DirecTV Satellite Fleet
The DirecTV satellite fleet is a group of communications satellites located at various geostationary orbits that DirecTV uses for their satellite television service and HughesNet (formerly known as ''DirecWAY'' and ''DirecPC'') internet service. The "DirecTV" prefix in their names has been changed to "T". Satellite table Defunct satellites are highlighted in gold. Details of satellite fleet DirecTV 1 The first of the fleet, DirecTV 1, launched on December 17, 1993, aboard an 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications Satellites
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satellites is to re ...

T11 (satellite)
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 read ...
