“The completion of this milestone is a key step in bringing necessary navigation capability upgrades to our warfighters,” said Brandon White, vice president, navigation and positioning systems, Northrop Grumman. “With its open architecture and government ownership of the key internal interfaces, EGI-M’s next generation navigation solution allows the government to quickly insert emerging capabilities from 3rd parties while maintaining cyber security and airworthiness.”

EGI-M provides state-of-the-art airborne navigation capabilities with an open architecture that enables rapid responses to future threats. The fully modernized system integrates new M-Code capable GPS receivers, provides interoperability with civil controlled air space, and implements a new resilient time capability.

Northrop Grumman’s unique, modular platform interface design enables backwards compatibility with existing platform footprint and interfaces (A-Kits), allowing current platforms to easily integrate and deploy Northrop Grumman’s EGI-M solution. At the same time, EGI-M’s modular software / hardware, coupled with government ownership of key interfaces, allows EGI-M to benefit from rapid upgrades with best of breed software and hardware technologies now and in the future.

Northrop Grumman has been on contract for the engineering and manufacturing development (EMD) phase of EGI-M since November 2018. The CDR milestone marks the completion of detailed hardware and software design of the EGI-M product line. The launch platforms for Northrop Grumman’s EGI-M are F-22 and E-2D. Additional fixed-wing and rotary-wing platforms across Department of Defense and allied forces have already selected Northrop Grumman’s EGI-M as their future navigation solution.
