FOG & MEMS combined IMU incorporates 3-axis gyro (i-FOG for Z axis, MEMS gyro for X and Y axis) and accelerometers, which which measure angular velocity and acceleration. In addition, attitude (roll & pitch) and heading (yaw) is calculated. An external GNSS module is connected to IMU; with position and speed data, IMU can be used as GNSS / INS / VS navigation.
The accuracy of Gyroscope is classified by principle of operation.
The customer needs to choose the suitable gyroscope depending on its application or environment.
FOG & MEMS combined IMU is anewly developed IMU with the concept of filling in the gap of cost and accuracy by combining MEMS gyro and FOG(optical fiber gyro).

In GNSS-denied environment such as tunnel, or under multipath propagation caused by buildings, the accuracy of GNSS is deteriorated. FOG / MEMS IMU realizes a precise dead reckoning by GNSS, inertial sensor (INS) and vehicle speed (VS) combined navigation.
Introduction to a new inertial measurement unit TAG350, which is a fiber optic gyroscope and MEMS-IMU combined sensor.
