With the continuous development of science and technology, human beings are more and more lean in pursuit of perfection and better in everything, so no matter in any field, they are constantly exploring and researching. Recently, a nine star arrow has been successfully launched, which represents the progress of China’s aerospace industry. So what’s the significance of the following detailed introduction of the next nine star arrow launch from constellation knowledge?
One arrow and nine stars successfully launched
At 11:22 on December 20, Beijing time, China successfully launched nine satellites, including China Brazil Earth Resource Satellite 04A, Ethiopia micro satellite and tianqin-1 technology test satellite, in the way of “one arrow and nine stars” with long march 4B carrier rocket at Taiyuan Satellite Launch Center.
What is a nine star arrow
China Brazil Earth Resources Satellite 04A is the sixth satellite jointly developed by China and Brazil. It will replace China Brazil Earth Resources Satellite 04 to obtain global high, medium and low resolution optical remote sensing data, laying the foundation for the application of China Brazil Resource Series satellite data to the global high resolution business area, and also for the Brazilian government to realize the transformation of the Amazon tropical rainforest and the national environment Provide high-tech means for chemical monitoring, etc.
What is the significance of a successful launch of nine stars with one arrow
China Brazil Earth Resources Satellite 04A carries three optical payloads, including the wideband panchromatic multispectral camera developed by China, and the multispectral camera and wide field imager developed by Pakistan. Among them, the resolution of wide panchromatic multispectral camera can reach 2 meters, and the width is better than 90 kilometers; the resolution of multispectral camera is 17 meters, and the width is better than 90 kilometers; the resolution of wide field camera is 60 meters, and the width is better than 685 kilometers. On the basis of inheriting the observation elements and data continuity of 04 satellite, the satellite has stronger imaging ability, higher positioning accuracy and side sway ability, which can better meet the urgent needs of the two countries for remote sensing data in the fields of land and resources exploration, land classification, environmental protection monitoring, climate change research, disaster prevention and mitigation, crop classification and yield estimation, and can provide services for Asian, African and Latin American countries.
The reporter learned that the China Brazil Earth Resources Satellite 04A project was organized and implemented by the National Space Administration of China, and the satellite system was jointly developed by the China Academy of space technology and the Brazilian Academy of space technology affiliated to China Aerospace Science and Technology Group Co., Ltd.; the launch, measurement and control were organized and implemented by the China satellite launch, measurement and control system department, and the business measurement and control were in turn in the charge of China and Brazil; the Chinese ground application system China Resource Satellite Application Center and the Institute of remote sensing and digital earth of the Chinese Academy of sciences are responsible, while the Brazilian ground application system is in the charge of the Brazilian Space Institute.
The micro satellite donated to Ethiopia by China is the first man-made earth satellite in Ethiopia, with a mass of about 65kg and a design life of 2 years. It is mainly loaded with multispectral wide-band cameras, which can obtain multispectral remote sensing data in fields such as agriculture, forestry, water conservancy, disaster prevention and mitigation, and support Ethiopia to carry out climate change research.
