Overview

The Garmin 010-11417-00 is a 3-axis heading sensor that outputs heading data over NMEA 0183 or NMEA 2000 for accurate radar overlay and MARPA functions on compatible systems. It uses a solid-state compass with an integrated accelerometer and rate gyro, delivering better than 1 degree static heading accuracy and 2 degrees dynamic accuracy with up to 30 degrees of pitch and roll.

It runs on 9 to 16 VDC and comes in an IPX6-rated housing for wet helm areas and washdowns. Physical size is about 2 in high by 4.4 in long by 4.5 in deep, which helps when space is tight inside a console or under a dash.

Key features

• Better than 1 degree static heading accuracy; 2 degrees dynamic accuracy with up to 30 degrees of pitch and roll
• Heading output is 10 Hz by default on both NMEA 0183 and NMEA 2000; NMEA 2000 output can be up to 20 Hz
• NMEA 0183 and NMEA 2000 data output support to fit different network and wiring setups
• Three-axis solid-state compass plus accelerometer and rate gyro for stable heading data when the boat is moving
• IPX6-rated waterproof housing for spray and deck wash conditions
• Mounts on an angled bulkhead and supports auto-calibration for a shorter setup process

Installation and setup

Mount the sensor on a solid surface where it will not be kicked or used as a handhold. Like any compass-based sensor, it needs some distance from magnetic sources such as speakers, large DC motors, or high-current wiring runs.

The enclosure can be mounted on an angled bulkhead, which helps when the best location is under a console or inside a helm station. After mounting and wiring, complete the calibration steps on the connected display so the heading aligns correctly with the boat.

Electrical and data output

Power range is 9 to 16 VDC. Data output can be set up on either NMEA 0183 wiring or a NMEA 2000 backbone, depending on how the rest of the electronics are networked.

NMEA 0183 and NMEA 2000 cables are sold separately, so plan the correct cable type for your existing system before installation.

Compatibility and fit

This sensor is used when a vessel needs consistent heading input for features like radar overlay and MARPA tracking. Confirm that your display, radar, or other onboard electronics accept heading input via NMEA 0183 or NMEA 2000 and that the installation location can stay clear of magnetic interference.

Use cases on board

A good match for helms that rely on radar overlay, MARPA target tracking, or any setup where heading needs to stay steady during turns, chop, and acceleration. It also fits well on boats that see frequent pitch and roll, since the rate gyro helps maintain heading accuracy under dynamic motion.

Maintenance and care

Periodically check that the mounting hardware stays tight and that the cable routing is supported so vibration does not work the connections loose over time. If electronics are moved near the sensor later, re-check heading alignment since magnetic changes onboard can affect compass-based devices.
