Inertial Measurement Units provide inertial attitude and velocity data to a spacecraft's guidance, navigation, and control system. On the space shuttle, IMU data are used to convert steering commands into control surface, engine gimbal, and...

An Inertial Measurement Unit, or IMU, is the main component of an inertial guidance system used in vehicles such as airplanes and submarines. An IMU works by sensing its own rate and direction of motion using a combination of accelerometers and...
