Each system is designed to provide heading, Rate of Turn (ROT) and position information to the Simrad autopilot range and the Simrad MX Series of navigation and AIS transponder systems.
The new compasses are built on the existing technology from the MX Marine brand, which has now been incorporated into the Simrad Professional Series of products.
Each compass has dual IMO compliance certification for both navigation and heading functions, eliminating the requirement for a separate navigation antenna, and offers pitch, roll and heave (in NMEA 0183 format) as a standard output with 1 – 20Hz position and heading updates.
Three integrated sensors (gyro and two tilt sensors) are included to reduce the Real-Time Kinematic (RTK) search volume when computing GPS satellite positioning data.
The company says that a heading accuracy of less than 0.5° RMS is achievable, together with less than 1.0m DGPS positioning accuracy.
The Simrad HS80 is supplied with NMEA 2000 as the standard interface, but can be used as an NMEA 0183 device with an optional cable. Alternatively, the standard interface available on the MX575C is NMEA 0183, but can also be used as an NMEA 2000 device with an optional adaptor.
