Ziyuan 3 (Chinese: 资源 三号) is a Chinese earth observation satellite owned by the Ministry of Land and Resources.
It was placed in sun-synchronous orbit on January 9, 2012 at 03:17 UTC by a Long March 4 launcher from the Taiyuan Cosmodrome . The rocket also carried the 28 kg Luxembourg satellite VesselSat 2 , which is to be used to support the latest constellation of ORBCOMM satellites.
Planning by the responsible ministry began in 2005, and in 2008 the project was officially approved by the Chinese government. Technical development began in 2009 at the China Academy of Space Technology (CAST). In terms of design and tasks, the satellite corresponds to the military Tianhui 1 and is based on the same satellite bus as its three predecessors in the Ziyuan 2 series , which were launched on September 1, 2000.
The three-axis stabilized satellite is equipped with three high-resolution black and white cameras and a infrared - multispectral camera equipped and intended for cartography, for observation of land resources, to help in reducing damage caused by natural disasters as well as to assist in agriculture and many other areas are used. It can fly over any point on earth again within 5 days and should only be used for civil purposes. The entire area between 84 ° north and 84 ° south is flown over within 59 days. Two of the three cameras have a resolution of 3.5 m and a swath width of 52.3 km, while the third has a resolution of 2.1 m and a swath width of 51.1 km. The infrared camera has a resolution of 6.0 m and a swath width of 51.0 km. The energy is supplied via two solar panels, each with a 3 m span. Ziyuan 3 has a planned lifespan of five years.
