Apstar VI is a communications satellite built by Alcatel Space, a subsidiary of Alcatel, and was boosted into orbit on April 12, 2005 by Long March 3B launcher from Xichang Satellite Launch Center in China. It provides APT Satellite Holdings Limited (APT), a satellite operator in the Asia Pacific region, with broadband media and television services. It is fitted with 38 C-band transponders and 12 Ku band transponders. China is covered with a dedicated high power Ku band beam for broadband multimedia transmission. It is the second model of the Spacebus 4000. The transponders have a reduced C-band receiving dish over a wide footprint, which extends across India, China and Australia.

It is significant in enhancing cooperation between Alcatel Space and China as a follow up to the SINOSAT satellite.
