Long March 3B/E | Gaofen 4
In geostationary orbit Gaofen 4 will monitor the Earth in the visible light and infrared regions, at a resolution of 50m and 400m respectively for near time civilian applications. The spacecraft is the 4th Gaofen series spacecraft to be launched in China’s High-Definition Earth Observation Satellite (HDEOS) program. The satellite weighs 4600kg, is powered by 2 solar arrays and has an expected lifetime of 8 years.
The Long March 3B / E (G2) (CZ-3B / E) is one of the most successful medium-range launchers and the strongest variant of the CZ-3 series. It was specially developed for the transport of heavy communications satellites into a geostationary transfer orbit. The additional designation "E" stands for a higher payload fairing, stretched boosters and extended fuel tanks at the first stage, over the CZ-3B.
