Introducing the MSC 10 Marine Satellite Compass from Garmin — a compact, fully integrated GPS-based heading sensor with an attitude and heading reference system (AHRS) that delivers precise heading and motion data for your entire vessel's navigation ecosystem.
Why choose MSC 10 for your boat
GPS-based heading with attitude data — built-in AHRS filters and smooths GPS-derived heading for reliable orientation at all speeds and conditions.
Seamless backup navigation — seamlessly transition from GPS-based heading to magnetometer-based heading if satellite signal is lost (magnetometer calibration required for backup magnetic heading support).
High-precision positioning — multi-band GNSS receiver (L1 and L5 GPS) delivers position accuracy to within 1 meter with a 2-degree RMS heading accuracy in dynamic situations.
Heave information at your fingertips — send accurate boat heave data to your chartplotter via the NMEA 2000 network for improved 3D situational awareness.
Versatile integration — use MSC 10 as the primary sensor for autopilots and other onboard systems that require precise heading information, and enjoy effortless integration into your Garmin marine ecosystem.
Fast, reliable updates — 10 Hz position update rates provide high-sensitivity tracking and smooth heading data even in choppy conditions.
Effortless installation — 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.
