Embedded GPS/INS - Modernized (EGI-M)

Abstract

EGI-M is a combined INS/GPS aircraft position, navigation, and timing system. The program upgrades the legacy EGI design to enhance resiliency against existing and emerging adversarial navigational warfare threats. Design features, such as interface standardization and software modularity to incorporate alternative navigation and timing sources, aim to reduce DoD cost and timelines to respond to newly identified threats and enhance current force capabilities. EGI-M incorporates M-Code and Automatic Dependent Surveillance-Broadcast (ADS-B) Out compliance capability into EGI receivers while addressing parts obsolescence, reducing configuration count from 260+ to a desired end-state of 16, and decreasing production and sustainment costs. EGI-M has two prime contractors: Northrop Grumman and Honeywell. Both contractors required re-baselining given delays to Military Global Positioning Equipment (MGUE). Northrop Grumman has completed re-baselining and is executing accordingly while Honeywell has not.
