Abstract : Satellite communication systems based on the use of satellites in random orbits require large numbers of satellites to assure low probabilities of outage for the various links sharing the satellite overlay. The minimization of total cost of the satellite overlay required is expressed in terms of an interger programming problem, that is a linear programming problem with the added restriction that all the variables involved must be integers. Through use of this technique, it is possible to satisfy the requirements of any pattern of ground stations simultaneously using a mix of satellites at various orbital altitudes and inclination angles at a minimum cost of system establishment. The technique is demonstrated for a specific system of 34 Ground stations and 48 links. (Author)
