  skos:definition """China began its geostationary meteorological satellite FY-2
program in 1980. Through hard work for more than ten years, the
first FY-2 satellite was launched on June 10, 1997 and located
in the geostationary orbit at an altitude of 35800 kilometers
over 105 degrees E. The satellite is a cylinder of 2.1 m by
1.6 m. The attitude of the satellite is spin stabilized with a
speed of 100 rotation/min.

FY-2A is the first geostationary meteorological satellite in
China. It is a spin-stabilized satellite. The main function of
FY-2A is observation. It takes visible, infrared and water vapor
disk images of the Earth hourly. The main payload of FY-2A is a
Visible and Infrared Spin Scan Radiometer (VISSR).

The VISSR takes the Earth and cloud images from the space. A
complete 20° x20° scan covering the full Earth disk can be
accomplished every 30 minutes by means of combination of
satellite spin motion (100 rpm from the west to east) and step
action of the scan mirror (2500 steps from north to south). The
S-VISSR data are retransmitted to user stations via FY-2A during
the VISSR observation.  The stretched VISSR (S-VISSR) data are
the digital image data originated by VISSR on board and
stretched on the Command and Data Acquisition Station (CDAS) in
time. After stretching, the transmission rate of S-VISSR data is
reduced and can be easily received by the users.
