Fengyun 2A



China began its geostationay meteorological satellite FY-2 program in 1980. Feng Yun 2 was built by the Shanghai Institute of Satellite Engineering. The spin-stabilized spacecraft was quite similar to the Japanese GMS-5 satellite originally built by Hughes. The FY-2 was operationally similar to GMS with high resolution stretched VISSR data (5 km IR, 5 km WV, 1.25 km VIS), low resolution Wefax (analog), DCP capability and a new digital S-band fax service (CCITT G3) for domestic distribution of charts and imagery. The attitude of the satellite was spin stabilized with a speed of 100 rotation/min. The spacecraft was slightly more massive than PRC's DFH-2 communications satellite. The Feng Yun 2 spacecraft bus diameter was 2.1 m, and the total height on-station was about 4.5 m.

In 1994 the long-awaited Feng Yun 2 GEO meteorological spacecraft was to be launched and positioned at 105 deg E. The first FY-2 satellite was undergoing final check-out on April 2, 1994 before being mated to its launch vehicle when a fire and explosion erupted, destroying the vehicle, killing one worker, and injuring 20 or more others. Feng Yun 2B was launched on June 10, 1997 to 105 deg E longitude on a CZ-3 booster from Xichang, and the satellite began regular service late in 1997. On April 8, 1998, FY-2B ceased transmission of images due to a problem with the S-band antenna on the spacecraft.
