[ 2006-12-25 18:32 ]

据监测数据显示,于12月8日在西昌卫星发射中心发射的“风云二号”D气象卫星,目前运行正常稳定。“风云二号”D星是我国发射的第二颗地球静止轨道气象卫星,它将全面负责预报北京奥运期间天气,特别是奥运会开、闭幕式等大型活动及重要赛事时的天气变化情况,为北京奥运气象保障体系提供准确、及时的服务。

 
          Fengyun-2D (FY-2D)
                 
On-orbit tests show that Fengyun-2D (FY-2D), geostationary orbit meteorological satellite launched earlier this month to provide quality service for the Olympic games, has been functioning properly, the government said on Sunday.

Fengyun-2D, China's second geostationary orbit meteorological satellite, "has been in stable working conditions since the tests began on December 14," the China Meteorological Administration said.

The FY-2D, developed and manufactured by the Shanghai Academy of Spaceflight Technology affiliated to China Aerospace Science and Industry Corp., can observe weather changes around the clock. It is capable of carrying out analysis on the form and structure of clouds and can also analyse data on daytime light.

The satellite, launched on December 8, 2006, is expected to provide better weather forecast services for the Beijing 2008 Olympics.

China will launch another 22 meteorological satellites by 2020,including four more of the Fengyun-2 series, 12 of the Fengyun-3 series and six of Fengyun-4 series.
