CGST opens a new era in space communication with Earth.
Chinese satellite company Chang Guang Satellite Technology (CGST) has successfully tested data transmission from an orbiting satellite to a mobile ground station using ultra-high-speed laser communication. This step is considered important on the way to commercial application of this technology.
CGST, which operates the world's largest satellite constellation, Jilin-1, transmitted images from one of its 108 Jilin-1 satellites to a vehicle-mounted optical telescope at a rate of 10 gigabytes per second. The mobile station has a high capacity and can be deployed anywhere to avoid cloud cover or extreme weather conditions.
"The data transfer rate in this test reached 10 gigabytes per second, which is 10 times the speed of radio frequency links traditionally used for satellite communications," said Wang Xingxing, CGST's technical director for Laser Communications.
In the future, CGST plans to increase the bandwidth to 40-100 Gbit / s and use such stations in different regions of the country to increase the efficiency of image acquisition.
However, the company did not provide details about the configuration of the ground station, including the characteristics of the telescope or the type of vehicle used.
Earlier in June, CGST conducted a similar test in collaboration with the Aerospace Research Institute of the Chinese Academy of Sciences. This was the first such test for commercial use in China.
CGST plans to expand the Jilin-1 constellation to 300 satellites in low-Earth orbit by 2025.
In the world, many space agencies and the US military are developing laser communication systems. For example, the Terabyte Infrared Delivery system developed by NASA and the Massachusetts Institute of Technology showed a data transfer rate of 200 Gbps earlier this year.
