AHRS-8
Couldn't load pickup availability
For AHRS replacement in existing programs only. Not recommended for future designs due to obsolescence issues.
Fully temperature compensated, the AHRS-8 is individually calibrated for industry-leading heading accuracy. Our AdaptNav™ algorithm provides accurate in-field calibration, while the NorthTek™ Development System makes it the world’s only fully programmable inertial system.
-
Integrated AdaptNav™ 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
