Chang Guang Satellite Technology Co is located in No. 1299, Mingxi Road, Beihu Technological Development Zone, Changchun City, Jilin Province, China People’s Republic of China.. in which their philosophy is Unity, Innovation, hard work and pragmatic ..

Their Story is CGSTL (Changguang Satellite Technology Co., Ltd) is the first commercial remote sensing satellite supplier in China. Now, CGSTL has set up a commercial business dealing with the development and operation of commercial satellites as well as remote sensing information processing all in one. hang Guang Satellite Technology Co., Ltd. ( CGSTL), founded on December 1st, 2014, it’s a unique commercial aerospace enterprise with the development and operation of satellite research, management as well as remote sensing information processing all in one. With a total registered capital of 1.97 billion RMB, the company comprises Jilin Provincial Government, Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), social capital, and technical backbone.

For the first time, Commercially China, People’s Republic of China has independently completed the commercial application of satellite-to-ground laser high-speed image transmission test! Changguang Satellite Technology Co., Ltd. (Changguang Satellite) used a self-developed vehicle-mounted laser communication ground station to conduct a satellite-to-ground laser high-speed image transmission test with the “Jilin-1” constellation MF02A04 satellite-borne laser terminal and achieved success. This marks that Changguang Satellite has successfully engineered the entire business chain of satellite-to-ground laser high-speed image transmission, and its engineering application capabilities have reached the international advanced level. This is also the first time that my country has independently completed a commercial application of satellite-to-ground laser high-speed image transmission tests.

[For the first time, Commercially China, People’s Republic of China has has independently completed the high-speed image transmission test of satellite-to-ground laser for commercial applications] Changguang Satellite Technology Co., Ltd. (Changguang Satellite) uses a self-developed vehicle-mounted laser communication ground station to carry out satellite-borne laser communications with the “Jilin-1” constellation MF02A04 The laser terminal has carried out satellite-to-ground laser high-speed image transmission tests and achieved success. This marks that Changguang Satellite has successfully engineered the entire business chain of satellite-to-ground laser high-speed image transmission, and its engineering application capabilities have reached the international advanced level. This is also the first time that my country has independently completed a commercial application of satellite-to-ground laser high-speed image transmission tests.



The “Jilin-1” constellation is the core project under construction of Changguang Satellite. As the spatial and temporal resolution of the constellation continues to improve, the amount of data it generates increases exponentially. At the beginning of 2020, Changguang Satellite realized that the bandwidth of satellite-to-ground data transmission links has become a “stuck neck” problem that restricts the transmission of massive data from satellites. Laser communication has become a massive problem due to its high bandwidth, low latency, and good security. One of the best solutions for ultra-high-speed data transfer. In March 2020, Changguang Satellite simultaneously established a research team for “vehicle-mounted laser communication ground station” and “space-borne laser communication terminal” based on business applications. Based on the design principle of “simple and reliable”, we adopt the joint design concept of heaven and earth to carry out comprehensive research and development work. On April 8, 2023, the vehicle-mounted laser communication ground station and the space-borne laser communication terminal completed the ground horizontal docking test with a horizontal distance of 500m, achieving 10Gbps downlink and 10Mbps uplink two-way laser communication. On June 14, 2023, the vehicle-mounted laser communication ground station and the “Jilin-1” MF02A04 satellite-borne laser terminal carried out a satellite-ground two-way acquisition and tracking test, completing the satellite-ground two-way link establishment for the first time. On October 5, 2023, the vehicle-mounted laser communication ground station received the 120GB remote sensing image downloaded from the MF02A04 satellite-borne laser terminal, completing the first satellite-ground two-way high-speed laser image transmission test.

The laser communication ground station independently developed by Changguang Satellite adopts a vehicle-mounted configuration. It not only has the characteristics of high bandwidth and miniaturization, but can also be moved at any time and deployed anywhere. Through the flexible change of the ground station site, it can avoid extreme weather and atmospheric turbulence. Providing effective support, this feature will bring huge improvements to the reliability and stability of satellite-to-ground laser data transmission. Wang Xingxing, technical director of Changguang Satellite Laser Communication Ground Station, said, “The communication bandwidth of this satellite-to-ground laser image transmission test reached 10Gbps, which is more than 10 times the traditional microwave data transmission bandwidth. In the future, Changguang Satellite plans to expand this bandwidth to 40Gbps ~100Gbps, with stations deployed in many places across the country, will greatly improve the efficiency of Jilin-1 remote sensing image data acquisition.”

Since its establishment, Changguang Satellite has always been committed to using scientific and technological innovation to promote the progress of satellite technology and the development of the aerospace industry. The application of satellite-to-ground laser high-speed image transmission technology will provide more real-time, high-quality remote sensing data in disaster warning, environmental monitoring, resource management and other fields, and provide better technical support and services for high-quality national economic and social development and social public needs. . (Jilin No. 1)
