GF-7 SATELLITE

65 cm, Bi-stereoscopic, Optical, Laser Altimeter

GF-7 (short for Gaofen-7) was launched on November 3, 2019. It is a very high-resolution optical imaging satellite, and collects bi-stereoscopic and panchromatic-multispectral imagery. It is also equipped one laser altimeter. The satellite collects overlap images and enables 1:10,000-scale stereoscopic mapping. Its laser altimeter provides great supports in mapping difficult geographic terrains. The satellite mainly applies in monitoring land resources, basic mapping, and investigating globally geographic features.
