Ziyuan 3-01 or ZY 3-01 (Chinese: 资源三号 meaning Resources 3) is a Chinese Earth observation satellite launched in January 2012. It is a high-resolution imaging satellite operated by the Ministry of Land and Resources of the People's Republic of China.
Spacecraft
The Ziyuan 3 satellite was constructed by the China's China Academy of Space Technology (CAST), and carries three cameras produced by the Changchun Institute of Optics, Fine Machinery and Physics. A camera aligned normal to the Earth's surface will produce images with a spatial resolution of 2.5 metres (8 ft 2 in), whilst the other two, offset at 22° forward and aft, have spatial resolutions of 4.0 metres (13.1 ft). In addition to the three cameras, Ziyuan-3 carries an infrared multispectral spectrometer, with a spectral resolution of 6.0 metres (19.7 ft). The satellite is used to provide imagery to monitor resources, land use and ecology, and for use in urban planning and disaster management. It had a mass at launch of 2,630 kilograms (5,800 lb). The satellite has a planned operational lifetime of 4 years with a possible extension to 5 years.
Launch
Ziyuan 3 was launched by a Long March 4B carrier rocket, flying from Launch Complex 9 at the Taiyuan Satellite Launch Center. The launch occurred at 03:17:00 UTC on 9 January 2012, and was the first orbital launch of the year. VesselSat-2 was launched as a secondary payload on the same rocket.
