LN-351 (EGI-M)
Embedded Global Positioning System (GPS)/Inertial Navigation System (INS) Modernization
Next Generation Airborne Navigation System
Northrop Grumman’s LN-351 is designed to offer maximum flexibility, addressing both challenging military requirements and civil interoperability capabilities, including DO-178C and DO-254 compliance. It ensures exceptional Positioning Navigation and Timing (PNT) reliability and unprecedented performance, covering navigation, pointing, stabilization and flight control applications.
Also referred to as the Embedded Global Positioning System (GPS)/Inertial Navigation System (INS) Modernization (EGI-M), the LN-351 incorporates an advanced navigation system utilizing fiber optics and Military-code (M-code), a robust, encrypted GPS signal tailored for military use, providing superior resistance to jamming and spoofing. This modern design enhances functionality in GPS-contested and denied environments, demonstrating resilience, and equipping platforms with reliable and precise navigation capabilities.

Applications
The LN-351 provides exceptional performance for navigation, geo-location of sensor targeting, and transfer align of remote sensors. With the lowest Angle Random Walk (ARW) in its performance class, the LN-351 achieves unequaled stabilization performance for use in SAR (Synthetic Aperture Radar), Active Electronically Scanned Array (AESA) Radars and Electro-Optical and Infrared Sensors (EO/IR) applications, as well as highly accurate target location. The system supports a wide variety of shipboard and undersea applications and is capable of AR-57 shipboard alignment.
Interface Options
The LN-351 is equipped with RS-422, ARINC-429, MIL STD 1553B, and Ethernet (10/100/1000T) interfaces. Additionally, future growth of the LN-351 will support Fiber-Optic, high-speed SerDes (serializer/deserializer) interfaces.
Growth
The LN-351 offers seamless integration capability and third-party application hosting. It features anti-jam GPS subsystems, beam-steering and nulling capabilities as well as growth provisions to apply Differential GPS (DGPS) corrections from various commercial formats, improving GPS accuracy.
