Analog Devices (ADI) inertial measurement unit (IMU) sensors are based on multi-axis combinations of precision gyroscopes, accelerometers, magnetometers, and pressure sensors. ADI's technology efficiently detects and processes multiple degrees of freedom, even in very complex applications and under dynamic conditions. These plug-and-play solutions include full factory calibration, built-in sensor compensation and processing, and a simple programmable interface.
Autonomous navigation systems (inertial navigation system, also known as ADIRU) are based on an IMU (Inertial Measurement Unit) manufactured by high end technology innovations firms with RLG (Ring Laser Gyro) technologies. This product is a concentrate of high technologies with performances adapted to all aeronautical applications but also land and sea. Very compact, it nevertheless embeds 3 laser gyros and 3 accelerometers in an optimized system to guarantee performance and increase its lifespan.
A unique architecture for very high performance
Its architecture is unique in the world with two information channels instead of just one. A “navigation” channel is dedicated to the calculation of attitudes, heading, speed and position. The other so-called "stabilization" path is optimized to provide low-delay, low-noise, zero-frequency accelerations and rotations without any unwanted frequencies in the bandwidth sought by the electric flight controls or the servo-controls of on-board optical sighting instruments.
Already on board with new advanced technologies
L’histoire de la navigation inertielle chez Thales a débuté il y a plus de 30 ans et de nombreuses plateformes embarquent des systèmes inertiels (Mirage 2000, Ariane 5, hélicoptères Tigre, C130, MIG29, etc.). Plus récemment, ce sont les A350 XWB d’Airbus, les ATR-600 et les KC-390 d’Embraer qui ont sélectionné ces systèmes. En 2016, TopAxyz IMU a été sélectionnée pour être embarquée sur les véhicules blindés Jaguar.
