Abstract

Previous research has evaluated different EPS topologies from efficiency, reliability, and cost perspectives, but has yet to incorporate orbital dynamics and mission attitude constraints into the overall evaluation of the most effective eps topology for a specific mission's needs. For efficient system architecture design, systems engineers must quickly assess the orbit-average maximum load that can be accommodated based on the orbit, pointing constraints, solar array collection area, and EPS efficiency to determine operational feasibility. The authors present preliminary findings showing that attitude constraints and the inclination/β-angle have significant effects on the available energy the spacecraft can capture and the size of the load the spacecraft can support.
