SI-TEX NMEA2000 GNSS SAT Compass w/Pole Mount (No Cable Included)

Need to add a rock-solid heading source to your NMEA 2000 network? The SI-TEX SATCOMPASS is a powerful, yet straightforward GNSS satellite compass designed for just that. It is a self-contained heading sensor that uses a multi-band GNSS receiver and a 9-axis inertial sensor to deliver incredibly accurate and stable heading data directly to your boat’s NMEA 2000 backbone. Because it is satellite-based, it is completely immune to the magnetic interference that can throw off traditional compasses, making it perfect for any type of vessel.

This unit is built tough, with an IPX7 submersible waterproof rating, meaning it can take a serious soaking and keep working. It is designed to be pole-mounted on a standard 1-inch 14-thread mount, placing it up high with a clear view of the sky. The internal 9-axis inertial sensor helps to smooth the data and provide stable output even if the boat is pitching and rolling. It is a simple, powerful, and cost-effective way to get professional-grade satellite heading onto your network.

Helm Use and Readability

Like other heading sensors, the SI-TEX SATCOMPASS works behind the scenes. You will not look at it directly. Instead, you will see its benefits on your other NMEA 2000 displays. Your chartplotter’s radar overlay will be perfectly aligned, your autopilot will steer more accurately with less hunting, and your fishfinder’s chart-plotting feature will be more precise. It is a background upgrade that makes all of your other helm electronics work better.

Why Choose the SI-TEX NMEA2000 GNSS SAT Compass

The SATCOMPASS from SI-TEX is a fantastic choice for its simplicity and power. It is one of the easiest ways to add the significant benefits of satellite heading to any boat with an NMEA 2000 network. Its immunity to magnetic interference, combined with its advanced inertial stabilization and rugged IPX7 build, makes it a huge upgrade over any fluxgate compass. If you want better autopilot performance and a more reliable heading source, this is a smart, cost-effective solution.

Before Ordering the SI-TEX NMEA2000 GNSS SAT Compass

Before ordering, confirm that your boat has an existing NMEA 2000 network with an available T-connector. Identify a mounting location that offers a clear sky view and purchase a compatible 1-inch 14-thread pole mount if you do not already have one. Note that this model does not include an NMEA 2000 drop cable, so you will need to purchase one separately that is the correct length for your installation.
