Northrop Grumman LN-251 INS

The Northrop Grumman LN-251 is a high-precision, advanced Inertial Navigation System (INS) and Global Positioning System (GPS) Embedded GPS Inertial (EGI) solution designed for demanding airborne applications. It provides accurate, reliable, and resilient navigation performance for a variety of platforms, including military aircraft, unmanned aerial vehicles (UAVs), and other aviation systems that require high-performance navigation. The LN-251 is engineered to meet the strict requirements of modern missions that demand continuous, real-time position, velocity, and time (PVT) information in GPS-denied environments.

Advanced Navigation and High Accuracy

The LN-251 INS/GPS combines state-of-the-art strapdown inertial sensors with dual-frequency GPS receivers to deliver precise navigation data, even in environments where GPS signals may be degraded or unavailable. Its highly reliable inertial measurement unit (IMU) is designed to provide accurate and consistent data with minimal drift over time, ensuring mission success even in harsh operating conditions. The system supports high-integrity positioning with precise attitude, heading, and acceleration data, and is capable of providing continuous updates at high data rates for real-time application demands.

Compact, Reliable, and Versatile for a Range of Platforms

The LN-251 is designed to integrate seamlessly into various airborne platforms, from tactical military aircraft to commercial and unmanned systems. With its lightweight and rugged form factor, it offers flexible integration with minimal space and power consumption requirements. The system includes built-in redundancy and fail-safe mechanisms to ensure continuous operation, even under extreme conditions, making it ideal for both peace-time and combat operations. The LN-251 is also built to handle dynamic environments, from aerial refueling to high-speed flight, delivering precise and reliable navigation data no matter the mission profile.

The LN-251 is trusted by defense agencies and commercial operators alike for its versatility, ease of integration, and long-term reliability. It also includes advanced capabilities such as in-flight alignment, sensor fusion, and GPS anti-jamming to provide enhanced mission assurance.
