CBERS - China-Brazil Earth Resources Satellite ou Satélite Sino-Brasileiro de Recursos Terrestres


CBERS program (China-Brazil Earth Resources Satellite Program) was established in 1988 after a partnership between the National Institute for Space Research (INPE) and the Chinese Academy of Space Technology (CAST), a binational technical scientific agreement involving Brazil and China. 


The CBERS mission launched four satellites for earth observation: the CBERS-1 (launched in 1999 and inactive since 2003), the CBERS-2 (launched in 2003 and inactive since January 15, 2009, during which produced 175,000 images) CBERS-2B (launched in 2007 and active until early 2010), CBERS-3 (launched in 2013 and lost in the launch because of launch vehicle failures) and CBERS-4 launched in December 2014. Initially, the program provided the development and construction of only two remote sensing satellites and due to the success of the mission, in 2002 an agreement was signed for continuation of the program, which already provides for the launch of a satellite: CBERS-4. In CBERS-4A manufacturing will be used spare parts of satellites CBERS-3 and CBERS-4, in addition to various technologies applied in the development of these satellites. CBERS satellites are part of the Brazilian System of Environmental Data Collection. The CBERS-2 satellite was the first remote sensing satellite in the world to adopt the free distribution policy of images, which made the distribution policy of Brazil to be a great example of the world, which helps to spread the use of images satellites around the world.
