Assessing the Impact of GPS Degradation Using Campaign-level Warfare Modeling
Navy SBIR 2007.2 - Topic N07-142 SPAWAR - Ms. Linda Whittington - linda.whittington@navy.mil Opens: May 14, 2007 - Closes: June 13, 2007 N07-142 TITLE: Assessing the Impact of GPS Degradation Using Campaign-level Warfare Modeling TECHNOLOGY AREAS: Information Systems, Battlespace, Space Platforms ACQUISITION PROGRAM: PMW-170 The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), which controls the export and import of defense-related material and services. Offerors must disclose any proposed use of foreign nationals, their country of origin, and what tasks each would accomplish in the statement of work in accordance with section 3.5.b.(7) of the solicitation. OBJECTIVE: To integrate an engineering-level simulation of GPS receivers with a constructive large-scale model to show the impact of denial and spoofing of GPS signals at the campaign level. Develop a relevant campaign scenario to demonstrate proof of concept. DESCRIPTION: The DoD has increasingly become reliant on the Global Positioning System for uses ranging from navigation, UAV control, precision weapons employment, ISR surveillance and targeting, and communications/network timing. Associated with this reliance is a growing threat capability to deny, degrade, or confuse GPS signals. While the DoD acknowledges this threat capability and the potential for it to be used in a hostile environment, GPS is still largely assumed to be intact in many military assessments. PHASE I: Explore automated ways of linking engineering-level GPS models with campaign-level constructive models to capture the dynamics of GPS degradation. Consider approaches such as High Level Architecture, XML, and web-based paradigms for passing data between the models. Define data elements to be shared and the ways these data will be used. Develop a relevant campaign scenario to demonstrate proof of concept. PHASE II: Using a relevant warfare scenario, model the impact of threat GPS denial through spoofing on US forces operating unmanned ISR platforms such as BAMS and UCAS-N. Coordinating with N8, SPAWAR 05, PMW-170 and other stakeholders, develop a study plan that outlines the study scope and objectives, the threat and US CONOPS, the modeling approach, the input data and data sources, and metrics that will be collected. Research data from approved sources such as N8 for authoratative scenario information, SPAWAR 05 for coordination with modeling and simulation interface models, and PMW-170 as the Navy's Navigation Program Office. Build a prototype application to test this arrangement. Execute the study and document the results in an annotated briefing. PHASE III: Perform a complete implementation of the prototype application developed in Phase II and expand it to capture the impact of threat spoofing on GPS weapons and sensors. Demonstrate the new capability in a more extensive scenario with an updated threat laydown. PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: The resulting product would provide a Modeling and Simulation environment that could be used to assess the impact of denied or degraded GPS signals on any user of GPS signals, from commercial aviation to academia. This capability could be used by the Department of Homeland Security to explore vulnerabilities to terrorist actions and by any company that relies on the GPS to develop mitigating strategies in the event of GPS signal loss.
