Launched on 19 August 2014, GF-2 is equipped with 2 PAN/MS cameras, capable of collecting images with resolution of 0.80 m (nadir) in panchromatic and 3.24 m (nadir) in the multispectral bands on a swath of 45 km.
GF-2 is a follow-on mission of the Gaofen-1 technology demonstration mission, a series of high-resolution optical Earth observation satellites of CNSA (China National Space Administration), Beijing, China. GF-2 is part of the CHEOS (China High Resolution Earth Observation System) family with the objective to provide high accuracy geographical mapping, land and resource surveying, environment change monitoring, near real-time observation for disaster prevention and mitigation, as well as for agriculture and forest estimation.
