MX575A DGPS Compass
The MX575A D/GPS compass is designed to provide the
Simrad Professional Autopilots, MX5XX Series 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 10 Hz when using RTCM correction data
supplied from internal beacon demodulator.
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. The MX575A features
two independent RS-232 serial ports and one RS-422 port. The output of the RS-422 port mirrors that of one RS-232 port. It also
features COAST™ 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.
