China–Brazil Earth Resources Satellite 1 (CBERS-1), also known as Ziyuan I-01 or Ziyuan 1A (ZY 1,[6] ZY 1A), is a remote sensing satellite which was operated as part of the China–Brazil Earth Resources Satellite program between the China National Space Administration and Brazil's National Institute for Space Research.[1] The first CBERS satellite to fly, it was launched by China in 1999.[3]
CBERS-1 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, providing 1,100 watts of electricity for the satellite's systems.[2][7] The instrument suite aboard the CBERS-1 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 km (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 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 kilometres (75 mi).[8]
A Chang Zheng 4B carrier rocket, operated by the China Academy of Launch Vehicle Technology, was used to launch CBERS-1. The launch took place at 03:15 UTC on 14 October 1999, using Launch Complex 7 at the Taiyuan Satellite Launch Centre.[3] The satellite was successfully placed into a Sun-synchronous orbit.
CBERS-1 was decommissioned in September 2003, almost four years after launch.[4] The derelict satellite remains in orbit; as of 30 November 2013 it is in an orbit with a perigee of 779 km (484 mi), an apogee of 785 km (488 mi), 98.34 degrees inclination and a period of 100.35 minutes. The orbit has a semimajor axis of 7,153.45 km (4,444.95 mi), and eccentricity of 0.0004025.[5]
