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
