Gaofen-1 is the first high-resolution optoelectronic satellite operated by the China National Space Administration (CNSA). The satellite was launched on the 26th of April 2013 from the Jiuquan cosmodrome in north-western China. Gaofen-1 is a part of the HDEOS (High-Definition Earth Observation Satellite) program, which main goal is to provide Chinese governmental and commercial organizations with close-to-real-time imagery.
