ChinaSat 12 was also known as Apstar 7B (as a backup of Apstar 7), but acquired by China Satellite Communications from its subsidiary APT Satellite Holdings in 2010.[9] However, APT Satellite Holdings was contracted by its parent company as the operator of ChinaSat 12.[9]

Orbit

Following launch on 27 November 2012,[10] the satellite was placed into geosynchronous orbit and located at 51.5° East while being tested. On April 19, 2013, it started to move towards its operational location at 87.5° East.

The satellite was built by Thales Alenia Space and has a designed life of 15 years.

gollark: It says it's already claimed anyway.
gollark: Waiting for things does not really keep you busy.
gollark: But you don't know when the sponsored bit *ends*.
gollark: The conversion rate on random adverts on YouTube can't be that high, and there are obvious diminishing returns, and they are not on the whole hugely costly services.
