CBERS-2B
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.〔 The third CBERS satellite to fly, it was launched by China in 2007 to replace CBERS-2.〔 CBERS-2B 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.〔〔(【引用サイトリンク】title=CBERS-1, 2 and 2B Description )〕 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 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 High Resolution Camera (HRC) was a panchromatic imager with a resolution of and a swath width of .〔(【引用サイトリンク】title=CBERS-1, 2 and 2B Cameras )〕 HRC replaced the lower-resolution Infrared Multispectral Scanner instrument flown on earlier CBERS satellites.〔 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.〔 The satellite was successfully placed into a sun-synchronous orbit.〔(【引用サイトリンク】title=UCS Satellite Database )〕 CBERS-2B suffered a power system failure on 10 May 2010, leaving it unable to continue operations. As of it remains in orbit, with a perigee of , an apogee of , degrees inclination and a period of minutes. It has a semimajor axis of , and eccentricity of . ==References==
