Introducing the µIMU: A Cutting-Edge Inertial Measurement Unit
The µIMU represents a state-of-the-art, compact inertial measurement unit (IMU) that features a fully enclosed design. It integrates three axes of MEMS gyroscopes and three axes of MEMS accelerometers, along with control and power electronics, all housed in a robust, hermetically sealed casing. With a digital RS-422/HDLC communication interface, this device is designed for seamless integration into various unmanned aerial vehicles (UAVs) and other unmanned systems. It excels in applications such as flight control, stabilization of antennas and cameras, and can be incorporated into more complex systems like Attitude and Heading reference Systems (AHRS).
Remarkable versatility and Performance
This low-size, weight, and power (SWaP) IMU delivers fully compensated data for temperature and alignment, ensuring high accuracy. It also boasts thorough built-in test (BIT) capabilities,making it a reliable choice for demanding applications. The µIMU is available in multiple configurations, catering to different performance and measurement range requirements.
