The feasibility of providing Voice of America (VOA) broadcasts by satellite relay, rather than via terrestrial relay stations, was investigated. Satellite voice broadcast systems are described for three different frequency bands: HF (26 MHz), VHF (68 MHz), and L-band (1.5 GHz). Geostationary satellite configurations are considered for both frequency bands. A system of subsynchronous, circular satellites with an orbit period of 8 hours was developed for the HF band. The VHF broadcasts are provided by a system of Molniya satellites.
"This report comprises three volumes. Volume 1 is an Executive Summary. Volume 2 contains the technical results of the study, together with a life cycle cost summary. Volume 3, which is labeled proprietary, contains nonrecurring and first-unit cost estimates for the various satellite configurations generated during the study"--Preface.
