*Default sort column
- A DirecTV-2 having reached the end of its useful life span, on April 16, 2007, the FCC granted DirecTV's request to conduct operations to deorbit the satellite, it was subsequently removed from service in May 2007.
- B DirecTV-3 was removed from service in Oct 2002 and sent to a storage orbit as an on-orbit backup. It returned to service in 2003 having been leased to Telesat, which used the satellite as backup for its troubled Nimiq-2 at 82 degrees West under the designation Nimiq-2i. In 2004 the satellite was moved to back up Nimiq-1 and is now operated under the name Nimiq-3.
- C DirecTV-6 went out of service August 15, 2006 and sent to a graveyard orbit having suffered damage from a solar flare in April 1997 as well as other solar array and power fluctuation problems.[10]
- D Galaxy 3C is operated by Intelsat. DirecTV leases non-DBS FSS transponders for international programming under the auspices of the DirecTV World Direct package.
[edit] Details of satellite fleet
[edit] Galaxy 3C
Galaxy 3C is a geostationary communications satellite located at 95° W. It was launched on June 15, 2002, with a Sea Launch vehicle, and is currently active on the C and Ku-bands, with 24 transponders for each. Owned by Intelsat, some of the satellite's users include DirecTV's Brazil and Latin America systems, the Racetrack TV Network DBS service, and HughesNet.
Rite-Aid, TJ Maxx, and Chevron use Galaxy 3C as a VSAT platform.
[edit] SPACEWAY 1 & SPACEWAY 2
The SPACEWAY satellites were originally designed for use by Hughes Electronics. The satellites were re-purposed for DirecTV after News Corporation purchased a controlling interest in Hughes.
[edit] DirecTV-10, DirecTV-11, and DirecTV-12
DirecTV satellites 10, 11, and 12 are Boeing model 702 satellites designed to deliver high definition television to the continental United States, Hawaii, and Alaska.
DirecTV successfully launched its newest satellite, DirecTV-12, on December 28, 2009. [7] It became fully operational on May 19, 2010.
