It is critically important that a physics based ADR SAAT prototype be developed that can be refined and used across the community to study and analyze various remote (non-contact) orbital debris stabilization concepts and architectures prior to investing significant commercial or public funding into technology development, technology and system level demonstrations, and development and deployment of an Orbital Debris Stabilization/ADR system. Under this STTR, PA&S plans to develop a prototype Active Debris Removal System Architecture Analysis Tool (ADR SAAT) that we will use as the basis for the detailed architectural and business case analysis. The focus of this effort will be to selected and implement a core integrated architecture framework based on a SOA, adapt it as necessary, and develop the initial models, functions and interfaces necessary to develop the ADR SAAT prototype. The goal will be to provide the tool to NASA for community-wide development and use and which PA&S can adapt and use for detailed architectural analyses to define operating parameters, costs, and system level requirements. The intent of a Phase II effort would be to validate ADR SAAT with ground or flight experiments, continue to enhance its capabilities, and for detailed Debris Stabilization / Active Debris Removal Architecture analysis.
