Inertial Measurement Unit

An inertial measurement unit or IMU is a composite sensor, which senses the motion of a body. Comprising three gyroscopes and three accelerometers arranged at right angles to one another, it attempts to track every change in position and axis.

IMUs work via the technique of dead reckoning, assuming that nothing has changed between measurement pulses. No matter how accurate they are, this leads to a slow compound error, where movement along one axis occurs when it is not being actively checked, or continues fractionally longer than believed. These4 errors stay permanently, moving position further and further outside the attested area, unless checked periodically by another method such as GPS.
