Ray Trace Tool 2.9

Ray Trace Tool by Sonardyne International Ltd. is a desktop application for modeling how acoustic signals travel through the water column. It calculates ray paths and travel times using measured or modeled sound speed profiles, helping you quantify refraction effects and reduce positioning error. Designed to support the setup, validation, and optimization of Sonardyne acoustic positioning and communications systems, it enables better planning, faster commissioning, and more reliable offshore operations.

Key capabilities:

• Import sound velocity profiles (SVP) from common sources and formats, including CSV
• Visualize sound speed versus depth and the bending of acoustic rays between a transceiver and subsea target
• Configure scenarios with vessel and target depths, separation, and geometry to assess expected performance
• Predict refraction effects, travel times, shadow zones, and potential multipath
• Generate and export ray-trace correction data for use with compatible Sonardyne topside software and instruments
• Support planning, real-time validation, and post-mission analysis in a simple, field-ready interface

Who it’s for:

• Hydrographic surveyors and subsea positioning specialists
• Offshore construction and operations teams
• ROV/AUV pilots and acoustic engineers seeking to improve USBL/LBL accuracy and reliability

With clear visualizations and practical outputs, Ray Trace Tool helps you turn sound speed measurements into actionable corrections that enhance the accuracy and consistency of Sonardyne-based acoustic positioning.
