5 THINGS TO LOOK FOR WHEN EVALUATING AN INERTIAL MEASUREMENT UNIT (IMU)
There are many different types of IMU, the three most common types of IMU for mobile mapping applications are:
- Fibre Optic Gyro (FOG)
- Ring Laser Gyro (RLG)
- Micro Electro Mechanical Systems (MEMS)
Generally, FOG and RLG IMUs provide higher performance than a MEMS IMU, but this is not always the case. We highly recommend studying the specifications of each IMU carefully before deciding to ensure you get the right IMU for you.
