The XM-4 satellite will have 18 kilowatts of total power at the beginning of life on orbit. Specified for a 15-year lifespan, Sea Launch's accurate insertion into transfer orbit should provide additional years of service life.

XM-4 broadcast satellite	Permalink

Sea Launch Company today successfully delivered the XM-4 broadcast satellite to geosynchronous transfer orbit (GTO). Early data indicate the spacecraft is accurately positioned and in excellent condition. A Zenit-3SL vehicle lifted off at 3:49 pm Pacific Standard Time (23:49 GMT) from the Odyssey Launch Platform, positioned at 154 degrees West Longitude in the equatorial Pacific. All systems performed nominally throughout the flight. The Block DM upper stage inserted the 5,193 kg (11,448 lbs.) spacecraft into geosynchronous transfer orbit, on its way to final orbital position of 115 degrees West Longitude. A ground station at Hartebeesthoek, near Pretoria, South Africa, acquired the first signal from the satellite in orbit. Read more __________________
