Global Positioning System (GPS) Jamming Situational Awareness for Naval Surface Fire Support (NSFS)

"The objective of this Phase I SBIR is to produce an architectural design for a system of GPS jammer geolocation collectors. The proposed system is called the Situational Awareness of GPS Environment (SAGE) system and is designed to operate using a networkof small UAVs, such as the Smart Warfighting Array of Reconfigurable Modules (SWARM) UAVs, as each jammer location sensor platforms. The SAGE system consists of a jammer location (JLOC) sensor on each UAV, and a shipboard master station that processes theJLOC sensor data to compute the jammer location and provides jammer situational awareness to the Naval Fires Control System (NFCS) using a Weapons Effectiveness Prediction Model (WEPM).The SAGE system provides a mission support capability to assess jammer effects on GPS-guided, precision strike weapons. The system leverages the proven NAVSYS Jammer Location capability previously developed under an Air Force SBIR. Under Phase I we willdevelop a design for a JLOC sensor payload suitable for installation on a small UAV and develop a design to upgrade our JLOC master station to include the WEPM capability to provide GPS situational awareness. As an option, we also propose to support ademonstration of a prototype SAGE system using in-house test equipment. Because of the susceptibility of GPS to interference there is a growing need for civil and Government agencies to be able to quickly locate sources of interference to GPS. The SAGE
