Investigation of the integration of a terrestrial communications network within a communications satellite system

The two FORTRAN IV computer programs SIKOME and SIKOMS are combined by their input/output and form in that way a computer program system. The programs simulate a communication system as to technic and costs. Alternatives are compared: a terrestrial network under consideration of the already installed telephone and TV-network; a communication satellite system with a geostationary satellite together with the needed number of ground stations. The user is able to decide between the services (telephone and TV-transmission) separately or combined. In case of telephone, a traffic model simulates the traffic between terminal exchanges. In case of TV, the transmission starts from a single TV center and runs via satellite to the different TV participants.
