Los Angeles —"Roll" is the first of two satellites that Boeing Satellite Systems Inc. built for XM Satellite Radio Inc. (Washington, D.C.). The second satellite—designated "Rock"—is scheduled to launch this month. Together, the two spacecraft, "Rock" and "Roll," will change the way Americans listen to radio, according to BSS President Tig Krekel, delivering up to 100 channels of digital-quality music, news, and information to cars, homes, and other listening environments equipped with a small antenna. "Each satellite has the same coast-to-coast footprint to ensure maximum signal and system reliability to each XM Satellite Radio user," Krekel adds.
