OCTANS SUBSEA

Subsea gyrocompass and motion sensor

High-performance subsea gyrocompass and motion sensor

3 000 m depth rating

0,1 deg heading accuracy

OCTANS 3000 is a subsea survey-grade gyrocompass and complete motion sensor for water depths up to 3,000 m. Based on iXBlue’s fiber-optic gyroscope (FOG) technology it outputs heading, roll, pitch, heave, rate of turn and acceleration. OCTANS 3000 can be easily upgraded to full INS mode (i.e. ROVINS).


Benefits

  • High-performance real-time outputs of true heading, roll, pitch, heave, surge, sway, acceleration and rate of turn

  • No spinning element hence maintenance free

  • Lightweight corrosion free housing for water depth up to 3 000 m, easy to integrate and interface, saves valuable mobilization time

  • Ultimate sub-metric performance using sparse array transponders and on-the-fly calibration

  • Obtain INS-class system with simple software upgrade


Features

  • Complete gyrocompass and motion sensor

  • Smart HeaveTM

  • Fiber-optic gyroscope (FOG), unique strap-down technology

  • Ethernet, web-based man-machine interface (MMI)

  • Titanium made, small, portable plug and play system

  • Optional full featured inertial navigation system
