Intelsat 15, also known as IS-15, is a communications satellite owned by Intelsat. Intelsat 15 was built by Orbital Sciences Corporation, on a Star-2.4. It is located at 85° E longitude on the geostationary orbit. It was launched from Baikonur Cosmodrome to a geosynchronous transfer orbit on 30 November 2009 by a Zenit-3SLB launch vehicle. It has 22 active Ku band transponders, plus eight spares. Five of those transponders are owned and operated by SKY Perfect JSAT Group under the name JCSAT-85.
Intelsat 15 is a 3 axis stabilized geostationary communications satellite based on the Star-2.4 satellite bus. It weighted 2,484 kg (5,476 lb) at launch, had a dry mass of 1,227 kg (2,705 lb), and a design life 15 years. It had a power availability dedicated to the payload of 4.6 kW, thanks to its Multi-junction GaAs solar cells. It also had two 4840 watt hour Li-ion batteries for surviving the solar eclipses.
The satellite used a bipropellant propulsion system with a IHI BT-4 Liquid Apogee Engine for orbit circularization and thrusters and reaction wheels for station keeping and attitude control. It was filled with enough propellant for 15 years, but due to the efficient launch and transfer 17 are expected.
