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. [ Installation Request ](https://intel.airteam.eu/request) ## 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. #### Solutions - [Border Control](https://intel.airteam.eu/surveillance-border-control) - [Maritime Patrol](https://intel.airteam.eu/surveillance-maritime-patrol) - [Law Enforcement](https://intel.airteam.eu/surveillance-law-enforcement) - [Airborne Drone Detection](https://intel.airteam.eu/surveillance-airborne-drone-detection) - [Env. & Infrastructure Monitoring](https://intel.airteam.eu/surveillance-environmental-infrastructure-monitoring) - [Force Protection](https://intel.airteam.eu/surveillance-force-protection) - [Laser Scanning](https://intel.airteam.eu/surveying-mapping-laser-scanning) - [Photogrammetry](https://intel.airteam.eu/surveying-mapping-photogrammetry) - [Hyperspectral Imaging](https://intel.airteam.eu/surveying-mapping-hyperspectral-imaging) - [Corridor Mapping](https://intel.airteam.eu/surveying-corridor-mapping) #### Solutions - [Medevac](https://intel.airteam.eu/emergency-services-medevac) - [HEMS](https://intel.airteam.eu/emergency-services-hems) - [SAR](https://intel.airteam.eu/emergency-services-search-rescue) - [Disaster Relief](https://intel.airteam.eu/emergency-services-disaster-relief) - [Firefighting](https://intel.airteam.eu/emergency-services-firefighting) - [Env. & Resource Monitoring](https://intel.airteam.eu/emergency-services-environmental-resource-monitoring) - [Wildlife Monitoring](https://intel.airteam.eu/emergency-services-wildlife-monitoring) - [Pipeline & Powerline Monitoring](https://intel.airteam.eu/emergency-services-pipeline-powerline-monitoring) - [Oil Spill Detection](https://intel.airteam.eu/emergency-services-oil-spill-detection) #### Technologies - [Sensors](https://intel.airteam.eu/sensors) - [Communication](https://intel.airteam.eu/communication) - [Avionics](https://intel.airteam.eu/avionics) - [Lighting & Visual Solutions](https://intel.airteam.eu/lighting-visual-solutions) - [Specialized Cargo Solutions](https://intel.airteam.eu/specialized-cargo-solutions) - [Equipment & Accessories](https://intel.airteam.eu/equipment-accessories) - [Mission Workstations](https://intel.airteam.eu/mission-workstations) - [Unmanned Systems](https://intel.airteam.eu/unmanned-systems) #### Other - [Operator Workstation](https://intel.airteam.eu/operator-workstation) - [Mission Control Unit](https://intel.airteam.eu/mission-control-unit) - [Mission Displays](https://intel.airteam.eu/mission-displays) - [Capabilities](https://intel.airteam.eu/capabilities) - [Completed Projects](https://intel.airteam.eu/completed-projects) #### About us - [Facebook](https://www.facebook.com/airteamcz) - [Instagram](https://www.instagram.com/airteameu/) - [LinkedIn](https://www.linkedin.com/company/air-team-eu) © 2025 AIR TEAM Intel, s.r.o. | [GDPR Policy](https://intel.airteam.eu/personal-data-protection) | Cookie Settings | [webdesign AETO](https://aeto.cz) [Follow us on Facebook ](https://www.facebook.com/airteameu) [Follow us on Twitter ](https://www.instagram.com/airteameu/) [Follow us on Facebook ](https://www.linkedin.com/company/airteameu)
