ELECTROMAGNETIC COMPASS OVERVIEW

The MD53A/B from Marine Data is an Earth’s Field Electromagnetic Compass which directly senses the Earth’s magnetic field. The MD53A/B has no moving parts and does not require a host magnetic compass. In this way, the MD53A/B forms the sensing element of a solid-state Electromagnetic Compass (EMC) system – an alternative or a backup to a Gyro system.

The MD53A/B provides digital NMEA 0183 heading data (HDT, HDG, HDM) when used with the Marine Data MD97CSP Compass Sensor Interface. Vessel heading may be transmitted to any location on the vessel and displayed with a Marine Data compass heading repeater. Magnetic corrections and heading fluctuation damping are applied with the Marine Data MD71THD Variation and Deviation Corrector or the MD86HCU Heading Comparator Unit.

Constructed from robust aluminium alloy and finished in RAL7040 Window Grey semi-gloss paint, the MD53A/B is designed to complement existing marine navigation equipment.

The MD53A/B Electromagnetic Compass from Marine Data: Flexible in application, easy to install and simple to maintain.
