Details of satellite fleet

DirecTV 1

The first of the fleet, DirecTV 1, launched on December 17, 1993 aboard a Ariane 4 launch vehicle. DirecTV 1 commenced operations on June 17, 1994, positioned at 101.2° W. The satellite experienced a satellite control processor failure in July 1998, but the satellite was able to continue operating on its backup SCP for the rest of its operational life. In 1999, the satellite was relocated to 110° W. In June 2003, the satellite was relocated back to 101.2° W, as the satellite was incapable of providing service to Hawaii. In July 2005, the satellite was relocated to 72.5° W, as the former satellite at that position (DirecTV 5) had moved to 110° W to replace DirecTV 6, which was approaching the end of its fuel life. In 2007, the satellite was relocated to 91.1° W, and leased to Telesat. Having reached the end of its useful lifespan, DirecTV 1 was de-orbited on February 20, 2009.

DirectTV 2

DirecTV 2 was launched on August 3, 1994 aboard a Atlas 2-A rocket from Cape Canaveral. This spacecraft is special in that it carries a time capsule named SpaceArc, with the intention of moving the spacecraft into an higher orbit at the end of its life so that a explorer would be able to uncover the messages in the distant future. Among the items contained in SpaceArc are messages from then Vice President Al Gore and his predecessor Dan Quayle. In January 2006, the satellite was relocated to 91.1° W, in order to support Telesat's BSS service in Canada. DirecTV 2 reached the end of its operational life on May 20, 2007, when it was successfully de-orbited.

DirecTV 3/Nimiq 3

DirecTV 3 was launched on June 10, 1995 aboard a Ariane 42-P launch rocket, serving as an in-orbit backup. In 2002, the satellite's main spacecraft control processor failed, prompting DirecTV to move the spacecraft into a storage orbit. The satellite was recalled in October 2003 and leased to Telesat, relocating to 82° W in order to provide backup for Nimiq 2. In 2004, the satellite was relocated to 91° W, backing up Nimiq 1. The satellite reached the end of its life and was subsequently de-orbited in May 2009.

DirecTV-1R

DirecTV-1R was launched on October 9, 1999 aboard a Sea Launch Zenit-3SL launch vehicle. It was the first satellite used to broadcast local channels for DirecTV in major DMAs, and was positioned at 101.2° W when it first entered service. In April 2007, the satellite was relocated to 72.5° W and leased to Telesat to cover the loss of DirecTV 2 and serve as backup capacity to the troubled Nimiq 2 satellite. In early 2012, DirecTV-1R was briefly repositioned to 109.8° W as a spare for DirecTV-5, however, in mid-2012, it was announced that DirecTV-1R would be leased to the Russian Satellite Communications Company, and was repositioned to its current location at 55.8° E in late 2012 as a stopgap supplement to the RSCC's aging Bonum 1 satellite due to delays of the RSCC's Express-AT1 satellite. Express-AT1 was launched on March 15, 2014 and DirecTV 1R was de-orbited on May 22, 2014.

T4S

T4S (formerly DirecTV-4S) was successfully launched on November 27, 2001 aboard a Ariane 44LP rocket from the Guiana Space Center on the northeastern coast of South America. T4S was a 9,400-pound, 86-foot-long, and 24.5-foot-wide high powered satellite. T4S was the first satellite for DirecTV to employs spot beams. This technology reuses the same frequencies on multiple spot beams to reach the major television markets where DirecTV delivers the signals of local network affiliates. The satellite carried two Ku-band payloads: spot beams for local channels, and a national beam payload. The spot beam payload used a total of 38 traveling wave-tube amplifiers (TWTAs) ranging in power from 30 to 88 watts. The national beam payload carried two active transponders with further capability for two active high-power transponders and six active low-power transponders. The satellite was stationed at 101° W for its entire operational life. In September 2019, T4S reached the end of its operational life and was subsequently de-orbited.

T5

T5 (formerly DirecTV 5) was successfully launched on May 7, 2002 aboard a Proton rocket from the Baikonur Cosmodrome in Kazakhstan. Originally built for PrimeStar, DirecTV acquired the satellite in its 1999 buyout of the company. The satellite was relocated from 119° W to 72.5° W in 2004 and temporarily leased to Telesat for their Canadian BSS service. In July 2005, the satellite replaced DirecTV 6 at 110° W, where it has remained ever since.

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 s, 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. DirecTV is currently slowly discontinuing use of this satellite, with international channels moving to T12 and T14.

Rite-Aid, TJ Maxx, and Chevron use Galaxy 3C as a VSAT platform.

T7S

T7S (formerly DirecTV 7S) was successfully launched on May 4, 2004 aboard a Sea Launch Zenit-3SL launch vehicle. The satellite, located at 119° W, is the second of the fleet to employ spot beams, with a main focus on providing high capacity for local channels. The satellite is scheduled to be de-orbited starting January 11, 2021.

Spaceway 1 and Spaceway 2

The SPACEWAY satellites were originally designed for use by Hughes Electronics to provide both TV and broadband internet service. The satellites were re-purposed for DirecTV after News Corporation purchased a controlling interest in Hughes. Though Spaceway 1 was damaged and subsequently shut down in February 2020, Spaceway 2 continues to operate as a backup satellite.

T8

T8 (formerly DirecTV 8) was successfully launched on May 22, 2005 aboard a Proton M launch vehicle from the Baikonur Cosmodrome in Kazakhstan. The first Ku/Ka hybrid satellite in the fleet, T8 employs 16 transponders. In 2020, T8 was relocated to 119° W, replacing T7S.

T9S

T9S (formerly DirecTV 9S) was successfully launched on October 13, 2006 aboard a Ariane 5 launch vehicle. T9S is fitted with 52 Ku-band transponders and 2 Ka-band transponders, making for a total of 54 high-power transponders. The satellite is located at 101.1° W.

T10

T10 (formerly DirecTV 10) was successfully launched on July 6, 2007 aboard a Proton M launch vehicle from the Baikonur Cosmodrome in Kazakhstan. T10 is employed with 55 spot-beam Ka-band transponders and 32 broad-beam transponders, making up for a total of 87 high-power transponders. T10's launch marked the beginning of mass HDTV expansion for DirecTV, as its transponders employed MPEG-4 technology. Shortly after launch, T10 suffered a anomaly that limited the satellite's capacity, prompting DirecTV to temporarily transfer all commercial service from T10 to T11 while the company worked on fixing the issue. During the process, T10 was relocated slightly from 102.8° W to 102.6° W. The fixes were eventually completed and T10 was drifted back to 102.8° W, where it currently remains.

T11

T11 (formerly DirecTV 11) was successfully launched on March 19, 2008 aboard a Sea Launch Zenit-3SL launch vehicle. The satellite is functionally identical to T10 and is located at 99.2° W.

T12

T12 (formerly DirecTV 12) was successfully launched on December 28, 2009 aboard a Proton M launch vehicle from the Baikonur Cosmodrome in Kazakhstan. After a period of testing, T12 commenced operations on May 17, 2010. T12's payload consists of 32 active and 12 spare Ka-band traveling-wave tube amplifiers and 55 active and 15 spare spot beam TWTAs. T12 is located at 102.75 W as of October 2020.

T14

T14 (formerly DirecTV 14) was successfully launched on December 6, 2014 aboard a Ariane 5 launch vehicle from the Guiana Space Center in South America.
