China has achieved an important milestone in laser communication technology between satellite and ground. 100 gigabits/second reached the data transmission speed. While this speed was ten times the previous record, it belonged to Elon Musk’s SpaceX company. Starlink He also manages to leave his project behind.

Behind this success is Chang Guang Satellite Technology and its Jilin-1 It has a satellite constellation. Jilin-1, “the world’s largest sub-meter commercial remote sensing satellite network” It is defined as . According to reports, data was transmitted between the mobile-based ground station and one of the 117 constellation satellites orbiting the Earth.

With this success, Wang Hanghang from Chang Guang Satellite Technology They are one step ahead of Starlink stated money, “Musk’s Starlink has inter-satellite laser communications, but has not yet deployed satellite-to-ground laser communications. We think they may have the technology, but we have already begun large-scale deployment,” says

Hanghang added: “By deploying these laser communication units to all satellites in the Jilin-1 constellation, we aim to increase their efficiency and We aim to connect 300 satellites to the network by 2027.”

Behind the success of laser communication technology is a backpack-sized compact laser communication terminal that Chang Guang started developing in 2020. This terminal can transmit data both satellite-to-satellite and from space to Earth.

10 movies can be transmitted in 1 second

Integrated into the satellite Jilin-1 02A02 in June 2023, this terminal communicated with a portable ground station mounted on a mobile truck. This mobile station can overcome bad weather conditions and make data transmission more reliable. It is planned to improve the acquisition efficiency of remote sensing images by establishing multiple receiving stations throughout China.

This great achievement was achieved by overcoming challenges such as atmospheric disturbances, rapid movement of satellites and precise alignment of laser beams. Previously, in October 2023, the same system transferred data from space to Earth at a speed of 10 Gbps. With a transmission speed of 100 Gbps, it will be possible to transmit ten feature films in 1 second. Thanks to satellite-to-ground laser communication, the way has been paved for advanced satellite infrastructures including navigation, 6G internet and remote sensing.
