Designed to provide highly accurate heading, heave, roll and pitch MARINUS, attitude and heading reference system, is an easy to use, install and configure stand-alone unit. Users of multibeam systems require reliable attitude data, and a well supported product. TSS have designed the MARINUS product to meet this demanding requirement for high accuracy, fast output rate, and limitless motion within a small, light, rugged, and competitively priced package.
Based around a proven Ring Laser Gyroscope (RLG) the MARINUS offers outstanding accuracy in all dynamics. Allowing the very best results from multibeam systems. The industry renowned TSS real time and delayed heave algorithms are utilised by the unit, giving accurate heave measurements in all conditions, including long-period open-ocean swell.
A WindowsTM based Display and Control Software (DCS) is supplied with the MARINUS allowing interface and set up of the unit for project integration. MARINUS has a highly flexible mounting arrangement (vertical / horizontal), 3000m depth rated as standard for pole mounted sonar heads and ROV operations. Optional 6000m unit available for deeper projects.
Due to the high accuracy of the RLG elements used the unit is capable of measuring earth rotation directly leading to accurate heading without the requirement of a further ridged dual GPS antenna installation on the vessel. As MARINUS incorporates highly accurate solid-state sensing elements the unit is maintenance free (no moving parts).
