CBERS serial satellites
China has been collaborating with Brazil on the development of Earth resources satellites since 1988. The first China-Brazil Earth Resource Satellite (CBERS) was launched in October 1999. It is the first sun-synchronous orbit Earth resource satellite cooperatively developed by the two countries.
The third CBERS satellite, CBERS-2B, was launched in 2007. It carried CCD, HRC and WFI sensors and has spatial resolution up to 2.36m. It acquired a vast amount of observation data which has been widely used in different areas of national economic construction, such as agriculture, forestry, water resources, land resources, urban planning, environmental monitoring and disaster monitoring.
The SJ-9A satellite was launched on 14 October 2012.
SJ-9A is in orbit 645km above the Earth and collects data in a swath 30km wide. It has a spatial resolution of 2.5m (panchromatic mode) and 10m (multispectral mode). It has a field of view of ±35°off-nadir.
SJ-9A's revisit interval is 69 days. The revisit time can be shortened to 4 days by side-looking mode.
