CBERS-2 Satellite Sensor

The CBERS-2 identical to CBERS-1 Program was born from a partnership between Brazil and China in the space technical scientific segment. CBERS-1 was launched successfully on October 21, 2003 from the Taiyuan Satellite Launch Center in China. The launch time was 11:16AM (Beijing local time), which corresponds to 1:16AM (Brasilia local time). Satellite images from CBERS-2 are used in important areas, as deforestation and fire control in the Amazon Region, water resources monitoring, urban growth, soil occupation, education and several other applications. One important application is the hydrological basin monitoring by the ANA and SIVAM platform networks, which provides Brazilian river and rain data.

The CBERS satellite is composed of two modules. The payload module houses the optical system (CCD - High Resolution CCD Cameras, IRMSS - Infra-Red Multispectral Scanner e WFI - Wide Field Imager) and the electronic system used for Earth observation and data collecting with a resolution capability ranging from 20 meters to 260 meters. The service module incorporates the equipment that ensures the power supply, control, telecommunications and all other functions needed for the satellite operation.
