N2 - Fractionated space systems are possibly the next paradigm in satellite design. Their architectural benefits such as flexibility, adaptability, and security, are often overshadowed by their higher mass and power requirements. While these drawbacks can be overcome through technological improvements, the possible increase in system complexity and therefore risk, are largely due to the system architecture. In this paper, three metrics for structural complexity, based on the concept of graph energy are evaluated using a series of fractionated satellite architectures. The effects of number of payloads within the fractionated system, component complexity and interface complexity for both internal and external wireless connections are presented. All the metrics are positively correlated to the total number of payloads, negatively correlates to the density of the architecture, and have different behaviors when the complexity of the components and interfaces is changing.
