(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. .

At 1330 Hours Hong Kong SAR- Beijing Time 15th June 2023 , China- People’s Republic of China- CNSA –China National Space Administration Successfully launched the New Next Generation Long March – Chang Zheng2D carrier rocket at the Taiyuan Satellite Launch Center Shanxi Province.. launch 41- forty one Satellites in which the Chang Zheng – Long March 2D Carrier Rocket is in preparing readiness to launch in which dates back to On May 22, a total of 41 satellites set off in the Changchun Aerospace Information Industry Park, among them, “Jilin No. 1” Gaofen 03D19-26 satellites, Gaofen 06A series satellites, platform 02A01-02 The 36 satellites including Si-1 are the “Jilin-1” satellites.
The Chang Zheng- Long March 2 D yao 88 carrier rocket at the No. 9 station of the Taiyuan Satellite Launch Center, with the method of “one Carrier Rocket 41 satellites “, 41 optical remote sensing satellites of Jilin No. It entered the predetermined sun-synchronous orbit, and the launch mission was a complete success.
In response to the launch mission requirements of “one arrow with 41 satellites”, the Changerding rocket development team took a series of effective measures to ensure the safe and accurate orbiting of 41 satellites by rationally arranging in the limited fairing space and selecting the optimal separation scheme. .
[Chang Zheng – Long March 2D yao 88 /Jilin-1 “One Carrier Rocket 41 Satellites” adopts the satellite layout of wall-mounted*38+sidewall*3】
One arrow launches 41 satellites, setting a new record for the largest number of satellites launched in one time in my country. But to safely and smoothly send so many satellites into orbit at one time, the first thing to solve is the layout of the satellites in the fairing, not only to ensure “sit down”, but also “sit comfortably”. To this end, the development team of Eight Director Erding fully sorted out the structure and mission requirements of the satellites, fully tapped the potential, optimized the layout design, adopted the layout method of 38 satellites on the wall + 3 satellites on the side wall, and successfully found 41 satellites. Safe and comfortable location.
In order to allow 41 ” satellite passengers” to enjoy a comfortable flight experience, the model team effectively used the space in the fairing to move the “feet” of the “passengers” under the adapter, and opened up 3 “special seats” on the support cabin , Successfully let 41 satellites “board” smoothly. Although the form of the “seat” is relatively new, but a closer look shows that they are all high-quality parts that have been sent to the “passengers” before, which effectively guarantees the safety and reliability of this mission.
In addition, in order to avoid crowded collisions when “getting off the car”, the research and development team of the Eighth Academy ingeniously designed the “drop-off plan” to allow the satellites to separate in an orderly manner. The overall design team divided the 38 satellites on the cylindrical multi-satellite adapter into one group of “passengers” on each floor, a total of 6 groups; the 3 “passengers” on the lower support cabin were taken as the seventh group, and the satellites were carried out in sequence according to the group separate. In addition, this rocket is also equipped with 10 reverse thrust rockets. By turning on the reverse thrust rockets, the distance between each group of satellites is widened to ensure the safety of separation from each other
