WorldSpace broadcasts from two satellites- AfriStar and AsiaStar, which were successfully launched in October, 1998 and March, 2000, respectively.
WorldSpace satellites are "geostationary", orbiting over the globe in fixed positions more than 35,000 kilometers above the equator. Using powerful spot beams, the satellites transmit to three overlapping coverage areas approximately 14 million square kilometers each. Each beam separately transmits 40 audio or multimedia channels.
Back on the ground, each satellite is supported by three major components: the Regional Operations Center (ROC); Telemetry, Command and Ranging (TCR) Stations; and Communications System Monitoring (CSM) Stations. Each component plays a major role in ensuring the best possible digital signal is received throughout the WorldSpace System. 24-hour monitoring by our dedicated team of professionals further ensures uninterrupted signal quality. |
