Northrop Grumman Delivers GPS-Jamming-Resistant Airborne Navigation System
April 20, 2026 | Northrop GrummanEstimated reading time: 1 minute
Northrop Grumman delivered the first production unit of the EGI-M navigation system, designed to provide military users with accurate positioning, navigation and timing (PNT) data. The system is now modernized to support successful missions in high-conflict areas across the globe.
Upon full production, military customers will benefit from a unified hardware and software navigation solution that can be seamlessly integrated into platforms.
Key features include:
- Resilient and Trusted Navigation: The military-code PNT system, known as EGI-M, marks a significant advancement in airborne navigation technology by ensuring the reliability of navigation data in conflict zones. Further advancements include Blended Navigation Assurance, a capability that ensures GPS data is correct and safe, even when it’s threatened.
- Flexible Software: EGI-M was designed with future growth in mind. Operators can host third-party PNT apps without Northrop Grumman involvement to tailor navigation functions. This allows EGI-M to integrate other complementary sensors and track various, non-GPS satellites.
- Path to Production: The design has undergone rigorous hardware and software testing to meet military specifications and performance standards to prepare for full-scale manufacturing.
Experts:
Ryan Arrington, vice president, navigation and cockpit systems, Northrop Grumman: “Northrop Grumman has a strong legacy of delivering reliable and innovative navigation solutions to the U.S. military and our allies. Our latest modernized PNT system, EGI-M, enhances operational effectiveness and is built with the flexibility to defeat today’s threats and adapt to future mission demands."
Lt. Col. Chris Grover, U.S. Air Force: “This advanced, resilient PNT receiver allows our U.S. military assets the ability to go where we want to, with the capability we need, at the time of our choosing.
