Abstract

High quality audio broadcasts at radio frequencies to mobile receivers at or near the earth's surface are provided by sub-stantially simultaneous transmission of the same signal from two geosynchronous, spatially-separated satellites (#1 and #2) on the geosynchronous orbit which virtually eliminates multipath fading and foliage attenuation and thereby permits the use of a low-cost space segment.
