On 20th May 2022 1830 Hours Hong Kong SAR- Beijing time , the Belt and Road Initiative CNSA –China National Space Administration launching from Jiuquan Satellite Launch Center – Inner Mongolia –China – People’s Republic of China, successfully deployed three Communications Satellites with the Chang Zheng – Long March 2C carrier rocket on the satellite successfully entered the predetermined orbit….
China – People’s Republic of China successfully launched three low-orbit communication test satellites At 18:30 on May 20, 2022, Beijing time, China launched the Chang Zheng – Long March 2C carrier rocket yao 53 carrier rocket at the Jiuquan Satellite Launch Center. Deploying the three satellites At the upper level of the fifth stage, three low-orbit communication test satellites were successfully sent into the scheduled low-Earth orbit in the way of “one carrier rocket and three satellites”, and the launch mission was a complete success.
The low-orbit communication test satellites launched this time are mainly used for on-orbit communication technology test verification. Two of them are developed by Changguang Satellite Technology Co., Ltd. and the other is developed by the Fifth Academy of China Aerospace Science and Technology Corporation.
Chang Zheng – Long March 2C carrier rocket will also perform a launch mission in Xichang in the near future This year, the Chang Er C rocket will be transferred to multiple launch centers for high-density launches. According to Li Jun, the chief designer of the Chang Zheng – Long March 2C carrier rocket, the development team is currently working in Jiuquan and Xichang. A launch center performs the launch mission.
As a “Gold Medal Veteran”, the Chang Zheng – Long March 2C carrier rocket has mature technology and a stable state, but the development team is not satisfied with this, and always adheres to the sense of innovation, so that the rocket’s capabilities from the overall to the system, design and simulation verification have been significantly improved. Especially in recent years, the Chang Zheng – Long March 2C carrier rocket has successively applied the two-way correction of the ballistic high-altitude wind, the quasi-real-time secondary compensation before the launch, and the active load shedding control, which significantly reduces the aerodynamic load in flight and improves the flight safety and launch probability. , which can better cope with high-density emission requirements.
The Rocket Academy has also planned in advance to allocate resources closely around the successful launch, so as to realize the allocation of products between tasks and models and the reuse of personnel in the launch center. For example, in the Jiuquan Satellite Launch Center, the Chang Zheng – Long March 2C carrier rocket and Chang Zheng –Long March 2F Carrier rockets were launched in parallel. The two team’s reused personnel from multiple positions including the control and command post, which effectively reduced the number of personnel entering the site.

In the face of a more compact production test cycle, the R&D team completely eliminated the time loss of “idling” through the “transparency” of the product matching process, and comprehensively applied and continuously iteratively optimized the integrated documents in the final assembly and final test process to achieve quality. Control one-time alignment in place to ensure high-quality launch
This mission is the fourth launch of the upper stage of Expedition 1 S. The previous three launches were on October 9, 2018, August 24, 2021, and November 3, 2021.
This launch is the 421st launch of the Long March series of carrier rockets.
