Miniature inertial measurement unit

Miniature inertial measurement unit (MIMU) is an inertial measurement unit (IMU) developed and built by Honeywell International^[2] to control and stabilize spacecraft during mission operations. MIMUs can also be configured to perform as an inertial reference unit (IRU). MIMUs have been flown on GEO, Low Earth orbit (LEO), planetary missions and deep-space-probe applications.
