T12 , formerly 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. The satellite adopted its current name in 2017.

38-493: A B-Band Converter (BBC). DirecTV supplies BBCs with all 5-LNB K u /K a -band dish systems. The satellite signal from T10 is downconverted at the dish to the frequency range of 250-750 MHz, called "K a -lo". At the receiver when necessary, the BBC in response to a control signal from the receiver blocks any original "K a -hi" signals between 1650-2150 MHz. Then up-converts the 250-750 MHz signals to this range which

76-456: A broadband 2-way internet service. At the request of DirecTV, Boeing disabled the on-board processing payload designed to deliver enhanced connectivity for the 2-way internet service. T10 and T11 use this 500 MHz of spectrum for yet more simple one-way broadcast HDTV. Since the 500 MHz frequency block (18.3-18.8 GHz) used by T10 and T11 on downlink were not intended for DBS broadcasting, existing equipment cannot receive them without
95-515: A post launch anomaly that has limited the capacity available in certain local markets. DirecTV believes that it can ameliorate this condition, but will need to discontinue commercial service from the satellite and relocate it slightly so that it is not within the cluster of its other operational satellites. Accordingly, DirecTV intends to move DirecTV 10 to the 102.6° position to conduct the restorative procedure. During this migration, DirecTV 10 will continue to provide service to subscribers.

133-691: Is different from Wikidata All article disambiguation pages All disambiguation pages T12 (satellite) This satellite is similar to T10 and T11 , but features a 17/24 GHz BSS payload carrying the moniker RB-2A. It is co-located with T10 very near 103.0°W. On November 27, the satellite was shipped to the Baikonur Cosmodrome in the Kazakhstan desert from the Boeing facility in El Segundo, California . T12
152-439: Is expected by current receivers. Because this frequency range conflicts with terrestrial broadcast frequencies, any off-the-air (OTA) diplexors must be placed at some point after the BBC. T10 uses 32 active and 12 spare K a -band Traveling wave tube amplifiers (TWTA) to broadcast national programming and 55 active and 15 spare spot beam TWTAs for local television services. The satellite uses bent pipe communications. It
171-487: Is powered by a solar array spanning 48.1 meters that consists of ultra triple junction gallium arsenide solar cells. DirecTV reported in a press release on September 14, 2007 that in-orbit testing had uncovered problems with the satellite's spot beam transponders used to broadcast local HDTV channels: While testing of DIRECTV 10's capability continues, it appears that a portion of the anticipated spot-beam capability may not be fully available. The investigation to determine
190-402: The Baikonur Cosmodrome in Kazakhstan aboard an Enhanced Proton Breeze-M rocket. After about two months of in-orbit testing, the satellite was moved to its operating position at 103.0° west longitude. This was the third DirecTV satellite launched on a Proton rocket. Prior launches include T8, which was launched on May 22, 2005, and T5, which was launched on May 7, 2002. The satellite
209-558: The H21 or HR21, and a 5-LNB K u /K a dish, such as the AT-9 "Sidecar". These receivers also receive MPEG-2 channels and offer interactive services. T10 was co-located with the SPACEWAY-1 satellite until the latter was decommissioned in 2020. The SPACEWAY satellites were originally designed so that 500 MHz of spectrum would be used for simple one-way broadcasting and 500 MHz for

247-486: The T-suffix. T10 transmits MPEG-4 encoded signals, a compression standard which is more efficient than MPEG-2 which DirecTV uses for standard definition and a small number of HD channels. The use of MPEG-4 compression allows the satellite to carry significantly more channels than it could using MPEG-2 compression. Receiving signals from DirecTV-10 requires an advanced receiver capable of decoding MPEG-4 signals, such as
266-470: The cause of the reduced capability and potential means to mitigate its effect is on-going. However, we currently believe our planned expansion of HD local programming as previously announced will not be materially affected. According to a May 7, 2010 FCC filing: "DirecTV 10 is currently operating at the 102.815° orbital location. As DirecTV has previously informed the Commission, that satellite suffered
285-517: The fall of 2010, the winter of 2010-11, and the spring and summer of 2011; and more in 2012. The 3DTV channels were removed by 2014 due to consumer disinterest in the format. T10 (satellite) T10 (formerly DirecTV-10) is a Boeing model 702 direct broadcast satellite that provides high-definition television (HDTV) to DirecTV subscribers in North America . It was launched by International Launch Services on July 7, 2007 from
304-432: The new satellite to add more HD channels, expand its pay-per-view movie service "DirecTV Cinema" and on demand titles. It also carried 3DTV channels. DirecTV began adding new HD channels on May 19 and continued June 23 and later in the summer. DirecTV added the first 3D channel to T12, ESPN 3D , on June 11, and new channels n3D and a pay-per-view 3D movie channel on July 1. A few more HD channels were added onto it in
323-605: Was granted a Special Temporary Authority to continue testing at 76° W for 30 more days. Testing was completed in late April. 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. T12 increased DirecTV's national HD channel capacity to over 200 channels and expanded its availability of local channels in HD. DirecTV has used
342-484: 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. T12 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, T12
361-403: Was renamed to T10 in 2017. DirecTV contracted with Boeing in 2004 to build three identical 702 model satellites — DirecTV-10, 11 and 12 . DirecTV-11 was launched on March 19, 2008 and DirecTV-12 was launched on December 29, 2009. The satellites were purchased to significantly increase the number of national and local HDTV channels DirecTV offers. All satellites have since been renamed to
