Knowledge Base for Distributed Spacecraft Mission Design Using the Trade-Space Analysis Tool for Constellations (TAT-C)

• Provide a framework to perform pre-Phase A mission analysis of Distributed Spacecraft Missions (DSM) o Handle multiple spacecraft sharing mission objectives o Include sets of smallsats up through flagships o Explore trade-space of variables for pre-defined science, cost and risk goals, and metrics o Optimize cost and performance across multiple instruments and platforms vs. one at a time • Create an open access toolset which handles specific science objectives and architectures o Increase the variability of orbit characteristics, constellation configurations, and architecture types o Remove STK licensing restrictions OBJECTIVES DEFINITIONS
