ROVINS

Subsea INS

Survey Grade Inertial Navigation System

3 000 m depth rating

0,05 deg heading accuracy

ROVINS is a survey-grade full featured inertial navigation system for water depths up to 3 000 m. Designed specifically for offshore survey and construction works, ROVINS, thanks to its advanced Kalman filter, improves the efficiency of all operations where accurate position, heading and attitude are key benefits. ROVINS is offered in stand alone, «DVL ready», and ROVINS 154 (for OEM integration) versions.
