This series of inertial navigation products are all strap-down inertial navigation products. This series of products can be divided into high precision inertial navigation products, medium precision inertial navigation products and low precision inertial navigation products.

 High Precision Inertial Navigation System

The basic components of this series of inertial navigation products are composed of three optical fiber gyroscopes of corresponding grade, three quartz flexible pendulous accelerometer, navigation computer circuit, information processing circuit, current frequency conversion circuit, power changing device, structural platform/structural box and vibration damping device. 

This series of products can be used for real-time measurement of three translational information and three moving information of various aircraft or moving objects, and can output real-time navigation information such as angular increment, apparent velocity increment, attitude, speed and position of the carrier. This series of products have the characteristics of wide dynamic working range, strong adaptability to the environment and comprehensive navigation information.
