5) Manned spacecrafts
China has successfully completed five flights under
its Shenzhou manned spaceships program:
a) In March 2002, Shenzhou III flied with a CMODIS sensor
at the altitude of 343¡À5km, with a ground resolution
of 400-500m, swath width of 650-700km and 34 spectral
bands ranging from 0.4 to 12.5 ¦Ìm.
b) Shenzhou IV was launched in December 2002, on-boarded
with a microwave sensor combination of a radiometer,
a radar altimeter and a scatterometer.
c) After successful returning of the first China manned
spacecraft Shenzhou V in October 2003, scientific experiment
payloads, including Earth observation sensors, are remained
on the orbit.

6) Satellite ground receiving and processing
system
China¡¯s operational remote sensing satellite data service
network comprises the China Remote Sensing Satellite
Ground Station (China RSGS), China Center for Resource
Satellite Data and Applications (CRESDA), National Satellite
Meteorological Center (NSMCC) and National Satellite
Ocean Application Service (NSOAS).
Established in 1986, China RSGS is now with the capability
to receive and process data from satellites of LANDSAT¡¢SPOT¡¢RADARSAT-1¡¢ERS-1/2¡¢EROS
and CBERS. The station serves more than 600 users around
the world.
China developed its own meteorological satellite receiving
stations in Beijing, Guangzhou and Urumchi for both
polar orbiting and geostationary meteorological satellites.
The marine satellite ground application system is composed
of Beijing and Sanya stations. It is also notable that
several MODIS ground-receiving stations were also built
in many academic and education institutions in China.
In October 2002, the first remote sensing radiation
calibration site of China was set up in Gansu Province.
Through established cooperation with the White Sands
Test Facility of USA and the Toulouse calibration site
of France, it indicates a new progress of China in satellite
remote sensing calibration and validation, and in supporting
quantitative analysis and applications.
