Breakthrough in Satellite-to-Ground Laser Communications
China’s Chang Guang Satellite Technology Co. has set a new record for satellite-to-ground laser data transmission, achieving speeds of 100 Gbps. This milestone, reported on January 2, is 10 times faster than their previous record and positions them ahead of SpaceX’s Starlink in this technology.
Applications for 6G and Advanced Satellite Technology
The innovation supports next-generation technologies such as 6G networks, ultra-high-resolution remote sensing, and advanced satellite navigation. The company plans to upgrade its Jilin-1 satellite constellation with laser communication to connect 300 satellites by 2027.
Laser Technology Outpaces Microwave Transmission
Laser communication addresses the bandwidth limitations of traditional microwave data transmission. This development aligns with 6G objectives to deliver wide coverage and low-cost communications.
Global Context and Competitive Edge
While MIT and NASA have achieved higher laser transmission speeds, Chang Guang’s system stands out for its practical application. Their mobile truck-mounted ground station enhances data reliability and adaptability, enabling real-world deployments.
Future Plans and Expansion
The company aims to expand its data reception network across China to improve remote sensing efficiency. With this breakthrough, Chang Guang solidifies its leadership in satellite data transmission technology.
