On April 24, 2015, China and Brazil have signed the agreement for the construction of CBERS-4A. It's a third satellite in the continuity to the CBERS program, and a sixth CBERS satellite to be constructed. The CBERS satellites enhance and complement the existing remote sensing systems in an effort to improve our knowledge about the Earth environment and resources.
OBJECT B was lifted into orbit during the mission ‘Long March 4B | CBERS-4A’, on board a Long March 4B space rocket.
The launch took place on Dec. 20, 2019, 3:22 a.m. from Launch Complex 9.
