China–Brazil Earth Resources Satellite 2B (CBERS-2B), also known as Ziyuan I-02B or Ziyuan 1B2, 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.[1] The third CBERS satellite to fly, it was launched by China in 2007 to replace CBERS-2.[3]

CBERS-2B was a 1,450-kilogram (3,200 lb) 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-2B spacecraft consisted of three systems: the Wide Field Imager (WFI) produced visible-light to near-infrared images with a resolution of 260 metres (850 ft) and a swath width of 890 kilometres (550 mi); a high-resolution CCD camera was used for multispectral imaging at a resolution of 20 metres (66 ft) with a swath width of 113 kilometres (70 mi); the third instrument, the High Resolution Camera (HRC) was a panchromatic imager with a resolution of 2.7 metres (8 ft 10 in) and a swath width of 27 kilometres (17 mi).[6] HRC replaced the lower-resolution Infrared Multispectral Scanner instrument flown on earlier CBERS satellites.[1]

A Chang Zheng 4B carrier rocket, operated by the China Academy of Launch Vehicle Technology, was used to launch CBERS-2B. The launch took place at 03:26:13 UTC on 19 September 2007, using Launch Complex 7 at the Taiyuan Satellite Launch Centre.[3] The satellite was successfully placed into a sun-synchronous orbit.[7]

CBERS-2B suffered a power system failure on 10 May 2010, leaving it unable to continue operations. As of 23 August 2014 it remains in orbit, with a perigee of 744 kilometres (462 mi), an apogee of 791 kilometres (492 mi), 98.29 degrees inclination and a period of 100.05 minutes. It has a semimajor axis of 7,138.910 kilometres (4,435.913 mi), and eccentricity of 0.003266.[4]
