How to Calibrate USBL Systems | DP Vessel, Non-DP & Barge Setup Guide

✅Want accurate underwater positioning? It starts with proper USBL calibration. In this video, we break down everything you need to know about calibrating Ultra Short Baseline (USBL) systems across different vessel types—DP vessels, non-DP vessels, and barges. You should watch this video first    • Basic Concept of USBL & Underwater Positio...   📐 What you’ll learn: ✅Pre-calibration essentials: GPS offsets, gyro compass alignment, motion sensor setup ✅Why sound velocity profiles matter—and how to measure them correctly ✅USBL calibration methods: 👉Dynamic Calibration for DP vessels using cardinal points 👉Line Run Calibration for non-DP vessels with diver/ROV support 👉Static Calibration for barges using offset beacons ✅How to position beacons, log data, and avoid common errors ✅What orientation error and range ratio mean—and how to calculate them ✅Why roll/pitch calibration isn’t possible in static setups ✅How sound velocity and ray bending affect beacon accuracy ✅What exactly is being calibrated: installation errors, alignment, and signal path distortion ✨This tutorial is ideal for offshore surveyors, marine engineers, and anyone working with acoustic positioning systems. Whether you're deploying towfish, installing subsea structures, or tracking divers, USBL calibration is critical to mission success. 👍 Like, 💬 Comment, and 🔔 Subscribe for more offshore surveying tutorials, geodesy insights, and real-world engineering workflows. #USBLCalibration #OffshoreSurveying #MarineGeodesy #DPVessel #BargeSurvey #AcousticPositioning #UnderwaterTracking #SoundVelocityProfile #ROVTracking #AlwaysBeCurious : Chapters in this video : 00:00 Intro 00:17 To Do Before Cal 01:20 Sound Velocity Profile 01:42 Where We Use USBL 02:40 Types of Calibration 03:45 Dynamic Calibration 05:12 Line Run Calibration 06:44 Recap till now 07:59 Static Calibration 11:45 What we actually Calibrate? 13:22 SVP & Ray Bending 15:34 Thanks for watching
