Type 50 LASER Strapdown Inertial Navigation System
Product description
The Model 50 Inertial Navigation System is a state-of-the-art navigation solution. It combines the Type 50 Ring Laser Gyroscope and Quartz Flexible Accelerometer. This system can be integrated with GNSS, altimeters, and airspeed meters to provide accurate navigation information such as speed, position, and attitude for air and ground carriers. It is suitable for various applications including tanks, armored vehicles, aircraft, drones, ships, and more. The system achieves high accuracy with a positioning accuracy of less than 5 meters when integrated with GNSS. It has an alignment time of under 10 minutes and operates continuously for over 10 hours. The system features multiple interfaces and can withstand challenging environmental conditions. Compact and lightweight, it is a reliable and versatile solution for navigation needs.
