1.4 Understanding the MX575 D/GPS Satellite Compass
The MX575 is a complete GPS heading and positioning system in a single
enclosure that requires only one power/data cable connection. It has been
designed primarily for the Marine market applications. This manual has been
written to address the primary uses of the MX575 in the Marine industry.
The MX575 houses two tightly coupled high-performance GPS receivers, dual
GPS antennas, a DGPS beacon receiver module, power supply circuit, a single-
axis rate gyro, a tilt sensor, and H-field internal beacon antenna. The rate gyro
and tilt sensors are used to improve system performance and to provide backup
heading information in the event that the primary GPS heading solution is not
available due to GPS signal blockages.
