Detailed description
Detailed description
The Simrad HS75 GNSS compass is a high-precision heading and positioning sensor designed for vessels requiring reliable navigation data that is completely immune to magnetic interference. Unlike a traditional fluxgate compass, the HS75 uses a dual GNSS antenna to calculate heading with an accuracy of 0.75° RMS, while providing pitch, roll, and heave data at a 10 Hz update rate.
Multi-constellation precision and inertial sensors
This receiver features 422 channels and decodes GPS, GLONASS, BeiDou, Galileo, and QZSS signals, paired with SBAS corrections (WAAS, EGNOS, MSAS). This redundancy ensures rapid acquisition and a heave accuracy of 30 cm. In the event of temporary satellite signal loss, the HS75 integrates a six-axis gyroscope that maintains reliable heading for up to 3 minutes, supported by an inclinometer for pitch and roll data (accuracy of 1.5° RMS).
Network integration and rugged design
Built for the harshest marine environments, its compact housing (34.8 x 15.8 x 6.5 cm, 0.75 kg) carries triple IPX6, IPX7, and IPX9 waterproof certifications. It connects directly to an NMEA 2000 network via a standard Micro-C connector. With a wide 6 to 36 V DC power range and very low power consumption of 3.2 W, it integrates seamlessly into the Navico ecosystem (Simrad, B&G, Lowrance). It positions itself as a direct competitor to the Garmin MSC 10, offering professional-grade performance for high-speed powerboats and commercial vessels.
