China–Brazil Earth Resources Satellite 2B(CBERS-2B), also known asZiyuan 1-2B,was aremote sensingsatellite operated as part of theChina–Brazil Earth Resources Satellite programbetween theChineseCenter for Resources Satellite Data and ApplicationandBrazilianNational Institute for Space Research.[1]The third CBERS satellite to fly, it was launched by China in 2007 to replaceCBERS-2.[2]
Spacecraft[edit]
CBERS-2B was a 1,450-kilogram (3,200-pound) spacecraft built by theChina Academy of Space Technologyand based on thePhoenix-Eye 1satellite 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-stabilizedspacecraft carries a low 20 m resolution, and a higher 2.5 m resolution camera. The data help incrop estimation,urban planning,water resource management,andmilitary 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]
ALong March 4Bcarrier rocket,operated by theChina 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, usingLaunch Complex 7at theTaiyuan Satellite Launch Center(TLSC).[2]The satellite was successfully placed into aSun-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]
