Eutelsat 113 West A, formerly Satmex-6, is a geostationary communications satellite which is operated by Eutelsat. Originally built for Mexico's Satmex, it was launched in 2006. The satellite was acquired by Eutelsat in its 2014 merger with Satmex, and renamed Eutelsat 113 West A in May.[2] It is used to provide communications services to the Americas, Hawaii and the Caribbean.[3]

Constructed by Space Systems/Loral, Satmex 6 is based on the LS-1300X satellite bus. It is equipped with 36 G/H band (IEEE C band) and 24 J band (IEEE Ku-band) transponders, and at launch it had a mass of 5,456 kilograms (12,028 lb), with an expected operational lifespan of 15 years.[2][4]

Arianespace was contracted to launch Satmex 6, using an Ariane 5ECA carrier rocket flying from ELA-3 at the Guiana Space Centre. The launch occurred at 21:09 GMT on 27 May 2006, and placed Satmex 6, along with the Thaicom 5 satellite, into a geosynchronous transfer orbit.[5] At the time, this was the heaviest dual-satellite payload ever launched to geostationary transfer orbit.[6]

Following launch, the satellite raised its own orbit by means of an onboard apogee motor. At 18:33 GMT on 31 May, it was injected into geostationary orbit. It was subsequently tested, and positioned at a longitude of 113° West for operational service.[7]
