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

Spacecraft

[edit]

CBERS-2B was a 1,450-kilogram (3,200-pound) 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 1100 watts of electricity for the satellite's systems.[4][5] The 1.8 m x 2.0 m x 2.2 m, triaxially-stabilized spacecraft carries a low 20 m resolution, and a higher 2.5 m resolution camera. The data help in crop estimation, urban planning, water resource management, and military intelligence.[6]

The instrument suite aboard the CBERS-2B spacecraft consisted of three systems:

  • Wide Field Imager (WFI) produced visible-light to near-infrared images with a resolution of 260 meters (850 feet) and a swath width of 890 kilometers (550 miles).
  • High-resolution CCD camera was used for multispectral imaging at a resolution of 20 m (66 ft) with a swath width of 113 km (70 mi).
  • High Resolution Camera (HRC) was a panchromatic imager with a resolution of 2.5 m (8 ft 2 in) and a swath width of 27 km (17 mi).[7]

The HRC replaced the lower-resolution Infrared Multispectral Scanner instrument flown on earlier CBERS satellites.[1]

Launch

[edit]

A Long March 4B carrier rocket, operated by the China Academy of Launch Vehicle Technology (CALT), 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 Center (TLSC).[2] The satellite was successfully placed into a Sun-synchronous orbit.[8]

Last contact

[edit]

The CBERS-2B spacecraft suffered a power system failure on 10 May 2010, leaving it unable to continue operations. It remains in orbit.[3]
