The µIMU is an advanced, compact and fully enclosed IMU that incorporates three axes of MEMS gyroscopes, three axes of MEMS accelerometers, and control and power electronics in a rugged and hermetically sealed housing. Providing a digital RS-422/HDLC communications interface, it can be easily integrated into a variety of UAV and unmanned systems platforms, and is ideal for flight control, antenna and camera stabilization, and integration into higher-order systems such as AHRS.
The versatile and low-SWaP IMU outputs fully temperature- and alignment-compensated data and features extensive BIT (built-in test) capabilities. It is available in a range of different performance and measurement range options.
