Garmin MSC 10 Marine Satellite Compass — White (010-02407-00)
The Garmin MSC 10 is a GPS-based satellite compass that delivers precise heading, pitch, roll, and heave data to your compatible chartplotter or autopilot via NMEA 2000. Using dual-frequency multi-band GNSS and an integrated attitude and heading reference system (AHRS), it provides heading accuracy within 2 degrees at a 10 Hz update rate — without the interference issues that affect magnetic sensors near engines, wiring, or speakers.
This listing is for the White version (010-02407-00). Also available: Black (010-02407-10) — contact us if you need the black variant.

Installation Notes
Mount the MSC 10 where it has a clear, unobstructed view of the sky and can be aligned with the vessel centerline. Connect to your existing NMEA 2000 backbone using the included drop cable and T-connector. Garmin recommends updating your compatible chartplotter to the latest software version before installation. If using the backup magnetometer, calibrate it after installation per the owner's manual.

Technical FAQ
Q: How is the MSC 10 different from a standard GPS antenna with heading?
A: The MSC 10 uses multiple GNSS receivers and an integrated AHRS to calculate heading, pitch, roll, and heave — not just position. A standard GPS antenna provides location data only. The MSC 10 is purpose-built for vessels that need accurate heading at all speeds, including very low speeds where GPS-derived heading from a single antenna is unreliable.
Q: Does the MSC 10 replace a magnetic compass?
A: It can serve as the primary heading source for electronic systems (chartplotters, autopilots), but it does not replace a required magnetic steering compass for regulatory purposes. Check your vessel's requirements.
Q: What happens if I lose satellite signal?
A: The MSC 10 automatically transitions to its built-in magnetometer to maintain heading output without interruption. The magnetometer must be calibrated after installation for this fallback to function correctly.
Q: Does it work with non-Garmin chartplotters?
A: The MSC 10 outputs standard NMEA 2000 data and is compatible with any NMEA 2000-capable device. Full integration of all data fields (pitch, roll, heave) is best supported on Garmin chartplotters.
Q: What software version is current?
A: As of June 2026, software version 3.10 is current and adds auto-calibration support. Update via your compatible Garmin chartplotter.
Parts Desk Insights
Best Use Case: The MSC 10 is the right choice for vessels where magnetic compass interference is a known issue — particularly powerboats with large engines, steel or aluminum hulls, or heavy electrical systems near the helm. It's also the preferred heading source for Garmin autopilot installations where accurate low-speed heading is critical for reliable course-keeping. The pitch, roll, and heave outputs add value for offshore cruisers and sailors monitoring vessel motion in open water.
Common Issue: Customers occasionally confuse the MSC 10 with a standard GPS antenna. The MSC 10 is a dedicated heading sensor — it does not add chart data or improve chartplotter GPS positioning on its own. If you only need a GPS position source, the GPS 24xd is a more cost-effective option. Also confirm your NMEA 2000 backbone has sufficient power and drop cable capacity before ordering.
