Delivering cutting-edge high performance IMU capabilities
The TopAxyz Inertial Measurement Unit (IMU) stands out as a cutting-edge solution designed by Thales, leveraging advanced technologies such as Ring Laser Gyro (RLG) to provide unparalleled performance in critical aerial, land, and naval transport applications. Comprising three laser gyroscopes and three accelerometers in a compact unit, the TopAxyz IMU ensures high-performance navigation by delivering accurate attitude, position, and speed information, vital for designation systems.
Enhancing Kalman filter integration and performance
Thales has engineered the TopAxyz IMU to streamline Kalman filter integration and boost overall performance. This approach enables compensating for individual sensor weaknesses by leveraging other sensors, thereby enhancing multisensor data fusion efficiency in both manned and unmanned platforms across naval, land, and airborne domains. The IMU's Ring Laser Gyrometer (RLG) boasts a simplified data model with high representativity in various environments, guaranteeing angular rate and acceleration measurements that are compensated for temperature variations and motion intricacies like coning and sculling.
Predictable behavior enhancing multisensor performance
TopAxyz IMU's unique predictability ensures optimal navigation resilience and performance by eliminating drift instability, which facilitates easy characterization valid under any condition. Through kalman multisensor data fusion, the IMU compensates for sensor weaknesses, ensuring high accuracy and resilience throughout missions. This predictable performance lays a solid foundation for the integration of artificial intelligence (AI) in navigation decision-making processes, ensuring safe and efficient outcomes.
Trusted performance for decisive moments
As the number of moving platforms increases in various domains, maintaining navigation integrity becomes crucial. TopAxyz IMU addresses this challenge by adhering to the highest safety-critical standards and incorporating comprehensive self-monitoring features derived from Failure Mode Analysis Effect (FMEA). This guarantees the highest level of trust and integrity in navigation data, essential for critical applications in airborne, land, and naval settings, while safeguarding against navigation spoofing.
Proven reliability and maintenance-free operation
Thales's TopAxyz IMU not only ensures reliable performance but also requires minimal maintenance, eliminating the need for calibration throughout its lifecycle. With an impressive Mean Time Between Failure (MTBF) exceeding 150,000 hours, validated through extensive operational hours since 2015, the IMU's reliability surpasses industry standards. Superior reliability and maintenance-free operation contribute significantly to enhancing system availability in operation and reducing total cost of ownership for customers.
Product availability and program support
Thales's mastery of critical technologies, from precision accelerometers to high-accuracy Ring Laser Gyrometers (RLG), ensures the top-notch design and manufacture of the TopAxyz IMU at advanced facilities in France. The IMU, utilized in major civilian and defense programs like the Airbus A350 and SCORPION for the French Ministry of Defense, is available with short lead times and comprehensive program support throughout its operational lifetime. Thales's commitment to continual innovation and support guarantees the reliability and effectiveness of the TopAxyz IMU for various applications.
