      AHRS-8

      $1,850

      Fully temperature compensated, the AHRS-8 is individually calibrated for industry-leading heading accuracy. Our AdaptNav II™ algorithm provides accurate in-field calibration, while the NorthTek™ Development System makes it the world’s only fully programmable inertial system.

      • Integrated AdaptNav II™ provides real-time noise characterization and active gyro drift compensation for superior heading, pitch and roll performance in electrically and mechanically noisy environments

      • Fully temperature compensated over the entire operating range, individually calibrated from -40⁰ to +70⁰ C

      • Powerful user programmable sensor customization apps via NorthTek™ Forth interpreter

      • 2D and 3D adaptive in-field cal providing hard and soft magnetic interference compensation

      • Advanced sensing technology (3-axis magnetic, 3-axis MEMS acceleration, and 3-axis MEMS gyro)

      • Selectable 4g or 8g accelerometer ranges, suitable for highly dynamic application environments

      • Magnetic and True North heading (yaw), pitch, and roll measurement

      • Full 360° rollover capability

      • Low power consumption and power management (Sleep Mode) functionality

      • Supports multiple communication protocols

      • In-field calibration point selection and distribution indicator

      • Quality of in-field calibration indicator

      • Centripetal acceleration correction
