Three aerospace centers in Beijing, northwest China's Jiuquan
and north China's Xi'an jointly watch over China's second manned
space flight, said an expert Thursday.
Sun Baosheng, deputy chief designer of the monitoring and
telecommunications system of the manned space project, said the
Beijing Aerospace Command and Control Center, Jiuquan Satellite
Launch Center and Xi'an Satellite Track and Control Center jointly
realize real time monitoring over Shenzhou VI.
The Jiuquan Center is mainly responsible for data collecting,
processing and analyzing, decision-making and commanding during the
space capsule's ascend, while the Beijing Center watches over most
of the processes from the capsule's entering into orbit till
return.
A bit like a backup of the Beijing Center, the Xi'an Center
calculates some key monitoring data of the craft and compare them
to Beijing Center's calculation to ensure accuracy.
It also performs remote supervision over monitoring stations to
ensure they track and control the craft effectively, Sun said.
