DirecTV-11
T11, formerly known as DirecTV-11, is a Boeing model 702 satellite built by the Boeing Satellite Development Center. Its current name was adopted in 2017. Technology This satellite is functionally identical to T10 and is co-located with SPACEWAY-2 at or very near 99.225°W. Launch data T11 had originally been scheduled for launch by Sea Launch in November, 2007. Following a launch failure at Sea Launch that resulted in damage to the facility, the expected launch date was changed to March 19, 2008. Launch occurred at 22:47:59 UTC on March 19, 2008, and the spacecraft separated from the carrier rocket 61 minutes later, following a successful ascent. Testing Boeing handed over the T11 satellite to DirecTV on Monday, July 21, 2008, according to a press release on the Boeing website. This means that the satellite is "parked" at or extremely close to its final location of 99.225ºW. Customers with High-Definition receivers or High-Definition DVRs can see new satellite reading ...

It covers satellites massing from to with power outputs from 3 to 18 kW and can carry up to approximately 100 high-power transponders. The baseline Boeing 702 is compatible with several orbital launch systems, including Atlas V, Ariane 5, Delta IV, Falcon 9, Proton, and the Sea Launch-operated Zenit 3SL. Platform versions After the introduction of the original 702 in 1997, the platform has been continually updated. New members of the platform have been introduced through the years, which allowed the common systems and approaches to span the whole range of mass and power for geosynchronous orbit satellites. The family currently spans four different members: the 702HP for high-power applications, the 702HP-GEO for mobile-telephone services, the 702MP for medium-power requirements and the 702SP for small satelli ...

Sea Launch
Sea Launch was a multinational—Norway, Russia, Ukraine, United States—spacecraft launch company founded in 1995 that provided orbital launch services from 1999–2014. The company used a mobile maritime launch platform for equatorial launches of commercial payloads on specialized Zenit-3SL rockets from a former mobile/floating oil drilling rig renamed ''Odyssey''. By 2014, it had assembled and launched thirty-two rockets, with an additional three failures and one partial failure. All commercial payloads were communications satellites intended for geostationary transfer orbit with such customers as EchoStar, DirecTV, XM Satellite Radio, PanAmSat, and Thuraya. The approach Sea Launch LLC used was to assemble the launcher on a purpose-built ship ''Sea Launch Commander'' in Nimitz Rd., Long Beach, California, USA. The assembled spacecraft was then positioned on top of the self-propelled ''Odyssey'' floating launch platform and moved to the equatorial Pacific Ocean for launc ...

Geocentric Orbit
A geocentric orbit or Earth orbit involves any object orbiting Earth, such as the Moon or artificial satellites. In 1997, NASA estimated there were approximately 2,465 artificial satellite payloads orbiting Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center. More than 16,291 objects previously launched have undergone orbital decay and entered Earth's atmosphere. A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. For a low Earth orbit, this velocity is about ; by contrast, the fastest crewed airplane speed ever achieved (excluding speeds achieved by deorbiting spacecraft) was in 1967 by the North American X-15. The energy required to reach Earth orbital velocity at an altitude of is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude.

Geostationary Orbit
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular geosynchronous orbit in altitude above Earth's equator ( in radius from Earth's center) and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas do not have to rotate to track them but can be pointed permanently at the position in the sky where the sat ...

Zenit-3SL
The Zenit-3SL is an expendable carrier rocket operated by Sea Launch. First flown in 1999, it has been launched 36 times, with three failures and one partial failure. It is a member of the Zenit family of rockets, and is built by the Yuzhnoye Design Bureau. RKK Energia produces the Block DM-SL upper stage, whilst the payload fairing is produced by Boeing. Launches are conducted from the Ocean Odyssey platform anchored on the equator in the Pacific Ocean, at a point with 154°W longitude, about 370 kilometres east of Kiritimati. The Zenit-3SL design began in the late 1980s as the Zenit-3, a proposed replacement for the Proton-K, which would have used a Zenit-2 rocket with a Block D upper stage. This proposal was shelved after the dissolution of the Soviet Union, as Russia inherited the space programme, however the Zenit was manufactured in Ukrainian SSR. Boeing became involved in the programme in 1994. The design was subsequently modified, with a modified version of the Block DM r ...

Boeing Satellite Development Center
The Boeing Satellite Development Center is a major business unit of Boeing Defense, Space & Security. It brought together Boeing satellite operations with that of GM Hughes Electronics' Space and Communications division in El Segundo, California. History The facility was originally built by Nash Motors in 1946 and begun production in 1948, building the Nash Rambler. Howard Hughes' Hughes Aircraft Company formed the Aerospace Group within the company when they bought the facility in 1955, when the Nash company became American Motors Corporation and divided the facility into: * Hughes Space and Communications Group * Hughes Space Systems Division In 1953, the Howard Hughes Medical Institute (HHMI) was formed, and Hughes Aircraft reformed as a subsidiary of the foundation. The charity status of the foundation allowed Hughes Aircraft to avoid taxes on its huge income. In 1961, the two Aerospace Group divisions were reformed as Hughes Space and Communications Company.
