Intertial Measurement Unit

This device was part of the inertial measurement unit for the Space Shuttle orbiter. It provided a stable platform for the Shuttle's guidance, navigation, and control, using a set of high-precision gyroscopes and accelerometers. It uses a system of four gimbals to maintain a fixed position in space regardless of any movements of the Orbiter. It is probably flown hardware. The device was transfered from NASA in 2014.
