Gaofen (GF) is a series of Chinese civilian remote sensing satellites for the state-sponsored program China High-definition Earth Observation System (CHEOS).

GF 1-02, 03, 04 are optical satellites with a 2 m resolution pan-chromatic camera and a 8 m resolution multi-spectral camera.

These satellites are similar to Gaofen 1, but have the 16 m camera deleted and feaure a smaller bus, allowing three satellites to be launched at a time.
