Introduction

High Precision & High Performance FOG INS

Introduction

ER-FINS-120 High Precision & High Performance FOG INS are all strap-down inertial navigation products. The basic components of the series of inertial navigation products are 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. The product 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.
