A novel space system architecture is proposed that would enable 100-gram-class spacecraft to be flown as swarms (100s to 1000s) in low Earth orbit (LEO). Swarms of Silicon Wafer Integrated Femtosatellites (SWIFT) present a paradigmshifting approach to distributed spacecraft development, missions, and applications. Potential applications of SWIFT swarms include sparse aperture arrays and distributed sensor networks. New swarm array configurations are introduced and shown to achieve the effective

A system cost analysis based on this comparison justifies deploying a large number of femtosatellites for sparse aperture applications. Moreover, this paper discusses promising guidance, control, and navigation methods for swarms of femtosatellites equipped with modest sensing and control capabilities.
