The operation of CBERS satellites is shared between Brazil and China according to a handover schedule.

Cachoeira Paulista, The information compiled and edited in this article was provided by Herbert J. Kramer from his documentation of: ”Observation of the Earth and Its Environment: Survey of Missions and Sensors” (Springer Verlag) as well as many other sources after the publication of the 4th edition in 2002. The satellite ZY-1 FM1 (Zi Yuan-1 Flight Model 1) of this 1st generation program came to be known as CBERS-1. WFI is also a complementary sensor to HRCC. The internal environment of the satellite is being kept by an active and passive thermal control system. 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. The spacecraft carries the identical payload as flown on CBERS-1 and -2 (see description under CBERS-1). The HRCC raw images in each band are composed by five parts (three arrays and two overlap regions) as presented in Figure 10. 16-19, 2) “The China-Brazil Earth Resources Satellite Program,” paper provided by G.

Hubscher, “CBERS - An International Space Cooperation Program,” Acta Astronautica, Vol. The HRCC instrument is steerable up to ±32º about nadir in the cross-track direction to obtain stereoscopic imagery. A complete coverage cycle of the panchromatic camera takes 26 days. The S-band is used for TT&C services. CBERS-2B has a total mass of 1450 kg, with bus dimensions of 1.78 m x 1.980 m x 2.14 m. The satellite has three axis stabilization. The spacecraft carries the identical payload as flown on CBERS-1 (see description under CBERS-1).

CBERS-2 satellite image of South America. - Since March 2010, Brazilian and Chinese technicians had been trying to restore nominal operations of CBERS-2B. CBERS-4 Infrared Medium Resolution Scanner Imagery, Brazil' National Institute for Space Research (INPE), Toggle Archive And Distribution Information. These images are (by default) sent via FTP to the users for downloading. The receiving stations of the CBERS imagery are located in: Beijing, Nanning, and Wulumuqi. SP The telescope has an aperture diameter of 250 mm and a focal length of 1 m for the Pan and SWIR bands, and 0.5 m for the TIR (Thermal Infrared) band. The linear scan mirror performs cross-track scanning at a scan rate of 5.39 Hz and a scan angle of ±2.5º. Cachoeira Paulista, CDCBERS reads CBERS TIFF file format data when satellite orthorectification is required. CBERS-2 was integrated and tested in the Integration and Test Laboratory of INPE. Objective: detection of high-energy radiation. Infrared Medium Resolution Scanner. The DCS retransmits these messages in UHF and S bands to Earth. They are unique systems due to the use of on board cameras which combine features that are specially designed to resolve the broad range of space and time scales involved in our ecosystem.
