Garmin MSC 10 Marine Satellite Compass, Heading Sensor and Multi-Band GPS Receiver
The Garmin MSC 10 is an NMEA 2000 certified marine satellite compass weighing 1.12 lbs and measuring 6 × 13 × 3 inches, built around a multi-band GNSS (L1 and L5) and multi-constellation receiver. Marine electronics technicians and vessel owners install the unit as a primary heading and position sensor for chartplotters, autopilots, and other onboard navigation systems.

Compatibility & Applications
- Wires directly into any existing NMEA 2000 network as a plug-and-play sensor node.
- Pairs with Garmin GPSMAP 8400/8600 series chartplotters as a primary heading source.
- Pairs with Garmin GPSMAP 7×3, 9×3, 12×3, 10×2, and 12×2 series chartplotters.
- Mounts as the primary heading sensor for Garmin Reactor autopilot series installations.
- Delivers heading, pitch, roll, and heave data to compatible Garmin chartplotters via NMEA 2000.
- Connects to third-party NMEA 2000 displays using basic calibration mode.
The MSC 10 is NMEA 2000 certified and requires no calibration for GPS-based heading—no magnetic deviation corrections, no swinging the vessel. The built-in attitude and heading reference system (AHRS) filters GPS-derived heading at all speeds, including sharp turns and stationary conditions, distinguishing the unit from conventional fluxgate compass sensors.
