CBERS-2

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 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 1,450-kilogram (3,200 lb) 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 (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 Infrared Multispectral Scanner (IMS), had a resolution of 80 metres (260 ft) and a swath width of 120 kilometres (75 mi).

CBERS-3

China–Brazil Earth Resources Satellite 3 (CBERS-3), also known as Ziyuan I-03 or Ziyuan 1D, was a remote sensing satellite intended for operation 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 fourth CBERS satellite to fly, it was lost in a launch failure in December 2013.

Spacecraft

CBERS-3 was a 1,980-kilogram (4,370 lb) spacecraft based on the Phoenix-Eye 1 satellite bus. It was developed by the China Academy of Space Technology, in partnership with Brazil, at a cost of US$125 million for each party. The spacecraft had a single solar array which would have provided power to its systems, generating 2,300 watts of electrical power, and had a design life of three years.

The CBERS-3 spacecraft carried four instruments: MUXCam, a multispectral camera; PanMUX, a panchromatic imager; the Infrared Medium Resolution Scanner, or IRSCAM, and WFICAM, a wide-field imaging camera. These cameras were to have been used to observe a swath of 120 kilometres (75 mi) of landmass at a time, enabling the satellite to scan the entire surface of the planet every 26 days, with a spatial resolution of up to 20 metres (66 ft).

CBERS-4

China–Brazil Earth Resources Satellite 4 (CBERS-4), also known as Ziyuan I-04 or Ziyuan 1E, is a remote sensing satellite intended for operation 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 fifth CBERS satellite to fly, it was successfully launched on 7 December 2014. It replaces CBERS-3 which was lost in a launch failure in December 2013.

CBERS-1

China–Brazil Earth Resources Satellite 1 (CBERS-1), also known as Ziyuan I-01 or Ziyuan 1A, is a remote sensing satellite which was operated as part of the China–Brazil Earth Resources Satellite programme between the China National Space Administration and Brazil's National Institute for Space Research. The first CBERS satellite to fly, it was launched by China in 1999.
