Navy Satellite Communications in the Hellenic Environment

Abstract

This thesis covers the history of satellite communications from its beginning in 1957 until recent years, describes the space subsystem and explains the major components of satellite communications. It defines the practical problems of satellite communications such as radiation and frequency dependence attenuation. It also examines certain aspects of satellite communications in the Hellas environment including reliability and survivability in a hostile environment. The last chapter outlines the major decisions and evaluation required for a tactical satellite system for the Hellenic Navy. Keywords: Frequency division multiple access, Time division multiple access, Spread spectrum multiple access, Ultrahigh frequency communications, Active passive satellite, Uplink downlink calculations.
