A genetic algorithm optimization scheme for planning satellite earth station antenna layouts is presented and analyzed. The problem of quantifying the value of a layout containing large parabolic antennas is described and developed. Genetic algorithms are used with the method of quantifying antenna layouts to find a locally optimal site plan. This scheme allows for the optimal placement of large parabolic antennae within a bounded geographic area, such as a building rooftop or property boundary, ensuring the best use of valuable earth station real estate. Performance of the optimization scheme is verified by simulation results in two different scenarios. The scheme is tested while developing a completely new site layout, and also while expanding on an existing, most likely sub-optimal, site layout. The scheme successfully placed the antennas to provide good satellite arc coverage without any human input.
