DirecTV-12, also known as D12, is a Boeing model 702 satellite built by the Boeing Satellite Development Center. It was launched on December 29, 2009 and became operational on May 19, 2010. It is used by DirecTV to provide additional high definition channels and Video on demand content, as well as 3DTV channels and content.
D12 was launched successfully by International Launch Services on December 29, 2009 at 6:22 AM Kahzakstan time (00:22 UTC)  from the Baikonur Cosmodrome in Kazakhstan aboard an Enhanced Proton Breeze-M rocket. The launch was televised publicly live on DirecTV channel 577, on C-Band satellite, and online at ILS's website.
DirecTV-12 reached 76° W on February 11, 2010 and began testing 2 days later. After 3 weeks of scheduled testing, RB-2A began being tested. On April 23, D12 was granted a Special Temporary Authority to continue testing at 76° W for 30 more days. Testing was completed in late April.
Drift to final position
On March 31, 2010 DirecTV filed a Special Temporary Authority for permission to drift to its final position at 103° W. It was granted on April 23. It reached its final position on May 11 and began operations on May 13. Boeing handed the satellite over to DirecTV on May 17.
Broadcasting to customers
D12 increased DirecTV's national HD channel capacity to over 200 channels and expanded its availability of local channels in HD.
