Abstract: For efficient use of the geostationary satellite orbit, mutual interference among satellite systems must be analyzed in the planning stage of the systems. To conserve the transmitter power, many satellite antennas in the FSS (fixed–satellite service) use the so–called shaped–beam emission patterns that cover their service areas. A computer model of a shaped–beam pattern is needed in the analysis of mutual interference. We present a simple model for calculating the antenna gain in the direction of an earth point from several contour lines given on the map of the Earth, each corresponding to an antenna gain value.
