Sea Launch Successfully Delivers the XM-4 Satellite to Orbit
LONG BEACH, Calif., Oct 30, 2006 /PRNewswire via COMTEX/ --

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.

Built by the Boeing Satellite Development Center, the Boeing 702 spacecraft carries a high-power S-band Digital Audio Radio Service (DARS) payload provided by Alcatel Alenia Space. Like the three XM satellites currently in orbit, XM-4 will support XM Radio's direct broadcast of digital radio programming to cars, homes and portable radios throughout the continental United States and Canada. ...read more: here
