Evaluation of SANDGT Using SOA Framework for Persistent and Risk-Averse Space Situation Awareness

ABSTRACT: Space superiority needs protected tactical space communications with dynamic spectrum sharing, routing adaptation and interference mitigations against kinetic and non kinetic threats. The main focus of this project is to develop game-theoretic analytics and frameworks to support the Air Forces autonomy science & technology strategy (e.g., "deterrence" posture which in turn may be enabled by the attribute of resiliency) against counter space aggression. The Phase I effort has resulted in a SANDGT for persistent and risk-averse space situation awareness. We obtained the promising results to validate our developed approaches. These preliminary yet promising results clearly demonstrate that IFTs SANDGT provides innovative and effective game theoretical approach for persistent space denial. In the phase II project, we will revise, extend, and optimize the Phase I research results for realistic SSA scenarios considering the security issues in embedded satellite networks with Service-Oriented-Architecture (SOA) framework and the operational constraints of space-based visible/radar sensors, LEO/near GEO space platforms, maneuver capabilities, characteristics of orbital planes and space assets per plane on asset observability and reachability. Moreover, IFT team will extend and tie all the models developed in Phase 1 using SOA framework and Observe, Orient, Decide and Act (OODA) decision making paradigm.; BENEFIT: The proposed SANDGT for persistent and risk-averse space situation awareness has tremendous application potential in many military applications. It can be used to defensive counter space mission to protect high value space assets, and protect tactical space communications with dynamic spectrum sharing, routing adaptation and interference mitigations against kinetic and non kinetic threat. The near term DOD application target is the Air Force programs, SSN-space surveillance network, SBSS-the Space Based Space Surveillance system, SBIRS-Space-Based Infrared System program, WGS-Wideband Global SATCOM, JSARS-JSPOC Situational Awareness Response System, DCGS-X-Distributed Common Ground System program (Air Force), and JSTARS-joint surveillance and target attack radar system. Other potential commercial applications include monitoring the civilian networks, such as finance, medicine, communications, electric power, nuclear energy, internet service provider, air traffic control, etc. In addition, police and first responders for NASA, US Coast Guard, Department of Homeland Security, multi-layered sensing, disaster assessment, air traffic control system, the national weather service, physical security systems, law enforcement agency, emergency control center, border and coast patrol, pollution monitoring, remote sensing and global awareness could be a potential application.
