Northrop Grumman Corp. completed the critical design review of an upgraded navigation system for U.S. military aircraft.

The engineering and design work on the Embedded Global Positioning System (GPS)/Inertial Navigation System (INS)-Modernization, or EGI-M, program was done in Woodland Hills. The navigation system is for the U.S. Air Force’s F-22 Raptor and the Navy’s E-2D Advanced Hawkeye aircraft.

Brandon White, vice president of navigation and positioning systems for the global aerospace and defense contractor, said that completing the review is a key step to bringing navigation capability upgrades to the county’s fighters.

“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 third parties while maintaining cyber security and airworthiness,” White said in a statement.

The critical design review milestone marks the completion of detailed hardware and software design of the EGI-M product line. The EGI-M uses an open architecture that allows for rapid responses to threats and its modern system integrates new M-Code capable of communicating with global positioning systems.
