China achieved a major milestone in its space endeavors with the successful launch of its first communications satellite, Lingxi-03. This satellite, developed by Beijing-based start-up GalaxySpace, boasts cutting-edge technology, including an ultra-thin flexible solar wing and a state-of-the-art digital payload. The launch aims to test key technologies for a massive 13,000-satellite broadband mega constellation in low-Earth orbit, signaling China’s ambition to compete with SpaceX’s Starlink project.
The Lingxi-03 satellite
The Lingxi-03 satellite stands out for its revolutionary bendable solar panel, which measures a mere 1 mm thick, comparable to the thickness of a credit card. This is just 5% of the thickness of traditional solar panels used in space missions. However, what is truly impressive is its expansion capability. Once deployed in orbit, the solar panel unfolds to an astonishing 9 meters in length and 2.5 meters in width, expanding from its folded thickness of 5 cm. This innovative design allows for significant space-saving during launch and ensures greater efficiency in capturing solar energy.
Lightweight, Efficient, and Scalable
The flexible solar wings used in the Lingxi-03 satellite are not only ultra-thin but also small, lightweight, and highly efficient at absorbing solar energy. These attributes make them ideal for large-scale stackable satellite launches, enabling cost-effective deployment of the proposed 13,000-satellite broadband constellation. GalaxySpace’s chief technology officer emphasizes the importance of this design, as it opens up possibilities for rapidly scaling up the satellite network while keeping costs manageable.
High-Speed Data Handling Capabilities
One of the key highlights of Lingxi-03 is its digital payload, equipped to handle high volumes of data, reaching tens of gigabytes per second. This impressive data handling capacity is essential for providing seamless and high-speed broadband services to users on the ground. With this capability, Lingxi-03 will not only cater to individual consumers but also support various data-intensive applications for industries and governments alike.
Advancing Communication Technologies
The objectives of Lingxi-03’s mission are comprehensive and forward-looking. By testing next-generation low-orbit broadband communications, the satellite aims to set new benchmarks for internet connectivity. Additionally, the mission will evaluate active thermal control technologies, crucial for maintaining the satellite’s operational efficiency in the harsh space environment. Furthermore, the successful testing of stackable satellite release technologies will pave the way for more streamlined and cost-effective satellite deployment.
Ground-based Station Capabilities
Lingxi-03 is not just a communication satellite; it also possesses ground-based station capabilities, enabling it to receive, process, and analyze a significant amount of user information. This feature complements the satellite’s role in providing widespread internet coverage, helping optimize network performance and enhance user experiences.
GalaxySpace: Pioneering Satellite-based Internet Services
GalaxySpace, the startup behind Lingxi-03, has shown its commitment to revolutionizing satellite-based internet services. Established in 2018, it is China’s first company dedicated solely to this field. The recent funding of $1.58 billion demonstrates the growing interest and confidence in GalaxySpace’s capabilities and the potential of satellite-based internet services.
