    IMO approved

    Our GPS compass solutions are designed to provide reliable heading, ROT (Rate of Turn), and position information to Simrad Autopilots and the MX5XX Series of navigation and AIS transponder systems.

    The Simrad HS80 GPS compass is type-approved to the latest IMO regulations including RAIM (Receiver Autonomous Integrity Monitoring). The HS80 delivers heading accuracy of better than 0.5° and provide sub-meter DGPS positioning accuracy. Its accuracy comes from SBAS.

    The heading (HDT) output rate is normally configured to 10 Hz output. Position output from 2, 5 and 10 Hz is available with the optional multi-hertz license in the Simrad-MX CDU.


    The HS80 has two DNV 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.


    There are three supplementary sensors (gyro and two tilt sensors) that are integrated into the units main PCB. These sensors act to reduce the Real-Time Kinematic (RTK) search volume when computing GPS satellite positioning data. This helps improve heading start up and reacquisition times.


    The HS80 is supplied with NMEA 2000 as the standard interface, but can be used as a NMEA 0183 device with an optional cable.
