Meet the MSC 10 Marine Satellite Compass from Garmin — a compact, GPS-based heading sensor with an integrated AHRS that delivers precise heading and motion data for your vessel’s navigation ecosystem. It integrates seamlessly within Garmin’s marine ecosystem and can serve as the primary heading sensor for autopilots and other onboard systems.
-
Integrated AHRS: Attitude and heading reference system that filters and smooths GPS-derived heading for reliable orientation at all speeds and conditions.
-
Multi-band GNSS (L1/L5): Multi-band GNSS receiver (L1 and L5 GPS) enhances position reliability in challenging environments.
-
Positioning accuracy: Positioning accuracy within ~1 meter.
-
Heading accuracy: Dynamic heading accuracy of approximately 2° RMS in motion.
-
10 Hz update rate: 10 Hz position update rate for high-sensitivity tracking and smooth heading data in chop.
-
NMEA 2000 heave data: Sends accurate boat heave data to your chartplotter via the NMEA 2000 network for improved 3D situational awareness.
-
Primary sensor for autopilots: Can serve as the primary heading sensor for autopilots and other onboard systems that require precise heading information.
-
GPS-to-magnetometer fallback: Seamless backup from GPS-based heading to magnetometer-based heading if satellite signal is lost (magnetometer calibration required for magnetic heading backup).
-
Easy installation and Garmin ecosystem compatibility: Compact design with simple installation and no calibration required unless you plan to use magnetometer-based heading; fully designed to work harmoniously with Garmin devices and networks.

The MSC 10 delivers reliable heading and motion data to your helm, chartplotter, and autopilots, enabling accurate navigation decisions across speeds and sea conditions. Its high-precision positioning, 10 Hz updates, and seamless fallback to magnetic heading help maintain orientation when satellite signals waver. With easy installation and full Garmin ecosystem compatibility, setup and operation are straightforward, while built-in heave data enhances 3D situational awareness for safer, more informed navigation.
