Mobile satellite communications technology - A summary of NASA activities
Author and Affiliation:
Dutzi, E. J.(California Institute of Technology, Jet Propulsion Laboratory, Pasadena, United States)
Knouse, G. H.(NASA Washington, DC, United States)
Abstract: Studies in recent years indicate that future high-capacity mobile satellite systems are viable only if certain high-risk enabling technologies are developed. Accordingly, NASA has structured an advanced technology development program aimed at efficient utilization of orbit, spectrum, and power. Over the last two years, studies have concentrated on developing concepts and identifying cost drivers and other issues associated with the major technical areas of emphasis: vehicle antennas, speech compression, bandwidth-efficient digital modems, network architecture, mobile satellite channel characterization, and selected space segment technology. The program is now entering the next phase - breadboarding, development, and field experimentation.
