China entered the "era of submeter resolution satellites"
On August 19, China launched its second high-resolution Earth remote sensing (ERS) satellite. Gaofen-2 was launched at 11:15 am from the Taiyuan cosmodrome (Shanxi province, North China), opening for the first time for the country the possibility of obtaining high spatial resolution data up to 1 m using the Chinese optical ERS spacecraft.
"The successful launch of the Gaofen-2 satellite is an important interim result in the implementation of the Gaofen target program. This is a milestone that indicates our country's entry into the" era of sub-meter resolution satellites, "said the deputy head of the State Department of Defense Science, Technology and Industry Zhang Jianhua.
Gaofen is one of China's 16 major science and technology development programs scheduled for 2006-2020. The first satellite within its framework - Gaofen -1 with a resolution of 2 m in panchromatic and 8 m in multispectral modes - was launched on April 26, 2013. More than a dozen ministries and departments in the field of land and subsoil use, ecology, agriculture and others use the results of the satellite in their activities.
It is expected that the commissioning of another satellite of this system will facilitate the use of high-resolution satellite data, in particular in such areas as dynamic monitoring of land use, urban and rural construction, design and construction of transport networks, study of the state of forest resources, monitoring of desertification and etc.
