China–Brazil Earth Resources Satellite 2 (CBERS-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 program between the Chinese Center for Resources Satellite Data and Application and Brazilian National Institute for Space Research.[1] The second CBERS satellite to fly, it was launched by China in 2003 to replace CBERS-1.[3]

CBERS-2 was a 1450adj=onNaNadj=on spacecraft built by the China Academy of Space Technology and based on the Phoenix-Eye 1 satellite bus.[1] The spacecraft was powered by a single solar array, which provided 1,100 watts of electricity for the satellite's systems.[2] [5] The instrument suite aboard the CBERS-2 spacecraft consisted of three systems: the Wide Field Imager (WFI) produced visible-light to near-infrared images with a resolution of 260m (850feet) and a swath width of 890km (550miles); a high-resolution CCD camera was used for multispectral imaging at a resolution of 20m (70feet) with a swath width of 113km (70miles); the third instrument, the Infrared Multispectral Scanner (IMS), had a resolution of and a swath width of 120km (80miles).[6]

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 Center.[3] The satellite was successfully placed into a Sun-synchronous orbit.[7]

Following the launch of CBERS-2B in 2007, CBERS-2 was retired from service.[2] As of 1 December 2013, the dericict satellite remains in orbit, with a perigee of 780km (490miles), an apogee of 782km (486miles), 98.17 degrees inclination and a period of 100.33 minutes. Its orbit has a semimajor axis of 7152.64km (4,444.44miles), and eccentricity of 0.0001886.[4]
