Devices to Counter GPS-Jamming

The Technology

SARA and the Air Force Research Laboratory (AFRL/MNGN) have developed the Geolocation on GPS Jammers (GOGJ) system to locate GPS jammers with a low-cost, timely solution.

The Phase II GOGJ system consists of an Osprey UAV, SARA's Geolocator/Seeker, a Piccolo autopilot, and a CMIGITS navigation system.

The system can perform homing and fly-over of the jammers to collect photos for additional situational awareness.

SARA is adapting its homing technology to GOGJ's specific geolocation needs.

The Applications

SARA’s Phase II GOGJ system detects and precisely 3D geolocates multiple GPS jammers without prior knowledge of the threat and reports their locations to users on a map display.

GOGJ performs intelligence, surveillance, and reconnaissance (ISR) missions, while retaining homing capability.

The system can perform homing and fly-over of the jammers to collect photos for additional situational awareness.

The Seeker technology has been rendered into a flight-tested prototype for a home-on-GPS jammer (HOGJ) mission.

The Advantages

• The GOGJ system is platform independent.
• There is no practical limitation on the number of GPS jammers.
