Spectrum/Orbit Utilization Program for Geostationary Satellites

Mutual interferences among geostationary satellite communication systems determine the permitted spacing between satellites and the limits on the capacity of the orbit/spectrum resources available. This paper describes the "Spectrum/Orbit Utilization Program," a computer program for analyzing the mutual interferences among communication satellite systems. Capabilities of the program are described. Inputs, models used, program operations, and program outputs are given. To show application of the program, an example scenario is analyzed for fixed satellites providing domestic service to North America.
