Flight V125.
Galaxy 11 is an American geostationary communications satellite that is operated by Intelsat. It is located in geostationary orbit at a longitude of 32.8 degrees east, where it serves as a backup to the Intelsat 802 spacecraft. It was originally operated at 99° West and later spent most of its operational life at 91° West, from where it was used to provide communications services to Brazil and North America. Galaxy 11 was built for PanAmSat by Hughes Space and Communications and is based on the HS-702 satellite bus. It was the first HS-702 to be launched, and the first satellite to be equipped with a XIPS propulsion system. It carries 24 G/H band and 40 J band (IEEE C and Ku bands respectively) transponders, and at launch, it had a mass of 4,477 kilograms (9,870 lb), with an expected operational lifespan of around 15 years.
