Overview
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.
Features
Titanium case enable it to work under 6000m deep sea.
Three-axis FOG: Small size, low consumption, low weight
Fast alignment, 10 minutes
Integrated to GNSS/EM LOG/DVL/USBL
Free maintenance
Application
ROV subsea positioning and navigation
Trencher or tractor
Attitude and motion sensor for seabed
