| NEXT GENERATION DIGITAL RADIO - One of the two telescoping solar wings aboard "Roll," a powerful Boeing 702 satellite built for XM Satellite Radio, Inc., is shown in the Boeing Satellite Systems factory. An 18-kilowatt spacecraft, Roll carries a unique digital audio radio payload that features two active transponders, each with 16 active (and six spare) 228-watt traveling wave tube amplifiers generating approximately 3,000 watts of RF power. The powerful satellite will operate in geosynchronous orbit at 85 degrees West longitude. The satellite has two 16.4 ft folding deployable S-band transmit reflectors and one X-band global receiver antenna. When fully deployed, the solar wings span 132.5 feet and the antennas to 46.6 feet. The satellite weighs approximately 9,800 pounds at launch and 6,500 pounds in orbit.
