Is Fengyun 2 still in use?

On April 1 day, Fengyun-2 F star, which is located over the equator of East longitude 1 12, officially withdrew from business operation. During the operating period of 10, Star F * * * made 107 encrypted observations and obtained 14. More than 40,000 cloud images have effectively improved the emergency monitoring ability of typhoons, strong convection and other disasters, and made important contributions to China's economic and social development and Asian meteorological observation.

Star F is the first star of Fengyun-2 in batch 03 and was successfully launched on 20 12 13. Its scanning radiometer, space environment monitor and other equipment further improve the accuracy of satellite earth detection and space weather monitoring performance, and also enable F-star to provide more flexible high-frequency sub-regional encrypted observation for the target area according to special needs.

Xu Jianmin, an academician of China Academy of Engineering, previously introduced that compared with E-Star Fengyun-2, the level of clouds in the F nebula map is richer, and the clearer texture features on the cloud surface are more conducive to forecasters to identify the weather; In quantitative application, the stray light of the image is effectively suppressed, and the accuracy of radiation calibration and quantitative products is improved.

During the period of 10, F-Star played an important role in disaster prevention and mitigation and ensured economic and social development. Its observation data and products are widely used in meteorology, ocean, agriculture and rural areas, forestry, water conservancy, transportation, aviation and other fields. In weather processes such as Typhoon No.9 rammasun in 20 14, heavy precipitation in Beijing, Tianjin and Hebei on July 6-7, 20 14, Nanjing Youth Olympic Games in 2014, G20 Hangzhou Summit in 20 16, and the 20th anniversary celebration of Macao's return to the motherland in 20 19, etc.

Fengyun-2 meteorological satellite (FY-2) is the first generation geosynchronous orbit meteorological satellite developed in China, which is complementary to polar orbit meteorological satellite and forms the application system of meteorological satellite in China. Fengyun-2 satellite is composed of two experimental satellites (Fengyun -2A satellite and Fengyun -2B satellite) and four operational satellites (Fengyun -2C satellite, Fengyun -2D satellite, Fengyun -2E satellite and Fengyun -2F satellite). Its functions are to obtain visible light cloud pictures, day and night infrared cloud pictures and water vapor distribution maps, fax weather maps, and collect meteorological monitoring data from meteorological, hydrological and marine data collection platforms at home and abroad.

On June 5th, 20107, China Fengyun-2 H star was successfully launched by Long March 3A carrier rocket in xichang satellite launch center.

After the establishment of the emergency support mechanism for Fengyun satellite's international users, Vietnam and the Philippines applied to start the emergency support mechanism three times in response to the super typhoons Mangosteen and Yutu, and F star started encrypted observation and provided products in time. Later, they received letters from Viet Nam and the Philippines thanking the government of China.

F satellite will be transferred to the on-orbit backup state after "decommissioning", and the National Satellite Meteorological Center will continue to do a good job in satellite state monitoring and orbit management to protect the space frequency resources of geostationary meteorological satellites.

20 16 may 19, it was learned from the 7th annual meeting of China's satellite navigation that China is formulating the People's Republic of China (PRC) satellite navigation regulations, which has been included in the legislative work plan of the State Council in 2016.

2065438+On May 23rd, 2007, Ran Chengqi, director of China Satellite Navigation System Management Office, revealed at the opening ceremony of the 8th China Satellite Navigation Academic Annual Conference that the research and drafting of People's Republic of China (PRC) Satellite Navigation Regulations had made positive progress, and the first draft had been completed, which would soon form a draft for comments.

The drafting group of People's Republic of China (PRC) Satellite Navigation Regulations includes central and national ministries, as well as important users of civil aviation, electric power, public security and experts from key enterprise associations. After extensive research and demonstration, a national academic seminar was held and positive progress was made.

In June 2020165438+1October, the 11th China Satellite Navigation Annual Conference "H02 Policy and Regulation, Standardization and Intellectual Property Forum" was held in Chengdu Century City International Conference Center. At this forum, Researcher Yang, Executive Director of Beidou Policy and Regulation Research Center, introduced the latest progress in drafting the Regulations on Satellite Navigation in People's Republic of China (PRC). At present, the Regulations of People's Republic of China (PRC) on Satellite Navigation has been solicited for comments, and it is being revised and improved to be submitted.

Legal basis:

Article 1 of the Interim Measures for the Administration of Civil Satellite Engineering

In order to standardize the management of civil satellite projects, strengthen the supervision of the aerospace industry, implement the requirements of the State Council's "Outline of the National Medium and Long-term Development Plan for Civil Space Infrastructure (20 15-2025)", and give full play to the investment and application benefits of satellite projects, these measures are formulated.

second

These Measures shall apply to civil scientific research satellites, operational satellites and other engineering projects that use all or part of the central financial funds and are approved by the State Council or relevant state departments.

essay

Follow the principles of scientific justice, standardization, high efficiency, clear rights and responsibilities, and practical results, strengthen process control and milestone evaluation, unify development and construction processes, quality supervision and management, and standard systems, and realize the healthy and coordinated development of space and ground resources.

Article 4

Civil satellite engineering generally consists of six systems: satellite system, launch vehicle system, launch site system, measurement and control system, ground system and application system, which are generally divided into stages of project demonstration, scheme, initial sample, normal sample, on-orbit test delivery, summary and evaluation. Satellite engineering with high technical maturity can simplify the corresponding development process.
