Satellite communications (SATCOMs) [Part Two, NASA at 50]

NASA's R&D programs jump-started the SATCOM industry but were interrupted in 1973 in an attempt to get satellite manufacturers to conduct the research and development (R&D) necessary to satisfy their clients, the service providers. The technology provided by NASA would not have been affordable for public service users without this initial support. After being reinstated in 1978, NASA changed direction from public service technology demonstration to R&D support. The plan is to continue commercial communications support at a low level while focusing on the next generation of R&D in spectrum management and interoperability.
