On Monday, China has successfully launched a mapping satellite into orbit at 3.10 am EDT. The liftoff of the Tianhui-1C took place from the Launch Area 4 at the Jiuquan satellite launch centre in Gansu province.
The satellite has been safely placed into a Sun-synchronous orbit (SSO). After around half an hour of the liftoff, Chinese media unveiled the news of the launch. The satellite has been made by the Hangtian Dongfanghong Weixing Corporation and the Chinese Academy of Space Technology (CAST).
It is an earth observation satellite that will be used for purposes like science experiments, land resources surveys, mapping, disaster relief and crop yield estimation. The satellite has two solar panels for energy generation purpose and they will be stored on onboard batteries.
It is also equipped with a 3-D camera and a CCD camera having ground resolution of 5 meters. Multi-spectrum camera is also present on the spacecraft and it has ground resolution of 10 meters. These cameras have the ability to produce an image of 60 kilometers wide.
On August 24, 2010, China launched its first Tianhui-1 satellite. After two years on May 6, 2012, Tianhui-1B was delivered into orbit. All these satellites are part of the Ziyuan program, which covers civil and military earth observation and remote sensing programs.
All the three satellites have different roles to play like the Ziyuan-1 program focus on earth resources. The second one was used for aerial monitoring and the Ziyuan-3 will be meant for stereo imaging.
