China-Brazil Earth Resources Satellite program

In 1999, the first China-Brazil earth resource satellite was successfully launched, giving each country its first transmission-type remote sensing satellite. China-Brazil Earth Resources Satellite 04A, the sixth satellite jointly built by China and Brazil, was launched in 2019.

The program set a good example for cooperation among developing countries in the field of space technology, and was praised as a model of "South-South cooperation". Data from the satellites are provided to developing nations for free.
