MAHRS (Meridian Attitude and Heading Reference System) is a master heading reference instrument employing the characteristics of a dynamically tuned gyro (DTG), the effect of gravity and the earth’s rotation to produce exceptional heading performance. This is combined with a Dynamic Motion Sensor (DMS) to provide accurate attitude measurement readings.

MAHRS has been designed to provide reliable maintenance free operation. The remarkably stable heading performance can be maintained for turn rates in excess of 200deg/s making the system ideal for use on fast survey craft and in river/harbor environments.

The unit provides 0.2deg secant latitude RMS dynamic heading accuracy as well as 0.03??deg RMS (for a 5??deg amplitude) or 0.05deg RMS (for a 45deg amplitude) dynamic roll and pitch accuracy to offer the full AHRS performance.
