Small Size High Pressure TFG Series Subsea Inertial Navigation System Rov

1 Introduction

TFG Series Subsea Inertial Navigation System, is specially designed for ROV/Trencher, due to its high accuracy, small size and high pressure tolerance. Composed of one high accuracy three-axis FOG and three quartz accelerometer, TFG adopts high precision calibration and compensation technique to ensure its high accuracy performance under extreme conditions.

2 Characteristics

Titanium case enable it to work under 6000m deep sea.

Three-axis FOG: Small size, low consumption, low weight

Fast alignment, 1 O minutes

Integrated to GNSS/EM LOG/DVL/USBL

Free maintenance

3 Application

ROV subsea positioning and navigation

Trencher or tractor

Attitude and motion sensor for seabed
