Beijing, Sep 18 (Alliance News) — China has officially deployed its first operational satellite-to-ground laser communication station on the Pamir Plateau, situated at approximately 4,800 meters above sea level.
This station marks the completion of China’s initial phase in establishing a satellite-to-ground laser communication system.
The new system signifies a transformative shift from traditional microwave ground stations used for satellite data acquisition.
It promises to enhance applications in remote sensing, satellite Internet, and various space missions by providing a high-speed data transfer capability.
Laser communication offers substantial advantages over conventional microwave methods, including access to abundant spectrum resources with bandwidths reaching several terahertz—up to a thousand times greater than that of microwave communications.
The system is also noted for its lightweight, compact design, low power consumption, and high security, supporting large-scale data transmission between satellites and Earth.
The operational success of this station sets a robust foundation for China’s plans to develop a next-generation satellite-to-ground data transmission system and build an advanced satellite ground station network.
