CBERS-1
China–Brazil Earth Resources Satellite 1, also known as Ziyuan I-01 or Ziyuan 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. The first CBERS satellite to fly, it was launched by China in 1999.
CBERS-1 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, providing 1,100 watts of electricity for the satellite's systems. The instrument suite aboard the CBERS-1 spacecraft consisted of three systems: the Wide Field Imager produced visible-light to near-infrared images with a resolution of and a swath width of ; a high-resolution CCD camera was used for multispectral imaging at a resolution of with a swath width of ; the third instrument, the Infrared Multispectral Scanner, had a resolution of and a swath width of.
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 Taiyuan [Launch Complex 7|Launch Complex 7] at the Taiyuan [Satellite Launch Center|Taiyuan Satellite Launch Centre]. The satellite was successfully placed into a Sun-synchronous orbit.
CBERS-1 was decommissioned in September 2003, almost four years after launch. The derelict satellite remains in orbit; as of 30 November 2013 it is in an orbit with a perigee of, an apogee of, 98.34 degrees inclination and a period of 100.35 minutes. The orbit has a semimajor axis of, and eccentricity of 0.0004025.
