Model-Based Heterogeneous Optimal Space Constellation Design

Few tools exist for designing constellations of heterogeneous satellites. A new modular tool for total mission design of heterogeneous constellations, including spacecraft design, orbit selection, and launch manifestation, is proposed. The component modules and algorithms are discussed, including a novel crossover method for genetic algorithms and a novel constraint formulation for launch manifestation of maneuverable vehicles. Finally, the expandability of the tool to multiple domains and various applications is highlighted. The main benefit of the described tool is that it allows analysts to quickly and easily design complex system architectures for space systems with a variety of objectives, providing cost savings and enabling timely responses to changing mission needs.
