Northrop Grumman to upgrade software for the LN-251 navigation system on the CH-53K helicopter

Northrop Grumman Corporation (NYSE:NOC) has been awarded a Phase II contract by the U.S. Navy to modify existing software for the LN-251 embedded GPS/fiber-optic inertial navigation system (INS) on the new CH-53K Super Stallion helicopter.

The $5.6 million contract to support integration of the LN-251 system was awarded by the Naval Air Systems Command (NAVAIR), based in Patuxent River, Md. Northrop Grumman's Navigation Systems Division will provide updated software and engineering support for platform integration and flight tests to both NAVAIR and Sikorsky Aircraft, which manufactures the CH-53K helicopter. The Super Stallion helicopter is entering the ground and flight testing phase and will be the world's premier heavy-lift helicopter for the U.S. Marine Corps.

"The LN-251 is renowned for its compact size, light weight and high reliability," said Gorik Hossepian, vice president of navigation and positioning systems for Northrop Grumman's Navigation Systems Division. "This high-performance navigation system will further enhance the CH-53K helicopter's robust capabilities."

The LN-251 system is the world's smallest, lightest navigation-grade embedded GPS/INS unit in its class. Its fiber-optic, gyro-based inertial measurement unit offers a compact, low-noise solution for optimal sensor stabilization and navigation applications. The LN-251 system's modular, open architecture supports additional applications and evolving requirements.
