High-precision 9-axis inertial measurement unit 'DMU41' for railway vehicles
Supports stable vehicle operation. The latest MEMS/IMU achieving FOG-level accuracy.
In the railway industry, accurate posture control and stabilization during operation are required to improve vehicle safety and ride comfort. It is essential to accurately detect vehicle sway and provide feedback to the control system, especially in complex track conditions and environments. Inaccurate measurements can lead to control delays and decreased stability. Our product, the 'DMU41', is a high-precision MEMS/IMU that replaces fiber optic gyroscope (FOG) IMUs, enabling precise posture and position measurement of vehicles, thereby supporting stable operations. 【Usage Scenarios】 - Posture control during railway vehicle operation - Data provision for vehicle sway suppression systems - Positioning assistance in environments where GPS signals are weak 【Benefits of Implementation】 - Improved vehicle stabilization through high-precision measurements - Space-saving design due to compact and lightweight construction for vehicle installation - Reduced overall system load due to low power consumption
basic information
