SPECTRUM FOR AREA COVERAGE FROM SATELLITE RELAYS TO SMALL TERMINALS,

Abstract

Mobile and broadcast services are typical of those involving small terminals, but the potential number of earth terminals is so large that the technology is inconceivable that would make feasible a separate independent satellite antenna beam to each earth terminal. For this situation practical systems could provide area coverage that would accommodate all the earth terminals within the coverage area. The specification of flux density required at the earth's surface over the coverage area will then determine the total RF power that must be generated in the satellite relatively independently of the number of beams that are used to cover the area.
