IMU inertial system RMCU

AHRSMEMSmotion control

The Railway Motion Control Unit - RMCU is a high-performance strapdown system that was developed for Railway application in order to determine absolute orientation (Heading, Pitch and Roll) and parameters of motion (Angular Rates and Linear Accelerations) for any Railway Platforms on which it is mounted. Orientation is determined with high accuracy for both motionless and dynamic applications. The Inertial Labs RMCU utilizes 3-axes each of precision MEMS accelerometers, miniature Fluxgate magnetometers and MEMS gyroscopes to provide accurate Heading, Pitch and Roll of the device under measure. Integration of gyroscopes’ output provides high frequency, real-time measurement of the device rotation about all three rotational axes. Accelerometers and Fluxgate magnetometer measure absolute, very accurate in static and dynamic conditions Pitch, Roll and Heading/Azimuth at RMCU initial alignment as well as providing ongoing corrections to gyroscopes during operation. Heading static accuracy, RMS 0.3 deg Heading dynamic accuracy in temperature range, RMS 0.6 deg Pitch & Roll static accuracy, RMS 0.05 deg Pitch & Roll dynamic accuracy in temperature range, RMS 0.08 deg Dimensions 129 × 53 × 49 mm Weight 120 grams Interface RS-485 / Ethernet KEY FEATURES AND FUNCTIONALITY • EN 45545, EN 50155 and EN 50011 Railway standards compliant solution • One model with multiple configurations at an exceptional price performance ratio • State-of-the-art algorithms for different Railway Platforms • Highly accuracy miniature Fluxgate magnetometer • Gyro-Stabilized Slaved Magnetic Heading • Suitable for Trains Motion Control and Primary Attitude Reference
