Satellite Launched for Olympic Weather Forecasts
Adjust font size:

China successfully launched its second geostationary orbit meteorological satellite, Fengyun-2D (FY-2D), on Friday to provide better weather forecast services for the Beijing 2008 Olympic Games.

The FY-2D satellite was launched into the target orbit at 8:53 AM aboard a Long March-3A carrier rocket from the Xichang Satellite Launch Center in southwest China's Sichuan Province.

"The satellite will monitor weather changes at all the Beijing 2008 Olympic Games venues," said Li Qin, chief designer of the FY-2D.

"The FY-2D will provide accurate and timely information about weather changes to help us with weather forecasts during the Beijing 2008 Olympic Games, especially the opening and closing ceremony and important contests," he said.

The satellite separated from the rocket about 24 minutes after lift-off and then successfully entered the geosynchronous transfer orbit, according to the satellite monitoring center in Xi'an.

This launch is the eleventh flight of the LM-3A carrier rocket and all11 flights have been successful.

"The LM-3A has now entered a phase of steady commercial operation," said Li Jinghong, deputy designer of the rocket.

China started developing the LM-3A in March 1986. At its first launch on Feb. 8, 1994, the LM-3A carrier rocket successfully sent the Shijian-4 satellite and a dummy satellite into orbit.

The 52.52-meter-long LM-3A is mainly used to launch satellites to geosynchronous transfer orbit. With a payload of 2.6 tons, it can transport several satellites at the same time.

"We are continuing to improve the technology and add equipment. For the launch of the FY-2D we added 48-channel GPS," Li said.

The 1.39-ton FY-2D satellite will take up a position in the next few days at 86.5 degrees east longitude right above the equator.

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 infrared nephanalysis of the form and structure of clouds and can also analyse data about visible daytime light.

The Fengyun-2D will form a twin-star observation system with Fengyun-2C, China's first geostationary orbit weather satellite which went into orbit on Oct. 19, 2004, according to the China Meteorological Administration (CMA).

The two satellites have their own observation tasks, but can also replace each other if one of them malfunctions, the CMA said.

FY-2D will help the CMA bolster weather monitoring information from western China where cold fronts and sandstorms usually begin.

"The Fengyun-2D will expand our geostationary weather observation range and improve the forecast and monitoring of disaster weather," said Yang Jun, director of the National Satellite Meteorological Center.
