Designing the orbit of an Earth observing satellite is generally tedious work. Typically, a large number of numerical coverage simulations are run to understand the impact of orbital parameters on sensor performance and coverage characteristics. There is little guarantee of determining the optimal orbit for a given mission. Some work has been done to wrap an optimization loop around traditional numerical coverage simulations however, the computational resources necessary for this can be prohibitive. A methodology of determining optimal orbital characteristics without requiring a large amount of computing is presented. Several existing methods are used to calculate an approximation to total pass time and average number of passes per day given a satellite s orbital altitude and inclination. These are used along with particle swarm optimization to determine optimal orbit parameters. This methodology only pertains to a single satellite in a circular orbit.
