Intelsat 15
[6][7] It had a power availability dedicated to the payload of 4.6 kW, due to its multi-junction GaAs solar cells.[6] The satellite used a bipropellant propulsion system with an IHI BT-4 Liquid Apogee Engine for orbit circularization and thrusters and reaction wheels for station keeping and attitude control.The satellite, also known as IS-15, would provide services to the Asia-Pacific, Indian Ocean and Middle East regions from the 85°E longitude on the geostationary orbit, where it would replace Intelsat 709.It would be based on the STAR-2 satellite bus, generate 4.6 kW of power for its 22-transponder Ku band payload and had an expected launch date of early 2009.The contract was itself a renegotiation for repurpose two already existing reservation by Intelsat with Sea Launch for two satellites to these new spacecraft.
