Northrop Grumman LITEF is showcasing its series of land navigation systems at Singapore Airshow 2026, February 3-8, 2026, BDLI German Pavilion, C-M78, designed to maintain high-precision performance during multi-domain operations in electronic warfare environments.
The LITEF Land Navigator (LLN) product line features three distinct systems, the LLN-GY, LLN-G2, and LLN-GZ, engineered to provide accurate data even when GNSS signals are subjected to spoofing or jamming. These systems focus on a balance of precision and modularity, avoiding unnecessary over-engineering to meet specific mission requirements.
The LLN-G2 utilizes Fiber Optic Gyro (FOG) technology to achieve very high pointing, navigation, and timing performance. The LLN-GZ is a compact, tamper-proof system based on Micro-Electro-Mechanical Systems (MEMS), while the LLN-GY serves as a cost-effective dead-reckoning solution with optimized sensors.
Kai Dlouhy, Director Defence at NG LITEF, said, “In times of increasing electronic threats, you need navigation that you can rely on even under the most difficult conditions. Our LLN systems have been developed precisely for this purpose – cost-efficient, battle-tested, and future-proof.”
To ensure resilience against modern electronic threats, the LLN-GZ and LLN-G2 integrate intelligent Kalman filter algorithms. The LLN-GZ is further compatible with NATO Generic Vehicle Architecture (NGVA) standards and can be paired with ERGR2M receivers and CRPA antennas. Despite their different internal technologies, the systems share high commonality in mechanical and electrical interfaces to allow for plug-and-play integration.
Leveraging over 35 years of experience in inertial navigation, NG LITEF produces these systems with high vertical integration, including in-house chip production. The technology is ITAR-free and utilizes software-defined defense principles to allow for continuous performance enhancements.
The company focuses on delivering solutions tailored to actual operational requirements rather than theoretical maximums. These German-made systems provide genuine jammer resistance under Navigation Warfare (NAVWAR) conditions, offering a high price-performance ratio for modern military land operations.
