Eutelsat 12 West B, known as Atlantic Bird 2 prior to 2012 and Eutelsat 8 West A from 2012 to 2015, was a geostationary communications satellite. Operated by Eutelsat, it provides direct-to-home (DTH) broadcasting services from geostationary orbit. The satellite is part of Eutelsat constellation at a longitude of 8° West, then 12.5° West. Eutelsat announced the order of a new Spacebus-3000B2 satellite bus from Alcatel Space in October 2012.

Satellite description

Atlantic Bird 2 was a 3,150 kg (6,940 lb) satellite with a design life of 12 years. It is equipped with an S400-12 apogee motor which was used for initial orbit-raising manoeuvres and an S10-18 engine for station keeping burns.[1] The spacecraft has 26 Ku-band transponders.[2]

Launch

Atlantic Bird 2 was launched on the Ariane 44P launch vehiclen from Centre Spatial Guyanais at the Kourou in French Guiana. Liftoff occurred at 23:21 UTC on 21 September 2001,[3] with the launch vehicle successfully injecting its payload into geosynchronous transfer orbit (GTO). The launch was conducted by Arianespace.

Mission

Following launch, the satellite Atlantic Bird 2 used its apogee motor to raise itself into geostationary orbit, positioning itself at a longitude of 8° West. In December 2011, Eutelsat announced, that their satellite assets will be renamed under a unified brand name effective from March 2012. This satellite became Eutelsat 8 West A at 8° West. In 2015, it was moved to 12.5° West and named Eutelsat 12 West B. It has been moved to a graveyard orbit in October 2020.[2]
