A common user system to provide domestic and regional telecommunications services in year 2000

The worldwide demand for telecommunication services, country by country, is estimated on the basis of a study done by EUROSAT (1978), and the resulting traffic estimates are translated into the required number of satellite transponders. A common user system is then suggested in which access to orbital resources would be available to all users whose requirements fall below a certain number of transponders. Feasible configurations for such a system using INTELSAT V and INTELSAT VI class satellites are presented.
