GF-7 (GaoFen-7)

GF-7 satellite was successfully launched on 3 Nov 2019. Its lead user is the Ministry of Natural Resources of P. R. China (MNR), and it also serves other users, such as Ministry of Housing and  Urban-Rural Development of P.R.China(MOHURD) and the National Bureau of Statistics(NBS).

GF-7 satellite runs on the sun-synchronous orbit and has a designed life of 8 years. The two-line stereo camera can effectively obtain 20 km-width panchromatic stereo images with resolution  better than 0.8m and 3.2m-resolution multispectral images; the equipped two-beam laser  altimeter can perform Earth observation at 3Hz observation frequency, with ground footprint diameter less than 30m, and acquire full waveform data at a sampling frequency higher tan 1 GHz.  Through the composite mapping mode of stereo camera and laser altimeter, the satellite realizes  1:10000-scale stereo mapping, serving the application needs of natural resource survey  monitoring, basic surveying and mapping, and global geo-information resource construction, and  providing high-precision satellite remote sensing images for the fields of housing and urban rural  development as well as national survey statistics.
