Simrad MX575D DGPS Compass With GLONASS


The Simrad MX575D D/GNSS compass is type-approved to the latest IMO regulations including RAIM (Receiver Autonomous Integrity Monitoring). The MX575D delivers heading accuracy of better than 0.5° and provide sub-meter DGPS positioning accuracy. This level of accuracy is achieved in the MX575D by using the RTCM correction data supplied from its internal beacon demodulator or from SBAS.

Type Approvals

Both the MX575D 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.

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

The standard interface on the MX575D is NMEA 0183, but can also be used as a NMEA 2000 device with an optional adaptor.
