The MX575A D/GPS compass is designed to provide the MX420 navigation and AIS systems with reliable heading, ROT (Rate of Turn) and position information. The MX575A delivers a heading accuracy of better than 0.5° at update rates of up to 10 Hz. It also provides sub-meter DGPS positioning accuracy at rates of up to 5 Hz when using RTCM correction data supplied from internal beacon demodulator.
Additional Sensors
To augment the GPS-derived heading, the MX575A includes other supplemental devices. The combination of inclinometer and magnetic sensing devices aid the rate at which a heading solution is computed on startup and also speeds up reacquisition. A rate gyro provides a secondary source of heading data in times when the GPS heading is not available due to temporary obstructions. These sensors improve performance and increase dependability of the MX575A.
Interface
The MX575A features two independent RS-232 serial ports and one RS-422 port. Either RS-232 port may be configured freely for a variety of NMEA 0183 output sentences or for the input of RTCM correction data from an external source. The output of the RS-422 port mirrors that of one RS-232 port.
COASTTM Technology
The MX575A features COASTTM technology that allows it to use old correction data for up to 40 minutes without seriously affecting positioning performance. This feature offers peace of mind and allows you to focus on more important issues than reliability of a differential signal.
