Introduction

ER-FOG-120 High Performance FOG Gyroscope

ER-FOG-120 high precision FOG gyroscope is a very important angular rate sensor, which has the characteristics of long life, fast start up, high precision and lower power consumption. It plays a very important role in precise north-seeking device, vehicle positioning orientation, high precision inertial navigation system (INS). The FOG gyroscope has no moving parts and doesn’t rely on inertial resistance to movement compared with other classic spinning-mass gyroscopes or mechanical gyroscopes. Hence, the FOG is an excellent alternative to a mechanical gyroscope.

Applications

Precise north-seeking

High precision inertial navigation system

Vehicle positioning orientation
