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.
