The Garmin MSC™ 10 Marine Satellite Compass Heading Sensor and Multi-band GPS Receiver – White (Part Number 010-02407-00) is a high-precision marine position and orientation system featuring dual-frequency multi-band GNSS technology to deliver true heading accuracy within 2 degrees RMS. Engineered for demanding navigation setups, it utilizes multi-constellation support across GPS (L1/L5), GLONASS, Galileo, and BeiDou networks alongside a rapid 10 Hz position update rate, providing sub-meter position accuracy and ultra-smooth chartplotter rendering. By tracking satellite signals rather than relying on magnetic sensors, the satellite compass remains completely immune to onboard magnetic interference, engine iron, and local anomalies, ensuring reliable autopilot tracking, stable radar overlays, and precise MARPA target acquisition even under harsh sea conditions.
Housed in a UV-resistant, IPX7 waterproof white dome, the unit features an integrated Attitude and Heading Reference System (AHRS) that delivers dynamic heave (accurate to 8 cm RMS), pitch, and roll data to stabilize sonar readings and vessel tracking. Operating on a 9 to 32 VDC power supply with an NMEA 2000 Load Equivalence Number (LEN) of 6, the sensor interfaces directly via the NMEA 2000 network for clean plug-and-play integration across compatible Garmin marine ecosystems. In the rare event of a satellite signal loss, the system seamlessly transitions to an internal backup magnetometer, offering a complete, maintenance-free primary heading and positioning solution in a classic white marine finish.
