Gaofen (GF) is a series of Chinese civilian remote sensing satellites for the state-sponsored program China High-definition Earth Observation System (CHEOS).
GF 7 is an optical satellite for mapping purposes for National Administration of Surveying, Mapping and Geoinformation of China (NASMG) similar, but improved, to the earlier ZY-3. It features two camera systems for mapping and surveying and a laser altimeter.
It was launched in November 2019 on a CZ-4B rocket from China's TaiYuan space center.
