NTT domestic satellite communications system
Abstract
The NTT domestic satellite communications system is described, and its state of operation is discussed based on commercial service experience. The major parameters of the system and system satellites are given, and the transmission circuits between regional centers and between remote islands and the mainland are shown. The characteristics of the NTT earth stations are presented. Performance data are given to show the effect of rain attenuation and of sun transit on the satellite circuits.
