Apstar 7
# Apstar 7

Apstar-7 is a Chinese communications satellite which is operated by APT Satellite as part of the Apstar system. It was launched in 2012 as a replacement for the Apstar 2R satellite launched in 1997.

Apstar-7 was constructed by Thales Alenia Space, and is based on the Spacebus-4000C2 satellite bus. The satellite had a mass at launch of 5,054 kilograms (11,142 lb), and is expected to operate for at least 15 years. It is positioned in geostationary orbit at a longitude of 76.5 degrees East, and carries 56 transponders with an operating power of 8.4 kilowatts; 28 operating in the C band and providing services to Asia, Africa, eastern and central Europe and Australia and the other 28 operating in the $K_u$ band, covering Africa, the Middle East, China, and Taiwan. The satellite's solar arrays generate 11.4 kilowatts of power.

Apstar-7 was launched by a Long March 3B/E carrier rocket, flying from Launch Complex 2 at the Xichang Satellite Launch Centre. Liftoff took place at 10:27 UTC on 31 March 2012, with the rocket placing the satellite into a supersynchronous transfer orbit.

## Operational history

Thales Alenia Space built Apstar-7 as an ITAR-free satellite, containing no restricted American components. The United States prohibits the export of satellite components when a Chinese launcher will be used. Ironically, the US Department of Defense leased bandwidth on Apstar-7 in May 2012 to improve communications with the U.S. Africa Command. In 2013, Thales Alenia was forced to discontinue its ITAR-free satellite line after US supplier Aeroflex admitted that it had sold them ITAR-controlled components.
