CBERS-2
China–Brazil Earth Resources Satellite 2, also known as Ziyuan I-02 or Ziyuan 1B, was a remote sensing satellite operated as part of the China–Brazil Earth Resources Satellite programme between the China Centre for Resources Satellite Data and Application and Brazil's National Institute for Space Research. The second CBERS satellite to fly, it was launched by China in 2003 to replace CBERS-1.
CBERS-2 was a spacecraft built by the China Academy of Space Technology and based on the Phoenix-Eye 1 satellite bus. The spacecraft was powered by a single solar array, which provided 1,100 watts of electricity for the satellite's systems. The instrument suite aboard the CBERS-2 spacecraft consisted of three systems: the Wide Field Imager produced visible-light to near-infrared images with a resolution of and a swath width of ; a high-resolution CCD camera was used for multispectral imaging at a resolution of with a swath width of ; the third instrument, the Infrared Multispectral Scanner, had a resolution of and a swath width of.
A Chang Zheng 4B carrier rocket, operated by the China Academy of Launch Vehicle Technology, was used to launch CBERS-2. The launch took place at 03:16 UTC on 21 October 2003, using Launch Complex 7 at the Taiyuan Satellite Launch Centre. The satellite was successfully placed into a sun-synchronous orbit.
Following the launch of CBERS-2B in 2007, CBERS-2 was retired from service. As of 1 December 2013, the dericict satellite remains in orbit, with a perigee of, an apogee of, 98.17 degrees inclination and a period of 100.33 minutes. Its orbit has a semimajor axis of, and eccentricity of 0.0001886.
