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.
New value
New Synergy created in combination with MEMS & FOG
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 yhe concept of filling in the gap of cost and accuracy by combining MEMS gyro and FOG(optical fiber gyro).
Compound Navigation
What is GNSS/INS/VS navigation?
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.
Actual test
Case Study for GNSS/INS Navigation
Dead Reckoning, a method of calculating position with GNSS/INS combined navigation in GNSS-denied environment such as a tunnel. Please take a look at the demonstration from here.
