1. Core Test Achievements
During the in-orbit laser communication test of the inaugural constellation of the "San Ti Computing Constellation," the Helium Starlight team successfully overcame the technical bottleneck of long-term stable link establishment for low-cost laser communication payloads. Under the condition of a 1,000 km inter-satellite distance (the "05-08 link"), the system completed broadband inter-satellite laser communication verification. It achieved a single continuous stable link duration of over 192 hours (8 consecutive days without disconnection), with zero link failures and a communication link availability rate of over 99.99%.
2. Key Technological Breakthroughs
Inter-satellite laser communication is the core technology for building the "backbone" of Low Earth Orbit (LEO) satellite internet, determining whether satellites can directly achieve high-speed interconnection and data computing in space. The core challenge of this test was achieving both "low cost" and "long-term stability." Through full-chain independent R&D, Helium Starlight conquered the long-term stable link algorithm for low-cost payloads. Without manual intervention or calibration, it maintained reliable transmission of high-speed business data throughout the entire process, significantly reducing the link scheduling overhead for large-scale constellation networking.
3. Mass Production Capability and Industrial Layout
The birth of this record is built upon a robust industrial manufacturing foundation. Helium Starlight has built the first domestic mass-production line for space-borne laser communication terminals in Wuxi, Jiangsu Province, with an annual capacity of nearly 400 units. Related products have entered the supply chain of the national satellite internet project. As of July 2026, the number of its independently developed laser communication terminals in orbit has approached 30, ranking first among domestic private aerospace enterprises. Additionally, the company recently signed an agreement to build a high-end laser communication R&D center in Wuhan Optics Valley, further expanding its production capacity and upstream/downstream ecosystem layout.
4. Industry Competition Landscape and Future Outlook
Currently, the domestic commercial aerospace laser communication track has formed a tripartite competitive landscape: research institute factions represented by the Xi'an Institute of Optics and Precision Mechanics/CAS, capital factions represented by Yingtian Optics, and commercial aerospace new forces represented by Helium Starlight. All parties are racing to build mass-production lines, committed to driving down the cost of laser communication terminals and scaling up production capacity. Facing the capacity and cost pressures brought by SpaceX's "Starship" internationally, domestic enterprises are accelerating the transformation of single-point technological advantages into scale advantages to seize the core entry ticket for the future trillion-dollar LEO constellation market.
