Type 70 LASER Strapdown Inertial Navigation System
Product description
The RL70 Inertial Navigation System is a high-performance solution based on the Type 70 Ring Laser Gyroscope and Quartz Flexible Accelerometer. It seamlessly integrates with GNSS, altimeters, and airspeed meters, providing accurate navigation information for air and ground carriers. This system is suitable for tanks, armored vehicles, aircraft, drones, ships, automobiles, high-speed rail, unmanned vehicles, satellite communication systems, and drilling operations. It ensures precise navigation with a CEP of 0.6 nmile in pure inertial mode and less than 5m in integrated GNSS mode. The system offers exceptional accuracy in heading angle, horizontal attitude (roll and pitch), pure inertial velocity, and GNSS integrated velocity. With its reliability and versatility, the RL70 is the ideal choice for various navigation applications.
