Gaofen 7



Chinese media is referring to the new Earth observation satellite as playing an important role in land surveying and mapping, urban and rural construction and statistical investigation, according to the China National Space Administration (CNSA).

The new satellite was developed by the Chinese Academy of Aerospace Science and Technology Group Co., Ltd. and the satellite will be mainly used by the Ministry of Natural Resources, the Ministry of Housing and Urban-Rural Development and the National Bureau of Statistics.

The development of the Gaofen-7 has achieved a breakthrough in sub-meter level 3D mapping camera technology, meeting the highest mapping accuracy requirement among the Gaofen series Earth observation satellites. The satellite can obtain high-resolution optical 3D observation data and high-precision laser altimetry data and can realize 1:10,000 scale satellite 3D mapping for civil use in China and will meet the needs of users in basic mapping, global geographic information, monitoring and evaluation in urban and rural construction, agricultural survey and statistics, etc.

The new satellite will work together with other Gaofen satellites to form an Earth observation system with high resolution and high positioning accuracy, which will help promote international sci-tech industrial cooperation through data sharing and support the Belt and Road initiative.

Gaofen (“High Resolution”) is a series of civilian Earth observation satellites developed and launched for the state-sponsored program China High-definition Earth Observation System (CHEOS).
