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.
