Abstract

Las audiodifusiones de alta calidad en las frecuencias de radio a receptores móviles en o cerca de la superficie de la tierra se proporcionan substancialmente por una transmisión simultánea de la misma señal desde dos satélites geosincrónicos separados espacialmente en la órbita geosincrónica la cual elimina el desvanecimiento de múltiples trayectos y la atenuación por el follaje, con lo cual se permite el uso de un segmento de espacio a bajo costo.
