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.


Benefits

  • Accurate georeferenced position and attitude at high frequency
  • High reliability and low maintenance
  • Flexible and scalable configuration for all deployment scenarios and mission sequences
  • Immediate availability for all vehicles
  • Ultimate sub-metric performance using sparse array
  • Immediately compatible
  • Outstanding image georeferencing

Features

  • All-in-one high-accuracy 3D positioning with heading, roll and pitch, ROT and 3D speeds
  • Unique FOG strap-down technology
  • Multiple interfaces (DVL, USBL, LBL, RAMSES, GPS, depth sensor)
  • DVL Ready pre-calibrated option available
  • RAMSES synthetic baseline positioning system (option)
  • OCTANS footprint compatible
  • Post-processing software option
