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 program between the Chinese Center for Resources Satellite Data and Application and Brazilian National Institute for Space Research . [1] The second CBERS satellite to fly, it was launched by China in 2003 to replace CBERS-1 . [3]
CBERS-2 was a 1,450 kg (3,200 lb) 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 1,100 watts of electricity for the satellite's systems. [2] [5] 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 m (850 ft) and a swath width of 890 km (550 mi) ; a 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) ; the third instrument, the Infrared Multispectral Scanner (IMS), had a resolution of 80 metres (260 ft) and a swath width of 120 km (75 mi) . [6]
A Chang Zheng 4B carrier rocket, operated by the China Academy of Launch Vehicle Technology , was used to launch CBERS-2. The launch took place at 03:16 UTC on 21 October 2003, using Launch Complex 7 at the Taiyuan Satellite Launch Center . [3] The satellite was successfully placed into a sun-synchronous orbit . [7]
Following the launch of CBERS-2B in 2007, CBERS-2 was retired from service. [2] As of 1 December 2013, the dericict satellite remains in orbit, with a perigee of 780 km (480 mi) , an apogee of 782 km (486 mi) , 98.17 degrees inclination and a period of 100.33 minutes. Its orbit has a semimajor axis of 7,152.64 km (4,444.44 mi) , and eccentricity of 0.0001886. [4]
