Spacecraft
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 1100 watts of electricity for the satellite's systems. 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.The instrument suite aboard the CBERS-2B spacecraft consisted of three systems:
- Wide Field Imager produced visible-light to near-infrared images with a resolution of and a swath width of.
- High-resolution CCD camera was used for multispectral imaging at a resolution of with a swath width of.
- High Resolution Camera was a panchromatic imager with a resolution of and a swath width of.
