The DynaSat Information Architecture for Fractionated Satellite Systems
Joseph D. Touch, Gregory G. Finn, Goran Scuric, Michael Elkins, Richard Shiffman · 2012
DynaSat is a dynamic satellite information architecture that supports adaptive, faulttolerant, and secure communication and resource sharing for distributed (fractionated) satellite systems. It supports safe, robust, and secure sharing and virtualization of both cluster and ground capabilities by combining a COTS secure hypervisor and trusted resource control and multiplexing software with secure overlays. DynaSat leverages USC/ISI’s X-Bone overlay network and NetStation distributed PC architecture systems to deliver a space-based Internet for distributed satellite data collection applications. The result is a configuration-based approach that enables rapid implementation, simple operation, and provides programmers a familiar Internet-based environment. The architecture also supports service import/export to external ground users. This document provides an overview of the DynaSat architecture, discusses its design and resulting capabilities and advantages for fractionated satellite systems.
