GF-1 (GaoFen-1)

GaoFen-1 (gao fen = high resolution) is the first of a series of high-resolution optical Earth observation satellites of CNSA (China National Space Administration), Beijing, China. GF-1 launched 26th April 2013.

In 2010, the Chinese government approved to implement CHEOS (China High-resolution Earth Observation System), which is an extension of the HDEOS program. The CHEOS series will consist of seven optical/microwave satellites.

GF-1 employs the CAST-2000 bus, it is configured with two 2 m Pan/8 m MS camera and a four 16 m MS medium-resolution and wide-field camera set. GF-1 realizes an integration of imaging capacity at medium and high spatial resolution and with a wide swath, the design life is 5 years with a goal of 8 years.

The revisit frequency of the spacecraft is ≤4 days and the observation range of the mission covers a region from 80ºN to 80ºS. It mainly applies in land resource investigation, mineral resource management, atmospheric and water environment quality monitoring, and natural disaster emergency response and monitoring.
