HS65 GNSS Heading SensorThe HS65 is an all-in-one GNSS-based heading sensor that combines compass and positioning functionality in a single device, simplifying installation while delivering stable, precise heading information critical to navigation, autopilot control, radar overlay, and overall system performance.The HS65 replaces the Simrad HS60 and represents an evolution in both performance and installation flexibility, informed by real-world customer and installer feedback.The Simrad HS65 is a GNSS-based heading sensor that provides accurate, interference-free heading and positioning data for Simrad marine electronics systems. Using satellite-based heading rather than magnetic sensors eliminates interference from onboard electronics and metals.Features:All-in-one heading and position sensor combining a compass and a satellite in a single deviceHigh-precision performance with less than 2 heading accuracy and under 1 meter position accuracyDead reckoning capability to maintain heading temporarily if the satellite signal is lostSeamless integration with Simrad systems via NMEA 2000 connectivityModern low-profile design with improved cable routing and flexible installation optionsWhy It Was Created?Modern marine systems rely on precise heading data to support accurate navigation, radar overlay, chart alignment, and autopilot performance. The HS65 was developed to deliver a more reliable and simplified heading solution that improves system accuracy and installation flexibility. It provides consistent, satellite-based heading data, simplifies integration with Simrad chartplotters and autopilot systems.The HS65 provides critical heading and positioning data that supports multiple onboard systems, including:Autopilot systems for accurate course keepingRadar overlay and MARPA target trackingChart orientation and navigation accuracyOverall situational awareness and vessel controlDesigned to integrate seamlessly with Simrad marine electronics systems running on both NOS and NEON OS, including NSO, NSS, and NSX platforms.
