Simrad HS75 GNSS Compass

HS75 Compass GNSS (000-16143-001)

Enhance your vessel’s navigation, autopilot and radar systems with the Simrad HS75 GNSS Compass (00016143001), engineered for commercial-grade heading accuracy, multi-constellation support and robust marine performance.

Ideal for serious boaters, commercial craft and fast-moving marine equipment, this compact sensor delivers precision you can rely on.

• Multi-GNSS support: GPS, GLONASS, BeiDou, Galileo and QZSS are all supported for global satellite coverage and optimum positioning. 
• Exceptional heading accuracy of 0.75° RMS, far surpassing typical magnetic rate compasses and without the complexity of a gyro compass. 
• Stationary heading capability — unlike standard GPS receivers that estimate heading only when moving, the HS75 provides accurate heading even when your boat is not underway, thanks to integrated gyro and tilt sensors that back up heading when a GNSS signal is temporarily unavailable. 
• High-update rate and fast position fixes: The receiver computes your position at up to 20 times per second, enabling rapid response for fast powerboats and high-speed marine equipment. SBAS (Satellite Based Augmentation Systems) support gives enhanced positional precision where available. 
• Advanced motion sensing: Beyond heading and position, the HS75 measures your vessel’s rate of turn, heave, pitch and roll, feeding this data via your NMEA 2000® network to optimize autopilot performance and sonar systems that compensate for wave motion. 
• Plug-and-play simplicity: A small form-factor unit (~ 348 mm length, 158 × 74 × 348 mm overall) weighing 0.75 kg mounts easily to a flat surface or a pole, with surface- and pole-mount options available. 
• Rugged, marine-ready design: Operates from 6-36 V DC, draws ~3.2 W typical power, rated for humidity (95% non-condensing), operating temperature from –40 °C to +70 °C and storage up to +85 °C. Waterproof to IPX7. 
• Full NMEA 2000® support: Compatible PGNs including vessel heading, rate of turn, GNSS position data, position delta, COG & SOG rapid update, altitudes and more. Integrates with autopilot systems, radars, chartplotters and displays. 

Why Choose the HS75 GNSS Compass?
When your marine electronics demand pinpoint accuracy and reliability — whether for autopiloting, radar stabilization or integrating high-speed vessel movement — the HS75 delivers a premium solution.

Its upgraded support for multiple GNSS constellations ensures stronger global coverage; the on-board sensors compensate for signal gaps or vessel movement; and its compact, rugged design simplifies installation.

For boaters navigating commercial or performance applications, the HS75 brings gyro-level heading accuracy without the cost or maintenance overhead of traditional gyrocompasses.

Use Cases & Benefits

• Autopilot heading source: With 0.75° accuracy and high-update data, the HS75 helps maintain smoother, more precise course control.
• Radar/sonar stabilization: Heave, pitch and roll outputs enhance sonar clarity and radar performance in rough seas.
• High-speed powerboats & commercial vessels: Rapid position updates (up to 20 Hz) and multi-GNSS coverage give the speed and precision needed at sea.
• Retrofit or new installations: Compact size and simple mount make the HS75 ideal for vessel upgrades or first-time installs.
• Global operations: With full GNSS constellation support and SBAS augmentation, you get consistent performance whether coastal, offshore or international.

Installation & Integration Tips

• Mount the unit as level as possible on a rigid surface or pole with minimal vibration.
• Use a high-quality NMEA 2000® drop-cable and ensure proper network termination for seamless integration.
• Allow clear sky view for GNSS antenna phase-centres to get optimal heading accuracy — even though the HS75 does have gyro/tilt backup.
• For technical systems (autopilot, radar), map the PGNs listed in the spec sheet so heading, rate of turn, heave/pitch/roll feed into your system properly.
• Double-check supply voltage (6-36 V DC) and proper power wiring to minimise noise and ensure signal integrity.

With the Simrad HS75 GNSS Compass, you’re investing in a top-tier marine heading sensor engineered to deliver ultra-precise heading, fast positioning and full motion sensing in a compact and easy-to-install package.

Whether you’re upgrading your vessel’s autopilot heading reference, enhancing radar performance, or building a high-performance marine electronics suite, the HS75 stands out for reliability, accuracy and simplicity.
