OWEGO, N.Y., – Lockheed Martin received a $25 million initial contract award for engineering and manufacturing development (EMD) for the GPS Spatial Temporal Anti-Jam Receiver (GSTAR) system that will be integrated into the F-35 as part of its modernization phase, also known as Block 4. The GSTAR system will replace the current Antenna Electronics Unit (AEU) and will provide enhanced capabilities including the next-generation, anti-jam solution and provide a significant weight and cost reduction to the aircraft.

GSTAR is one of several key enhancements planned across the F-35’s sensors, data links, engine, mission systems, weapons and more.

The GSTAR is a fully digital system that provides the greatest protection against adversarial jamming and spoofing by utilizing critical GPS capabilities that can quickly adapt to meet specific platform requirements. The GSTAR system includes a dynamic range radio frequency (RF) front-end, digital beamformer and receiver that has been tested and proven against a variety of threat scenarios.
