Xsens Sirius AHRS

Xsens Sirius AHRS fuses calibrated gyroscope, accelerometer and magnetometer measurements into roll, pitch and true-north-referenced heading. Published performance includes 0.2-degree RMS roll and pitch, one-degree RMS heading and real-time heave output. The inertial signal chain is designed to reject vibration and shock, with analogue filtering supporting stable orientation data on vehicles and machinery.

The anodized aluminium enclosure measures 56.5 × 40.9 × 24.75 millimetres, weighs 78.5 grams and carries IP68 protection. RS232, RS422 and CAN interfaces expose Xbus, NMEA and CAN protocols, with output rates up to two kilohertz and 400-hertz strapdown integration. Xsens supplies MT Manager, an SDK, ROS support and magnetic-field calibration tools for configuration, logging and host-system integration.
