FALLS CHURCH, Va. Northrop Grumman Corporation has completed the critical design review (CDR) milestone for the Embedded Global Positioning System (GPS)/Inertial Navigation System (INS)-Modernization, or EGI-M, program.

EGI-M aims to provide state-of-the-art airborne navigation capabilities with an open architecture that is designed to enable 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 modular platform interface design is intended to enable backwards compatibility with existing platform footprint and interfaces (A-Kits), allowing current platforms to 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, is designed to allow EGI-M to benefit from rapid upgrades.

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.
