µIMU

Miniature three-axis MEMS inertial measurement unit

The µIMU is an advanced, compact and self-contained IMU that incorporates three MEMS gyros and three MEMS accelerometers in a rugged and hermetically sealed housing. Providing a digital RS-422/HDLC interface, it can be easily integrated into a variety of UAV and unmanned systems platforms, and is ideal for flight control, platform stabilization, and integration into higher-order systems such as AHRS.

The versatile IMU is available with a range of different performance and measurement range options.

FOG IMUs

Long-life cycle IMUs with modular configuration

Our FOG IMUs incorporate three axes of gyroscopes for rotational measurement and three axes of accelerometers for linear acceleration measurement, as well as processing electronics, power supply and I/O interfaces. In addition to this standard configuration, we can easily create custom designs to meet your specific requirements for UAV navigation, guidance and stabilization. Further performance enhancements can also be achieved via the integration of GPS and GNSS receivers to aid inertial navigation.

These advanced FOG sensors are free of moving parts, ensuring excellent resilience and reliability in high-shock and vibration environments and providing long service lifecycles without the need for periodic maintenance.

EF2000 IMU

Quadruple-redundant IMU with STANAG 3838 interface

Originally developed to provide attitude stabilization for the Eurofighter aircraft, the EF2000 is a quadruple-redundant IMU that delivers exceptional performance under challenging battlefield conditions. It provides continuous measurement of rotation and acceleration rates and calculation of attitude angles and direction, outputting data over a STANAG 3838 interface. With a modular design, the unit continuously self-monitors all functions, automatically diagnosing defective modules and managing redundancy to ensure the utmost in reliability and performance.

LCR-350B AHRS

High-accuracy MEMS AHRS with optional GNSS-aided capabilities

The LCR-350B is a MEMS-based AHRS (attitude and heading reference system) designed to provide the very best in safety and reliability in a compact and lightweight package. Outputting robust acceleration and rotation data as well as heading and attitude angles, it is ideal for both fixed-wing and rotary UAV platforms. The system can obtain heading reference from an external magnetometer, and can also output hybrid navigation data with the aid of an external GNSS source.

The rugged AHRS is designed to provide enhanced resistance against high-frequency radiation such as radar, and withstands high levels of shock and vibration. It utilizes an ARINC 429 interface and is certified in accordance with ETSO/TSO C-201 standards.
