With this sensor, you gain reliable, precise heading for radar overlays and MARPA calculations, even in heavy seas. The 3-axis accelerometer and rate gyro deliver accurate heading, pitch, and roll data in static and dynamic conditions, while temperature compensation ensures stable performance across the operating range. Data output compatibility means seamless integration with either NMEA 0183 or NMEA 2000 networks, at 10 Hz by default and up to 20 Hz on NMEA 2000 for more responsive displays. The auto-calibration feature minimizes drift over time, and the rugged IPX6 enclosure stands up to spray and rain. Compact dimensions and straightforward mounting on angled bulkheads make installation flexible for helm spaces.
