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

How did “41 satellites with one arrow” come true this time? What’s the point? Li Feng, director of the satellite operation and management technology research office of Chang Guang Satellite Technology Co., Ltd., gave the answer in an exclusive interview with China Jilin Net!
“The launch of ‘One Carrier Rocket 41 Satellites’ poses a huge challenge to the transportation and management system. In the past, a maximum of 16 satellites were launched at one time, but this time the number has reached nearly three times that of the maximum one, and it involves multiple satellite models. For measurement and control , data transmission resources, software system development, and personnel requirements are all higher. In order to do a good job in the operation and management of 41 satellites, the colleagues in the Satellite Operation and Management Technology Research Office started the preparation work at the end of last year, and the internal and external coordination of the company , docking, and recently successfully completed the system development and the joint test of the three-wheel operation and management system, involving 3 large software systems, 4 satellite models, 41 satellites, and 50 sets of antenna equipment, and confirmed the functions, performance and interfaces of each system Matching situation. The 41 satellites launched this time include 8 Jilin-1 Gaofen 03D satellites and 30 Gaofen 06A series satellites. Among them, the weight of the Gaofen 06A single satellite has been successfully reduced to 20kg, and its performance indicators are still very advanced.
Li Feng said, “During the satellite-rocket separation stage, the 41 satellites were separated seven times successively. The separation time of each group of satellites lasted for three to five seconds. . This launch has put forward higher requirements for both satellites and rockets, including separation timing and control of satellite force and torque, so as to ensure that each satellite can enter the predetermined orbit smoothly and safely. “
After the 41 satellites launched this time (including 36 “Jilin-1” satellite constellation networking remote sensing satellites) are in orbit, they will form a network with the 72 “Jilin-1” satellites in orbit. So far, “Jilin-1” “The number of satellites in orbit has increased to 108, marking that the “Jilin-1” satellite constellation network project has successfully achieved the phased goal of “Hundred Stars Flying into the Sky”
