Successfully launched from the Xichang Satellite Launch Center, accurately sending the Remote Sensing 39 satellite into the predetermined orbit. This launch is the 500th launch of the Long March series of launch vehicles, once again setting a new height for China’s aerospace industry.
“Long March 2D” is a medium-sized two-stage room-temperature liquid launch vehicle developed by the Eighth Institute of Aerospace Science and Technology. The first and second stages are powered by dinitrogen tetroxide/uniform dimethylhydrazine propellant. The arrow is 41 meters long, with a diameter of 3.35 meters for both the first and second levels, a take-off mass of 250 tons, a take-off thrust of 302 tons, a low-Earth orbit (LEO) transport capacity of 4.0 tons, a 500-kilometer sun-synchronous orbit (SSO) transport capacity of 1.5 tons, and 700 Kilometer sun-synchronous orbit has a transport capacity of 1.3 tons. This rocket uses an extended fairing with a diameter of 3.35 meters, and the height of the entire rocket is increased by several meters. At present, the rocket’s effective working time at the launch site has been shortened to 10 days, making it one of the rocket models with the shortest working cycle at the domestic launch site.
It took 37 years for the Long March series rockets to achieve the first 100 launches, the second 100 launches in 7 and a half years, the third 100 launches in more than 4 years, and the fourth 100 launches in 2 years and 9 months. The fifth 100 times only took 2 years. From scratch, from small to large, from weak to strong, from the first time to the 500th time, China Aerospace has demonstrated China’s rocket speed to the world……
On the 9th November 2023 in CNSA _China National Space Administration -China – People’s Republic of China 0403 hours Hong Kong –Beijing Time China- People’s Republic of China launch the Chang Zheng – Long march 3B Carrier Rocket launching from station form Xichang Satellite Launch Center Sichuan Province….. in which中国 successfully launched the ChinaSat 6E satellite# At 19:23 on November 9, the Long March 3B carrier rocket lifted the ChinaSat 6E satellite into space at the Xichang Satellite Launch Center, and then sent the satellite into the predetermined orbit. The launch mission was achieved A complete success.
The ChinaSat 6E satellite was developed by the Fifth Academy of China Aerospace Science and Technology Corporation. It adopts the Dongfanghong 4 enhanced satellite platform independently developed by my country. The satellite is equipped with C, Ku and other multi-band broadcast communication payloads, and is the first to use the domestic No. Fourth generation digital transparency processing technology. This satellite is my country’s new generation of dedicated transmission satellite for radio and television. It will succeed the ChinaSat 6B satellite business and undertake the mission of radio and television broadcasting. At the same time, the satellite will realize the on-orbit demonstration application of my country’s fourth-generation digital transparent processing technology and Ku high-throughput payload for the first time.
The Long March 3B carrier rocket is developed by the First Academy of China Aerospace Science and Technology Corporation. This rocket is the first application of the special development and implementation of the “double improvement” of the Changsanjia series model’s carrying capacity and reliability, which is a milestone in the development of the model. The geostationary transfer orbit rocket carrying capacity of this rocket reaches 5.55 tons. The whole rocket has a total of 74 improvements, including 52 first-flight improvement projects. This mission is developed and organized and managed based on the first-flight model.
After completing the on-orbit test, the ChinaSat 6E satellite will be handed over to China Satcom, a subsidiary of China Aerospace Science and Technology Corporation, for operation and management. It is planned to be located at 115.5 degrees east longitude. Its radio and television resources mainly cover China, Southeast Asia, Australia and other regions, and its communication resources mainly cover China’s land and territorial waters, Central Asia and South Asia. It will provide important support for the construction of the “Belt and Road”, new infrastructure construction and the construction of Digital China. This launch is the 496th launch of the Long March series of launch vehicles.
As a “new star” for broadcasting, Vimicro’s 6E satellite can not only provide services for my country’s central and local 95 channels of satellite TV and 213 channels of digital audio broadcasting, but also expand satellite functions with a number of “new” capabilities, adding 8K ultra-high-definition High-definition business, user viewing range and user viewing quality will be greatly improved, helping my country’s radio and television broadcasting industry to flourish.
According to the designer of the ChinaSat 6E satellite from the Fifth Academy, in order to meet users’ high requirements for satellite coverage performance indicators, the development team adopted a variety of methods to reduce surface errors and improve antenna radiation characteristics; it also adopted power synthesis technology to meet the requirements for 8K ultra-high definition. Video transmission business requirements. At the same time, the development team configured four high-frequency bandwidth channels for the satellite, which increased the load power and significantly improved the data transmission rate. In addition, the current C-band continuous wave maximum output power traveling wave tube amplifier is used, which increases the power of the ChinaSat 6B satellite by 31%. For radio and television broadcasting projects, we will continue to improve the robustness of the platform by improving satellite transfer orbit autonomy and fault recovery capabilities, and selecting the best key products
[ Chang Zheng- Long March 3B carrier Rocket, carrying capacity digs 50kg geostationary transfer orbit carrying capacity increased from 5.5 tons to 5.55 tons] On November 9, the Long March 3B carrier rocket lifted the ChinaSat 6E satellite into space, and the mission was a complete success. The “upgraded version” of the Changsha 3A series rocket successfully made its first flight, achieving the goal of “double improvement”. The Long March 3B geostationary transfer orbit carrying capacity has been increased from 5.5 tons to 5.55 tons; there are 74 technical improvement projects, including 52 first flight improvement projects; the improvements involve all rocket systems.
According to Zhang Tao, deputy chief designer of the Changsanjia series rockets, the rocket has also helped improve the rocket’s carrying capacity by 50% by overall optimizing the flight trajectory plan, canceling the terminal velocity correction, optimizing the pre-cooling flow of the three-stage rocket engine, and canceling the booster cylinder in the engine. Kilogram.
