inertial measurement unit

Space Exploration

An instrument that aids spacecraft navigation by measurements using computer-assisted gyroscopes and accelerometers. Connected to the spacecraft by gimbals (swivelling devices), IMUs establish a fixed base from which the spacecraft's attitude in space can be measured. In the Gemini spacecraft, the gyroscopes were mounted at right angles to one another to calculate the vehicle's pitch, yaw, and roll. The accelerometers were mounted in tandem with them to measure the vehicle's reaction to thrusters being fired.

Electronics and Electrical Engineering

A sensor system that measures acceleration and rotation by using a combination of gyroscopic sensors and accelerometers, usually having three of each. IMUs are chiefly used in inertial navigational systems designed to determine global location and velocity. As all their sensors can be of solid-state manufacture, they are commonly found in smartphones and tablet computers. They are also used in various gaming sensors, and to support automatic stabilization for consumer and commercial drones.
