technology megaprojects related to low-earth-orbit satellite internet and 5G NTN smartphone direct-to-satellite baseband SoC chips — has consistently answered the national call and embraced its mission. Over the past several years, it has maintained high investment in commercial aerospace and 5G/6G satellite internet, making it the industry's only vendor with full-series commercial solutions for L-band, S/C-band, and S/S-band 5G NTN smartphone direct-to-satellite baseband SoC chips, as well as Ku-band and Ka-band 5G NTN satellite communication terminal baseband SoC chips. Through concrete action, it implements national strategic planning and contributes technical strength to the high-quality development of China's commercial aerospace satellite internet industry.

Leading the 5G NTN Smartphone Direct-to-Satellite Direction

As 3GPP NTN becoming the mainstream international standard for satellite communications has become industry consensus, China has established global leadership in the 5G NTN field — a demonstration not only of the nation's hard technological power but also a significant achievement of strategic national planning.

As the sole research and development contractor for multiple satellite communication baseband SoC chips, StarSilicon has particularly focused on 5G NTN smartphone direct-to-satellite, the most promising application scenario in commercial aerospace. It has consistently stood at the frontier of technological uncharted territory: from laboratory testing in 2023, to field testing in 2024, to successful in-orbit verification in 2025 that achieved the world's first 3GPP 5G NTN standard-based smartphone direct-to-broadband-satellite high-definition video call. Throughout this journey, StarSilicon has provided robust support for technical validation and breakthroughs at major low-earth-orbit satellite internet constellations, as well as multiple world-first achievements, laying a solid technical foundation for the nation's commercial aerospace satellite internet endeavors.

Accelerating China's Commercial Aerospace Satellite Internet Industry

StarSilicon's founding team comprises senior engineers with over two decades of roots in China's communications industry, who have witnessed and participated in the entire leapfrog development of China's communications sector — from follower to peer competitor to leader: starting from the "seven countries, eight systems" technological void of 1G, following in 2G, breaking standard monopolies in 3G, catching up in 4G, and achieving global leadership in 5G. Having built solid communications technology expertise, the team was drawn by the national strategic call to venture into the entirely new track of commercial aerospace and 6G satellite internet, dedicating their accumulated technical expertise to serving a new national science and technology strategy.

The foundation of commercial aerospace satellite internet is communications. Starting from high-performance communications chip architecture design, StarSilicon has tackled the challenges of high-speed algorithm implementation and optimization, terminal RF device adaptation, and full-system integration and validation, achieving fully autonomous and controllable 5G NTN satellite communication baseband technology and establishing a complete "chip-algorithm-system" vertical layout.

With the support of numerous state-owned strategic investors, and facing the new journey of the 14th Five-Year Plan's two strategic directions — commercial aerospace and 6G — StarSilicon will continue to uphold its original mission of serving national strategy, guided by technological innovation, constantly breaking through technical bottlenecks, contributing to the high-quality development of China's commercial aerospace satellite internet industry, helping the nation gain greater advantage in global low-earth-orbit satellite communications competition, and dedicating more wisdom and strength to accelerating the building of a world leader in science and technology.
