Dubhe-L1 Land Inertial Navigation System – High-Precision GNSS-Denied Navigation for Land Platforms

When land platforms operate in complex terrain, urban canyons, or GNSS-challenged environments, navigation accuracy is critical. The Dubhe-L1 Land INS / IMU is engineered to provide reliable, high-precision positioning, attitude, and heading information—anytime, anywhere.

Powered by advanced Ring Laser Gyroscope (RLG) and Fiber Optic Gyroscope (FOG) technology, paired with precision quartz accelerometers, the Dubhe-L1 combines:

• Fast adaptive alignment for rapid mission readiness

• Intelligent sensor fusion for stable, continuous navigation

• Zero-velocity updates to reduce drift during long missions or GNSS interruptions

Its rugged, compact design delivers consistent performance under extreme temperatures, shock, and vibration, making it ideal for:

• Armored vehicles and military ground platforms

• Autonomous land vehicles (UGV/AGV)

• High-speed rail and logistics vehicles

• Precision agriculture and industrial vehicles

Key Advantages:

• Accurate and stable navigation in GNSS-denied environments

• Seamless integration with GNSS, odometer, and auxiliary sensors

• Low power consumption with long-term reliability

• Designed for harsh terrain and continuous operation

The Dubhe-L1 Land INS delivers high-performance inertial navigation, giving operators confidence to move, navigate, and make mission-critical decisions without compromise.
