The international advanced level of Fengyun meteorological satellite

On June 5438+1October 65438+February, 2007, when China Meteorological Bureau successfully obtained the first set of images of FY-2 2 D meteorological satellite, experts evaluated that the development capability of FY-2 meteorological satellite in China had reached the international advanced level. So far, China has successfully launched eight meteorological satellites. At present, the running D satellite and Fengyun-2 C meteorological satellite * * * have realized on-orbit backup, which has enabled China to have the observation ability of double-star networking. Qin Dahe, director of China Meteorological Bureau, said that the application and service level of meteorological satellites will be further improved, and the fields of satellite applications and services will be actively expanded to enjoy satellite data.

The observation range of the binary satellite extends to the west by nearly 20 longitudes, which can provide guarantee for the Olympic meteorological service.

Above the equator, about 36,000 kilometers away from the Earth, Stars D and C overlook the land of China. According to experts from China Meteorological Bureau, after being put into operation, Star D and Star C will form a continuous observation of the maximum range of China 15 minutes, and the observation range will extend to the west by nearly 20 longitudes. Double-star network observation will not only further expand the observation area and realize short-term high-frequency monitoring of disastrous weather, but also realize three-dimensional imaging of key areas, thus minimizing the losses caused by disastrous weather.

Yang Jun, director of the National Satellite Meteorological Center of China Meteorological Bureau, said that during the 2008 Beijing Olympic Games, the D-star will reach its best state, providing a solid guarantee for the Olympic meteorological service.

Fill the gaps in meteorological data and find disaster weather earlier.

China is located in the mid-latitude westerly belt, and the cold Siberian air in the south and the warm and humid air in the Indian Ocean in the north have a significant impact on the weather in China. Experts said that the observation data of D-star will fill the data gap in the western Indian Ocean and greatly improve the prediction of summer monsoon. Before Fengyun-2 was put into operation, there was no stable static meteorological data source in the vast central and western regions of China for a long time.

After D-Star is put into operation, the monitoring range of future weather system will be extended to the East Africa to the Red Sea, so as to find the disastrous weather system earlier and improve the forecast time limit. The high-frequency continuous observation of China by binary satellites can effectively monitor and warn the occurrence, development and intensity changes of disastrous weather systems such as typhoon, rainstorm and strong convection.

Fengyun family is growing day by day and will launch several meteorological satellites.

Fengyun-2 meteorological satellite D was successfully launched in xichang satellite launch center, China on February 8, 2006, covering the whole Asian continent, Indian Ocean and Western Pacific. This satellite was developed by China Aerospace Science and Technology Corporation. The ground application system of Fengyun-2 meteorological satellite was built by China Meteorological Bureau, and China has completely independent intellectual property rights.

China began to develop its own meteorological satellite in the early 1970s, and successfully launched the first meteorological satellite "Fengyun-1" on 1988. With the successful launch of Star D, China has successfully sent eight meteorological satellites into space. These include four Fengyun-1 polar orbit meteorological satellites and four Fengyun-2 geostationary orbit meteorological satellites.

Yang Jun revealed that in the next few years, China will launch E, F, G and H satellites of Fengyun-2 one after another. Before 2008, launch the first Fengyun-3 meteorological satellite; Fengyun-4 series meteorological satellites will also enter the model project during the Eleventh Five-Year Plan period.

Satellite data and products benefit neighboring countries and the world.

China Meteorological Bureau is actively doing a good job in sharing satellite data and products, establishing Fengyun meteorological satellite data broadcasting system, and presenting Fengyun meteorological satellite data broadcasting system receiving station to signatory countries of the Asia-Pacific Space Cooperation Organization together with the National Space Administration, so that Fengyun meteorological satellite data can benefit countries in the region.

At present, China meteorological satellite is playing an increasingly important role in the world. A large number of international users directly receive or use China Fengyun meteorological satellite data. Dr. Cirman, President of the World Meteorological Organization, spoke highly of China Fengyun Satellite's important contribution to neighboring countries and the world, as well as its data disclosure policy.
