Inertial Measurement Units

Inertial Measurement Unit (IMU) sensors are designed to provide motion, position, and navigational sensing from a durable single device over six degrees of freedom. This is achieved by using either MEMS- (microelectromechanical system), FOG- (Fiber Optic Gyroscope) or RLG- (Ring Laser Gyroscope) technology to sense translational movement in three perpendicular axes (surge, heave, sway) and rotational movement about three perpendicular axes (roll, pitch, yaw). Because the movement and rotation along the three axes are independent of each other, such motion is said to have “six degrees of freedom.”
