The satellite has three axis stabilization. Telescope focal length=520 mm (all refracting lens system); aperture=f/4; spatial resolution = 19.5 m (at nadir); IFOV=25 µrad; FOV= 8.4º; temporal resolution=26 days (nadir view), off-nadir view (pointable side-looking capability of ±32º, providing an increased observation frequency for a given region - any phenomenon or event detected by WFI may be zoomed by HRCC ) minimum time lag of 3 days; swath width = 113 km; objective: high resolution imaging.
• In addition to the imaging payload, the satellite carries a Data Collection System (DCS) and Space Environment Monitor (SEM). The satellite ZY-1 FM1 (Zi Yuan-1 Flight Model 1) of this 1st generation program came to be known as CBERS-1. IRMSS was developed and built by the Beijing Institute of Space Machines and Electricity and sponsored by CAST. 10). Spectral bands: 0.63-0.69 µm, 0.77-0.89 µm; spatial resolution = 260 m (3456 pixels per line); temporal resolution = 3-5 days; swath width = 890 km (FOV = 60º); data quantization = 8 bit; data rate = 1.1 Mbit/s; objective: acquisition of low-resolution wide-swath imaging (WFI provides a synoptic view). There is no archive and distribution information for this collection. 16-19, 2) “The China-Brazil Earth Resources Satellite Program,” paper provided by G.

Hubscher, “CBERS - An International Space Cooperation Program,” Acta Astronautica, Vol. Cachoeira Paulista, The CBERS-2B satellite is designed for global coverage and include cameras that make optical observations and a Data Collection System transponder to gather data on the environment. Orbit: The orbital characteristics are identical to those of CBERS-1, i.e., sun-synchronous circular orbit; altitude = 778 km; inclination = 98.5º; nodal period = 100.26 minutes; mean local solar time on descending node at 10:30 AM; revisit period of 26 days. Figure 13: CBERS ground stations for Africa (image credit: CRESDA, INPE) Background: Already in the summer of 2004, Brazil and China (INPE, CRESDA) changed the data policy for the CBERS Program including provisions for reception, processing and dissemination of CBERS imagery to countries other than Brazil and China.
The Brazilian Data Catalog is open to the public for HRCC and WFI data.
This camera is built under China responsibility and it is an upgrade of the Infrared Multispectral Scanner (IRMSS) of the CBERS-1 and 2 satellites. In Brazil, the SCC is located in São José dos Campos (at INPE), and by the ground stations are: Cuiabá and Alcântara. The radiation from the prime focal mirror is divided into three parts by relay optics. The swath width is 866 km, the spatial resolution is 64 m on nadir and the image data bit rate is 50 Mbit/s. The spacecraft was jointly developed by INPE and CAST. • HRCC operations were interrupted in May 2006 due to a power supply anomaly. 22). 15), 0.42-0.52 µm
