Meridian MAHRS

MAHRS is a master heading reference instrument employing characteristics of a dynamically tuned gyro (DTG). The device is capable of monitoring the earths gravity and rotation, providing exceptional heading performance and the ability to produce a true north reference. This is also combined with a dynamic motion sensor (DMS) which is able to provide an accurate heave, roll and pitch. By closely coupling the two sensors, the MAHRS becomes a simple and fast method of providing accurate heading and attitude data.

MAHRS has been designed to provide reliable, maintenance free operation with a computed MTBF of 30,000 hours. The remarkably stable heading provided by MAHRS can be maintained for turn rates in excess of 200° per second making the system ideal for use on fast survey craft and in river/harbour environments.
