Introduction

High Performance & Ultr-High Precision FOG Gyroscope (Φ120mm)

ER-FOG-120H Ultr-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. 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 which plays an important role in precise north-seeking device, vehicle positioning orientation and high precision inertial navigation system (INS).

Applications

Precise north-seeking

High precision inertial navigation system

Vehicle positioning orientation
