Northrop Grumman has handed over the first production example of its next-generation airborne navigation system, engineered to preserve positioning, navigation, and timing (PNT) capabilities in GPS-contested environments. Known as the Embedded Global Positioning System/Inertial Navigation System – Modernization, the solution combines satellite-based positioning with inertial navigation technology to deliver uninterrupted location data even when GPS signals are unreliable.
The system is tailored for high-threat environments where electronic warfare tactics—such as signal jamming and spoofing—are increasingly prevalent. Its updated configuration introduces advanced data validation features, including a “blended navigation” approach that cross-checks GPS data against multiple onboard inputs to improve accuracy and guard against compromised signals.
Built on a modular software architecture, the EGI-M allows seamless integration of external applications and sensors, reducing dependency on the original manufacturer. This design ensures adaptability for future enhancements and compatibility with emerging navigation systems beyond conventional GPS networks.
With the delivery of its first production unit, the program is now moving into full-scale manufacturing following successful qualification testing. Earlier milestones include successful operational trials in 2023 demonstrating performance under jamming conditions, as well as a critical design review completed in 2020 that confirmed the system’s robustness against signal interference.
