Sales Enquiry

    The Simrad HS80A GNSS compass is type-approved to the latest IMO regulations including RAIM (Receiver Autonomous Integrity Monitoring). The HS80A delivers heading accuracy of better than 0.5° and provide sub-meter DGPS positioning accuracy. This level of accuracy is achieved in the HS80A from SBAS.


    Both the HS80A has two IMO compliance certifications which is a big advantage for Simrad customers. A separate IMO compliant antenna is not required as the compasses meet both navigation and heading function approvals.


    Integrated Gyro and tilt sensors deliver fast start-up times and provide heading updates during temporary loss of satellites.


    The HS80A is supplied with NMEA 2000 as the standard interface, but can be used as a NMEA 0183 device with an optional cable.
