Overview
Rovins is a survey-grade full-featured Inertial Navigation System (INS) for water depths up to 3,000 m. Specifically designed for offshore surveys and construction works, Rovins improves the efficiency of all subsea operations where accurate position, heading and attitude are key benefits, thanks to its advanced Kalman filter, Rovins is offered in stand-alone option or “DVL ready”.
