Inertial Measurement Units (IMUs) are electronic devices that allow precise measuring and reporting of an object’s position in space. They are typically used for navigation purposes in aircraft and spacecraft. More recent uses include the production of IMU-enabled GPS devices which enable a GPS to work when GPS signals are unavailable, such as in tunnels or inside buildings. Epson Europe Electronics GmbH has been developing this highly promising market since 2012, bringing together its core competences in timing devices and semiconductors.
