Publisher Summary 1
An electronics engineer working on satellite communications architecture designs for the US military at Fort Meade, Maryland, Jo introduces systems engineering approaches to modern satellite networks that provide wideband communications services through satellites, Earth stations, terminals, and terrestrial networks. Recent dramatic increases in both the availability of the technology and demand, he says, make it essential to map out feasible ways of providing secure, world-wide, reliable network-centric data service. He assumes readers have a fundamental knowledge of information systems and architectures, telecommunications networks, and telecommunications standards and protocols. Advanced calculus would be nice, but is not required. Some of the material is based on notes for a graduate course he taught at Johns Hopkins University.
