Detailed description
Detailed description
Designed for demanding marine navigation, the Garmin Marine Satellite Compass MSC™ 10 is a GPS-based heading sensor and multi-band GPS receiver. It provides heading, position, heave, pitch, and roll data with high accuracy for onboard systems. Unlike traditional magnetic compasses, the MSC 10 is unaffected by magnetic interference, ensuring consistent heading reliability. It differs from simple GPS receivers by providing true heading even when stationary or at low speed, thanks to its integrated AHRS.
Accuracy and technical performance
The MSC 10 integrates a multi-band (L1 and L5) and multi-constellation GNSS receiver, supporting GPS, Galileo, GLONASS, and BeiDou systems. This advanced architecture guarantees a heading accuracy of 2 degrees RMS and a position accuracy of less than 1 meter CEP (less than 3 meters for 95% of the time in typical marine use). The 10 Hz position update rate enables dynamic tracking. Its 8 cm RMS heave accuracy is a key asset for data stability. The integrated AHRS ensures stable GPS heading at all speeds, including in heavy seas or tight turns. This device is an ideal primary sensor for autopilots, such as the Garmin Reactor series, where it enhances heading accuracy and consistency for more efficient navigation and fuel savings. It also contributes to more precise radar traces when paired with a compatible radar.
Integration and installation flexibility
With NMEA 2000 compatibility, the Garmin MSC 10 easily integrates into an existing onboard network, directly transmitting heading, pitch, roll, and heave data to compatible Garmin chartplotters. The unit can be mounted on a flat surface or on a standard 1-inch diameter mast with a 14 threads-per-inch (TPI) thread (mast not included). A clear view of the sky and horizon is required for optimal performance. For situations where GPS signal may be weak or blocked (under bridges, near tall structures), the MSC 10 features an internal magnetometer usable as a backup sensor, requiring prior calibration. Installation is facilitated by the inclusion of a 6 m NMEA 2000 drop cable, a T-connector, a gasket, and mounting hardware (M4 x 0.07 x 45 bolts, washers, hex nuts). Adhesive is also included for mast mounting.
