µIMU Inertial Measurement Unit
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.
