Descripción : XM 2 (better known as XM ROCK) is an American geosynchronous radio broadcast satellite that was launched by a Zenit 3SL rocket from the Sea Launch Platform on the equatorial Pacific ocean at 22:33 UT. The 4.7 ton (with fuel), 18 kW satellite carries two transmitters (3 kW each) in the S-band to relay 100 channels of digital quality music uplinked in the X-band from one or more ground stations, after parking over 115 deg-W longitude. (It will be accompanied by XM ROLL due to be launched in May 2001.) The investors include several auto manufacturers who will be equipping the special receivers in their models.
