Simrad HS65 GNSS Compass

SKU: 000-16235-001

Engineered for dependable navigation performance, the HS65 delivers high-precision GNSS heading with <2° RMS accuracy, providing stable data immune to the magnetic interference* that affects traditional compasses. Its integrated dual-layer backup system uses Dead Reckoning to maintain reliable heading for up to three minutes during temporary GNSS signal loss before automatically transitioning to magnetic backup. With seamless NMEA 2000® integration and a compact low-profile design, the HS65 delivers reliable performance for autopilot, radar overlay, and integrated navigation systems.

Product details

Designed for light commercial and non-IMO vessels, the Simrad® HS65™ GNSS Compass is ideal for OEM builders, installers, and fleet operators requiring accurate, reliable heading data for integrated bridge systems. Perfect for workboats, patrol vessels, passenger vessels, commercial fishing boats, and other professional marine applications.

Accurate GNSS heading and positioning data

The HS65 uses multi-constellation GNSS technology—including GPS, GLONASS, Galileo, BeiDou, and QZSS—to deliver precise heading and position data you can rely on. With heading accuracy under 2° RMS and sub-meter positioning, it provides the dependable data modern navigation systems demand. The result is confident vessel control and reliable navigation performance in real-world operating conditions.

Stable heading for autopilot, radar overlay, and navigation

Consistent heading data keeps radar overlays aligned, autopilot steering smooth, and charts accurately oriented. The HS65 provides stable output that allows integrated systems to work together the way they should—helping operators maintain situational awareness and stay focused on the job at hand.

Built-In Heading Redundancy

The HS65™ features a dual-layer backup system designed to maintain reliable heading data. If GNSS signal is temporarily lost, built-in Dead Reckoning seamlessly maintains reliable heading for up to three minutes before automatically switching to magnetic backup for continued heading data and added confidence when conditions change.

All-in-one sensor simplifies installation

By combining GNSS positioning and heading sensing into a single unit, the HS65 reduces system complexity and installation time. Fewer components mean simpler wiring, faster installations, and fewer potential points of failure across the network.

Modern low-profile design

A compact, low-profile design makes the HS65 easy to install across a wide range of vessel types. Flexible mounting options and improved cable routing allow installers to position the sensor for optimal satellite visibility while maintaining a clean, professional installation.

Flexible Installation Options

The HS65 supports multiple installation methods—including pole mount, direct surface mount, and through-roof mounting—to accommodate a wide range of vessel configurations. This flexibility allows installers to position the sensor for optimal satellite visibility and system performance. Rear-facing cable ports further simplify routing and help ensure clean, efficient installations. Pole mount sold separately.
