98A54003002004 is a high-precision aerospace inertial measurement unit (IMU), engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, tailored for navigation systems in Boeing 777X and Airbus A350 XWB wide-body aircraft during MRO and in-service operations.

Constructed from a lightweight, vibration-damped titanium alloy enclosure with an IP68 hermetic seal, it integrates 3-axis accelerometers (±0.001g accuracy) and gyroscopes (±0.005°/hr drift) to deliver real-time attitude and position data with a 200Hz output rate. Weighing 0.95 kg and measuring 100mm×80mm×60mm, it operates at -55°C to 125°C with a 25,000-hour MTBF. Compliant with FAA Part 25 and EASA CS-25 regulations, it ensures uninterrupted navigation accuracy for long-haul flights, even in GPS-denied environments, safeguarding aircraft positional stability and flight safety for commercial fleets.
